Battery Recommendations?

[Vette Killer]

Hi All,

The battery is finally pooched...combination of not enough miles late in the year and sitting over winter...must be a couple of dead plates...

Any recommendations? I am ok with going with the stock replacement one, just curious if anyone has had any good luck with others before I go ahead and grab one tomorrow.

Thanks,

Rob

I don't recall all of the details, but I thought at one time I read a thread on a "gel" based battery for cars that tend to sit for a period of time and aren't used regularly.

Have you installed one in yours? No issues with hold down or post alignment? The closest Costco is Edmonton so a bit of a PITA to return if there are any install issues....

No, I still have the stocker in my 08, but my garage is heated and I have a tender on it when the car is away for the season, so it has been well maintained and hasn't endured a BERTA winter. :cold2:

I will be lucky if I get a 4th year out of it and if I don't I will go with the Optima.

The only guy I know who has an Optima one on here at SU, is FARMDOG.

[The Bone]

I still have the stock one and car is 5 years old still no problems. It sits all the time. I just wonder how much I have left in it. I had to add some distilled water to it the other day. I did find out that it is easy to over fill the cell so be careful. When I hooked up the charger some of the stuff came out the top so I had to grab some paper towels to soak up the extra. I wasn't ready for that. Good luck with you're choice.

[Carnut]

My choice would be Optima also. You'll need to measure and check post placement.

I've used Optimas for years and have gotten nearly ten years out of the last one I replaced.

[dwattsup]

I've used the Optima in my boat (2 of them on a switch) and put one in my wife's Accord last year. No problems with them, although the one I installed in my wife's car was smaller than the stock battery. Not sure what the model for the GT500 would look like as compared to the stock battery. If I ever need to replace the battery in my GT500 I'm going with an Optima.

[VaporDude]

I still have the original battery in my car. I wouldn't ask the :monkey: about batteries, you know what his looks like. :grin:

I still have the original battery in my car. Fortunately, the deer strike didn't impact my Raptor battery either. :grin:

Thanks for the input....looks like I may sneak another year out of mine after all....I boot strapped it (not something I recommend or will explain...too dangerous if you don't know what you are doing) and then ran a few charge/discharge cycles and it seems to have bounced back :)

Although I don't have personal experience with this brand, I've heard Interstate batteries are very good...although they may not come in stock size/color, so they might look funny (they have some bright green on them).

This one just came up on the new posts.

After seeing the original post and the avatar I was going to suggest two heavy duty D cells, although some of the more dainty tools use 2 or 3 AA cells. Best to get rechargeable if used frequently. :)

P.S. I see the OP is in Canada. Are there metric batteries? What is the conversion?

I'm a little biased,but I would put in an Odyssey battery. EnerSys manufactures Odyssey batteries and markets them through distributors like Batteries Plus, West Cost batteries and many more. We also produce Sears DieHard Platinum, a line of batteries for Interstate, a number of other private labeled batteries and many batteries for the armed forces. EnerSys was the originator of the Optima battery years ago and sold that off, we now make high end flat plat AGM batteries that will outperform and outlast Optima. I haven't replaced my battery yet but always keep several spares in the garage. The original battery in my 07 SGT is a group size 97R but I have a Odyssey G48 waiting to replace the current battery as soon as it goes out.

I wind up using factory blems that I pick up for about $25 :salute2:, currently I have several sitting in my garage that I used to conduct packaging tests on our UPS shippable cartons and once done a few would up at home.

The 40R is the OEM size, it refers to refers to the physical size, polarity (R vs. L) and sometimes the recommended CCA/Ah rating. You can often switch to other group sizes as long as it will properly mount within the tray, cables will reach and there is enough clearance to prevent a shorting hazard. When I get back to work next week I will look at the BCI book to see what other sizes may work for a 40R. I know some of the battery sites will say that a G34R will work for a lot of the mustang applications but it doesn't offer as much clearance as I would like between the top of the terminals and the underside of the hood.

Thanks. I got one that was just about the same L x W... but was about 3/4" taller. Checked tonight... and it's right up against the d*mn hood. :banghead:

Mine had no issues either. I've kept the BatteryMinder on it at all times... until one of the kids unplugged it some time this fall without telling me. :doh: Once it discharged I couldn't get it to take a charge again. It was strong enough to run the radio/lights etc, but not enough CCA to turn the starter more than once or twice.

Why would your replacement battery be a different size?

I don't think I've ever run into that.

Why not?

[Joe G]

Why not?

:iagree:

It wasn't the 40R size, but store said it would work. Case size was fine, but the OEM has the terminals recessed - replacement one has the terminals mounted on top of the case, adding the 1".

[Tommy Gun]

Never got one a different size before?

[Highwayman]

It's time for another battery again. Just like the original one this one is leaking and has caused acid damage to the paint and possibly the tray and heat wrap.

I am done with these liquid filled acid batteries. Sooo.... how about some suggestions.

[Tommy Gun]

First have you kept tenders on them?

I’ve never had issues w overcharge/spillage w using a tender every now and then.

I’ve usually used Interstate as replacement batteries and a gel battery is gonna be twice as much money unless that’s not an issue.


I’ve had an Optima battery in my track car before and held up really well and they don’t leak.

[68fastback]

There's also a new type of battery I saw in one of the car mags (I think it was Muscle Mustangs and Fast Fords -- back home now so just looked but couldn't find the ad). It's not flooded/AGM and don't think it's a gel either (uncertain) -- and looks to be different shape in that it's about the same height and length as standard flooded battery but much narrower (looked about 1/2 the width) and weights only about 15 pounds as I recall. That was the first time I'd seen the ad and I don't know anything else about it but it caught my attention. The one pictured has 'standard' Ford/top-mount battery terminals and was being advertised as the ideal car battery b/c of the weight savings. Sounded a bit like magic to me unless someone somehow came up with a 'better' battery. If I see it again I'll post something.

[Tommy Gun]

:waiting2:

[twobjshelbys]

I'd think Optima is probably your best choice. It won't leak but even those have supposedly gone down hill in the past few years in that they used to last "forever minus a little" and now only go for as long as a usual lead-acid (3-4 years, depending on where you are).

[Highwayman]

All of our vehicles have battery tenders that maintain the battery.

The GT500 does not get used much.

[68fastback]

Mark, are you sure it was actually leaking vs built up a bunch of acid salts (like Mike's green battery crud) or belched out some acid from the filler vents?
Just asking b/c never had battery develop an actual case leak.

I don't know about the Battery Tender (Schumacher Electric), but I love the Battery Minder -- they make a bunch of different models (http://www.batteryminders.com/)but I love this basic one => Battery Minder (https://www.northerntool.com/shop/tools/product_200332201_200332201)(that's the cheapest I've ever seen it too!) -- it's somewhat unique in that it has a patented high-frequency anti-sulfation mode it automatically goes into after it trickle-charges the battery ...seems to make battery last forever by preventing sulfation build up on the plates. Sulfation can make battery plates 'swell' and short internally.

Actually talked to the developer and patent-owner years ago before I bought it -- cool dude ...very small company. Biggest problem they had is fending off the patent infringers. Only thing a little different with it is how you use it -- they tell you to connect it onto the battery first and then plug it into 120v ...has to do with reading battery condition before it begins to charge (only 1.3A max so not intended for deeply discharged batteries), then goes into the slow high-frequency anti-sulfation trickle charge which it can maintain indefinitely. It can even recover lightly sulfated batteries if they are otherwise mechanically okay inside (i.e. plates not distorted from over-charging with high-current chargers).

Awesome product, imo.

That's what I've used too. Still on 2nd battery - first one died because guys who were storing it for me in MN for a year during the move disconnected the Battery Minder by mistake.

That battery does look defective I don't know how they attach top and bottom ...may just be a specialized friction joint or maybe hot molded-on or something. Possibly overheating would do that? Would be interesting to know the specific gravity of each cell ...I'm thinking one cell may have overheated possibly due to a warpage/shorting issue.

The case to lid seal is generally heat sealed (melt/soften both pieces and then push them together) but can also be bonded with adhesive but that is typically not done on polypropylene materials. When using a chargers or maintainers you need to make sure that the charging algorithm matches what is recommended by the battery manufacturer. We have seem issues using a Del Trans battery tender on some AGM batteries because it doesn't charge at the correct voltage and causes the battery to sulfate.

[Shelby-Don]

I'm a little partial but AGM batteries are great, but no matter what chemistry you are using if your car sits for extended periods of time you need to either put them on a proper charger/maintainer or disconnect the battery when not in use.

I have an Odyssey Performance model group 48 in my car which is a little taller than the OEM G96R so I have a rubber insulator on my hood just to be sure the terminals don't touch the hood. We have prototyped a G96R model and should have them available within the next year.

When not in use I keep my battery connected to a Odyssey charger/maintainer.

[Tommy Gun]

You mention disconnecting the battery...personally I think much better to keep connected and on a maintainer. My point is for rust/corrosion protection. (Cathodic?) I think the light charge helps keep the metal surfaces in check.

Not sure if that thinking is correct or not in respects to a car, but heard it years ago and have always done it that way. :(

[twobjshelbys]

When in storage use a battery tender. Disconnecting the battery clears the learned emissions settings and will require a drive cycle to reset them. It's really annoying to go to the emissions test and find out you have to drive 200 miles.

[68fastback]

Mark, I'm wondering if 1.5A is too much current for continuous charging over very long periods.

One thing I like about the Battery Minder is it's trickle charge goes as low as 5 milliamps when it switches to anti-sulfation mode (when green light changes to blinking green) ...I leave it on the Ranger full time like that and that battery was already at least several years of use when I bought the BatteryMINDer and took that battery out of the old Taurus Wagon in 2011 when I sold it (put the old Ranger battery in the Taurus Wagon). It takes the standard Deltran polarized plug cables (like your Schumacher) so you can easily extend the cable. I also put the Tractor on it at the same time (I made up "Y" cable) over the winter now. The factory cable and "Y" cable both have 3A fuses (recommended) -- important to have when maintaining two batteries because, when you plug in a second battery after you used one item (car/tractor/etc), if there is more than 3A flow between them it will blow that fuse. However, it's easy to tell if that has happened by just plugging cables since there is a light indicating battery connectivity independent of 120V connectivity, so it's easy to check if any Deltran cable fuse (if doing two or more bateries) has blown -- but that should not happen (never happened for me) if you hook up a second battery after driving/using vs if one is fully charged and you just plug one in that isn't -- that WILL blow one of the fuses (standard mini automotive fuse).

Anyhow, the BatteryMINDer Owners Manual and a Spec summary for model 12117 are both on that Northern Tool webpage (https://www.northerntool.com/shop/tools/product_200332201_200332201?utm_source=bing_PPC&utm_medium=Automotive_Feed&utm_campaign=Feed&utm_content=12117&mkwid=T5SJJJGZ&pcrid=73736057608329&mtype=bp&devicetype=c&storeId=6970&langId=-1&type=search&msclkid=141fce3fdcfd16feb2f7948d58cc3763). That model (12117) has been discontinued for around seven years now (replaced by a model that costs twice as much -lol). The replacement model was just coming available when I bought the original but after talking to the inventor (who explained a bunch of stuff) I decided on the older (original) model because I can tell exactly what is going on and didn't need the enhanced features. The replacement (model 1500) has a microprocessor and added automatic temperature compensation which might be useful in Florida's heat, but since it they both 'trickle' down so low I doubt it's needed for maintaining (would matter more for actual charging) ...I decided I didn't need that.

[twobjshelbys]

My battery tender is one I got from Interstate but is branded as a "Battery Tender Junior" and made by Deltran. I bought it 10 years ago when I got the SGTs. Anyway, that particular model was more than a trickle charger. It would "disconnect" when the battery was at full charge, and then kick in again when needed. So on a long term it might be yellow (standby) or green (charging).

So at one point the Junior went into a mode where it couldn't be shipped to California. CA had implemented a general "only operate when charging is needed" law, meaning, it had to reduce power consumption if the battery was fully charged. In essence, behaving like my more expensive older model did.

Bottom line is you want one this a Battery Tender, not a Trickle Charger, but that a CA compliant Trickle Charger may in fact behave like a Battery Tender.

This explains it

https://www.theglobeandmail.com/globe-drive/culture/commuting/trickle-chargers-vs-battery-tenders-whats-the-difference/article1241701/

[68fastback]

That's why I like one that charges and then stages itself back to a variable VERY LOW maintenance (trickle) charge as low as 5-20ma -- based on how the battery took charge while it was charging. The high-frequency anti-sulfation is a really an important benefit too.

Just quessing, but CA probably has that law (shut off after charging, then restart, etc.) because they think it's wasting energy once a battery is fully charged, but that's nonsense since it still needs a very slight charge current just to not lose charge due to inherent charge leakage in all such batteries (just sitting with no load). They probably were reluctant to legislate a specific maximum maintenance charge level because they couldn't -- it's specific to the battery capacity and the battery's condition, so they likely just mandated it be turned off after the batter is fully charged, but that's just plain dumb because it will cause plate sulfation over time ...which can be prevented and actually enables the battery to better take and hold a fuller charge (and at a lower charge current) ...which then reduces the level of maintenance needed (hence the microprocessor and ambient temp sensing on some units to target that more accurately).

Leave it to CA to screw up something good -lol

[Highwayman]

But this one says it 'maintains' the battery by letting it discharge then recharges it. I thought that I had the right one.

I have one of these on all of the cars and motorcycles and the GT500 is the only one giving me a problem.

[Tommy Gun]

My tenders are like Dans, started using them in my Jetski days, then the ATVs, now the cars and motorcycle.

Charges, then switches to very lite trickle...actually, mine have a button for “maintenance” which goes quickly to trickle if the battery is already charged.

My tenders are like Dans, started using them in my Jetski days, then the ATVs, now the cars and motorcycle.

Charges, then switches to very lite trickle...actually, mine have a button for “maintenance” which goes quickly to trickle if the battery is already charged.

Yup, exactly ...and even if you don't press that button it figures out in just a few minutes that it's already fully charged and automatically jumps over to maintenance mode.

I'm a little partial but AGM batteries are great, but no matter what chemistry you are using if your car sits for extended periods of time you need to either put them on a proper charger/maintainer or disconnect the battery when not in use.

I have an Odyssey Performance model group 48 in my car which is a little taller than the OEM G96R so I have a rubber insulator on my hood just to be sure the terminals don't touch the hood. We have prototyped a G96R model and should have them available within the next year.

When not in use I keep my battery connected to a Odyssey charger/maintainer.


What's new for Odyssey AGM batteries? I want a little smaller size battery for my car... Still want the cranking and amp hrs... I have a Shuriken 1250 in the trunk for the stereo...

What about a small windmill. I hear Canadians love them. :rofl:

Is that to act as a deep draw current buffer ...but also tied to the car's charging system?

...Art, how about a horizontal wind turbine (https://i.ytimg.com/vi/2YCSfhcgSSs/hqdefault.jpg) in place of the rear spoiler :giggle:

[onecrazydog]

Exactly correct... As per usual!! :giggle:


It is tied into and charges off the main battery... I can crank the stereo and the charging voltage stays at 14.1, so it helps save the alternator too!!!

WindMEHlls... I prefer the smell of crude oil in the morning...

Besides, windmills kill more birds than my cats do...

Lol !

Cool! So I'm guessing it's sort of like a simple dual-battery RV system ...the second battery is isolated from the primary in that when the engine is off you could draw the second battery down without drawing down the primary but the alternator will charge both when engine is running. I had similar arrangement for the Quadravan refrigerator, if that's how this works.

[onecrazydog]

There is a power cable from the main battery direct to the trunk battery terminal, then a cable from the rear battery goes to the amp dist block!! They both would die at the same time...

[68fastback]

Oh, okay. :tiphat2:

Well almost...lol


“Wind turbines kill between 214,000 and 368,000 birds annually — a small fraction compared with the estimated 6.8 million fatalities from collisions with cell and radio towers and the 1.4 billion to 3.7 billion deaths from cats, according to the peer-reviewed study by two federal scientists”

.

[68fastback]

...but cats are supposed to kill birds :shades:

[The Bone]

Birds must be like ants. So many and they keep on coming LOL

What about lithium? I would probably have to change both batteries...

In true BCI size batteries with proper hold downs we will be releasing group sizes 47 & 96R soon and our next size will be a group 51. For smaller batteries we have PC680, PC925 AND PC1200 as well as some other sizes made in the UK but these do not include factory hold downs. We have a lot of race teams and custom fabricators that use these in tight spaces. Check out the Odyssey website at www.odysseybattery.com

[68fastback]

Don, that PC-1500 on the splash page looks like a beast ...has got to be real winner!

[onecrazydog]

The PC1200 could work... It's pretty close to the factory battery specs, but smaller!! I want a smaller one so I can run the wiring around it a bit better!!

A righteous well of power for your awesome sound system! :banana: ;-)

[onecrazydog]

Lots of reserve too, so I can get a smaller one for the front!!

[68fastback]

Cool! Then when you take the rear one out for the track you're lighter.

Seems like a win win to me!! I will probably get the same one JT put in his fox beauty!!
