Battary Recomendation

[Tree]

Time for me to get a battery and I am not sure what I need for my Gen III coupe with a gen 2 coyote. I will probably put on a battery tender but I still want a battery that is okay not getting fired up all the time. Any recommendations? Thanks.

Every one I build gets a plain old lead acid battery from Autozone or Interstate. Shut them off, walk away for several months and they’ll crank when you come back. It’s no secret what my opinion is on Optimas but the debate will probably start again...

Go with an Optima, it will make Jeff so happy!

If you want a vintage looking modern battery, try these. I have one in my Cobra

Feel free, just understand that if you bring it to me for paint you’ll be required to bring a charger

Not going to get lost in the Optima discussion. You'll get lots of personal experiences, both good and bad, with nearly every brand. Pretty good chance one claimed to the best ever and another claimed to be no good are the same brand from the same factory. There are only a handful of actual manufacturers and a whole bunch of private labels. My advice is go to one of your local automotive chain stores (Autozone, Advance, whatever) and get one that's the right physical size and the best warranty. That way if there's a problem you have a local carry-in resource to resolve. Don't get too lost in capacity, cold cranking amps, etc. Our cars don't have nearly the electrical demands as the typical DD and we usually aren't cranking them in extreme cold when the cranking amps really start dropping off. FWIW, I put an Odyssey PC925T in my Coupe. https://www.odysseybatteries.com/pc925t.htm. Only rated at 380 CCA, but spins the Coyote like a top.

You'll also get lots of opinions about off season charging. I personally don't see any downside hitting it every month or two with the right charger. I've always done that and like the CTEK brand. But there are plenty of others. Some EFI systems, plus maybe other devices, can have some parasitic drain. Even if a very low rate, can drain the battery over time. Regardless, an occasional diagnostic charge is cheap insurance and saves any surprises when you're ready to start driving again.

Anyone using lithium batteries? I've used a couple in kit planes and they have some advantage: small size, very slow to discharge in storage, light weight,etc.

I have a standard lead acid battery that is the same one I installed 10 years ago. I put the charger on it a couple times over winter, just to keep it topped up, as the car is stored from November thru April.
