Optima vs XS Power Battery
 

Looking for any input on optima vs XS power batteries for super stock car. Also open to other suggestions.

Re: Optima vs XS Power Battery
 

I have only used the Optima and Interstate AGM batteries and I have had good luck with both.

I just purchased a XS i was looking for something that had starting power and deep cycle, and D925 offered both.

Re: Optima vs XS Power Battery
 

Any initial thoughts on the XS battery? Also what battery charger are you using with the AGM battery?

Re: Optima vs XS Power Battery
 

Which Optima battery have you used? I had a red top but looking at a yellow top for a deep cycle battery. Also what battery charger did you use for the AGM batteries?

Re: Optima vs XS Power Battery
 

We strictly use the Red Tops.

I have always used yellow tops. They starting batteries as well. I have used battery tender and Schumacker chargers. The key with an optima is to not exceed 14.8 volts when charging. They will taken any current you throw at them but over voltage is a killer

Read through this thread also. I suggest Odyssey batteries.

If you are talking about 16 volt batteries, I'm not a big fan, you can't just go in a parts store and buy 1 and the 16s take a special charger just my opinion.

Currently I am using a yellow top Optima for my ignition and an Interstate AGM for everything else, starter, fuel pumps, water pump and fans. My car does not have an alternator.

Before for many years, I ran a red top for the ignition and and a yellow top for everything else. They both lasted a long time.

My son has worked at and now manages the local Interstate Batteries dealership for over twenty years.

I really don't remember his rational in going to the yellow top for the ignition but I just followed his recommendation. He has a car he runs in Hot Rod's Drag Week and even though it has an alternator he runs a yellow top Optima in it. If you are interested in why he chose the yellow top for my car I can ask him about it.

I charge the batteries with a Black and Decker "smart battery charger" that has an AGM setting.

However at the track while I am charging the accessory battery with the Black and Decker I will top off the ignition battery with an ancient Craftsman 10 amp charger.

I will probably purchase another smart charger to use at the track. In a perfect world I would like one what would independently charge two batteries.
