Replacement battery

[JL for Life!! 10+ year member]

Im looking for a replacement cranking battery that will help with power to my amp (my lights are dimming). Optima doesn't have the best reviews online. Any suggestions? Also, I do plan on replacing my alternator and adding an extra power cell.

deka makes a gr8 product

but if your gonna run two batteries you can sacrifice some cca and use two larger agm style batteries (one in back one in front) xs power makes some gr8 stuff as well

if you do you must wire from ur alt to frnt bat then to rear batt ( also do a big three)

if you choose a larger (non agm) cranking batt up front and a agm out back, then wire from alt to frnt batt and then frm alt to rear batt (also upgrade grounds, thus completing big three )

good luck

Go with xs power

A new, quality battery will help some with lights dimming IF you're replacing an old, worn battery. Keep in mind, your car's electrical system is powered by your ALTERNATOR, not your battery. Try the big 3, if that doesn't help, your factory alt is probably a 90 or 100 amp and just can't keep up with your system's electrical demands.

I have been checking into the Odyssey AGM's...they look pretty solid, with good ratings/reviews
