I'd recommend this battery to anyone.
Holds voltage like no other. Have not had to charge it yet (after 1 year of everyday pounding on a stock alt). It holds 12.6 after days of sitting, and I don't let the alt charge it before i park for more than 1 min and I only do that because i don't want to attract attention in my hood, not because the battery needs it!

Do some research on XS power if you still have any doubts and you'll see they have become the #1 choice among car audio fanatics.

Plan to buy another XSbattery or two for my next build!
