Hey guys , just few questions. Can I buy a Wal-Mart battery to replace the original one, seen a suggested H8 900 .ca. Seemed to work. Also can someone please direct me on the after install procedure as far as needing to clear codes or resetting this or that?? This car is pretty complex on everything when your just learning the layouts!! Lol. All is appreciated!!!

This is what I did.

Yes, any battery that is of the same category can be used. Don't overthink it, pull out the old battery and install the new one. Remember to hookup the battery vent cable if you have one. If you have VCDS, you can code in the new battery; i didn't the last time I changed mine and there's no issues.

I'd personally go with this one and use a coupon code:

Big thanks!! To you guys. I grabbed an everstart maxxx h8 900cca at Wal-Mart 119$ with breather hose vent and it works like a charm. Found out the car will "learn" the fix autonomously in time. Good deal guys you guys are awesome!!!
