My 1990 G60 is in really good shape. I solved a mystery battery draw gremlin in the power lock system, but the 3.5 year old battery is dead.
The car sits for two or three weeks between start ups, and has a simple Alpine head unit. No other ICE.
I'm in Philadelphia, so the winters aren't the harshest, but the winter temps will stay below freezing for weeks at a time.
I need a battery recommendation, before I buy another cheapo battery at advance auto or pep boys
