Looking for a lithium battery for my weekend / track car, do we have newer options in the last few years?
right now I am running on a Yuasa NP17-12I Industrial VRLA Battery 12V 17Ah, it's cranking car weakly since the beginning, sometimes cranks fine but not enough power if engine off for 10-15 minutes, while recovers it's power in an hour or so if car is left off for that time..so simply not enough power and not reliable for 3.2L boxster.
I am looking for this
UNIBAT Lithium 12Ah 720CCA which is for BMW bike for example
