New Battery Recommendations?

Recommended Posts

Group size is 48. Try to get at least a 700 CCA or better yet 850 CCA.

There is another thread here on the Optima battery. You will need to modify the holddown if you go with Optima. I think a better fit for 996 is the Optima 34R which put the battery post on the right sides and doesn't require any cable rerouting or changes.

Hello chicagobob,

I have the same car 99'C4, and my question is what type exactly you have mounted.

The type that has told Loren, 34R is not available in Spain, here we have in RedTop and YellowTop the 4,2LS and the smaller 4,2LU.

I don't use the car sometimes in 3 or 4 weeks, and have some electrical devices that don't disconnect.

Sometimes I can't starter the car after this times and the batterie is dead.

I'm thinking about to use the YellowTop cause she is developed for deep cycle.

My question is to search what dimensions is the Batterie you use and know if the YellowTop equivalent in Spain has the same.

Thanks in advance.

Thanks chicagobob, but this type of connectors are not delivered in Spain. I see that the general dimension of the type I need are OK. The only problemm is that probably I must change the + car cable, cause it's probably to short. I must check it.

Good speed.
