Craig,

glad to help!!

My P250 handbook specifies a Urania Mc4b-12V-55Ah battery. Nothing on CCA ... If you won't be driving the car very regularly, from what I know I would recommend getting a good trickle charger (for example, try the Battery Tender brand) to prolong the life of your new battery - typical batteries don't tolerate very many full discharges well. Some folks also run Marine Deep Cycle batteries for this reason, but you have to make sure you have the CCA to start the car (and decent reserve is a good idea).

So ... can you tell us about your car? Got any pics? :-)

Regards,

Bryan
