Dodge: Battery CCA, cold cranking amps, warm climate

Question
Hello:

I have what will probably sound like a fairly ignorant question, but since I don't know the answer, I need to ask someone.  I will be replacing my battery.  The recomended CCA's (cold cranking amps) for my car is a minimum 340,(4 cylinder car 2.2 liter engine) I have moved from Virginia (Warm climate) to Chicago (Cold climate), and since then have had some problems starting, and have had to charge the battery several times. So, I would l;ike to get a battery with a higher CCA. My question is, if I get a battery with a significantly higher than recomended CCA, can it do any harm to my electrical system?, IE. overload it, or does the alternator have to work harder to charge it, and perhaps need to be replaced sooner?

Thanks for your time, and please forgive the simpleness of this question.

Regards,

Morad

Answer
Hello Morad,
This question is not ignorant,
Batteries have to work harder in cold weather,The alternator will keep the battery charged,and will not harm the system with a battery with higher cranking amps,Although you will need to refer to the owners manual to find out what the max. cranking amps are or visit an auto parts store and let them know what the problem is with the battery.

Never think a question is stupid,You never know the answer until you ask!You're Welcome..RamMan
