Having problems with your 2001 Ford Focus ?

Battery replacement confusion!

\015 I am replacing my original Ford Motorcraft battery, as it no longer holds its charge after a few days and is now 8 years old.\015\012It is rated at 12V, 500A cold-cranking, 53 AH capacity. I am having trouble matching the capacity, so I may have to get a more powerful one, such as 590A 65AH, rather than a weaker one. However, is there a danger that the car's charging system may suffer from overload with a more powerful battery? The Ford manual says that the spec. should match that of the original, but a new Ford battery is more than double the price of other brands!!!\015\012Also, the Ford manual stresses that the battery MUST!! be lead-CALCIUM, as is indicated on the Ford battery with ''Ca''. However, I do not see any mention of calcium on the range of well known brands of batteries available at retailers.\015\012Any comments are welcome, as I am confused.\015 Posted / edited by AnonymousUser on : 14-01-2019

Answers :

I am confused too. Are you sure it didn't say lead-cadmium battery??? In any case you can buy any battery off the shelf that is a 40R series. The size of the housing and the location of the terminals should be the same as the battery you are replacing. Having a 590 CCA battery versus a 500 CCA one just means you have more power in reserve for cold weather starts. Check with your local auto parts supplier, Wal-Mart, or Batteries Plus for prices. Don't waste the money going for an 84 month battery. A 60 month will do just fine, and the only thing you are buying with the 84+ month battery is a SLIGHTLY better replacement policy.
It won't hurt your alternator if you put in a bigger battery. Never go to a smaller one. Remember to measure the battery box , including height,to be sure the new battery will fit.,
\015\012 I can't un derstand why the make up of the battery would make any difference to the charging system. Perhaps you should checkat the auto parts store for some input. If there was a specific reason for a lead-calcium battery as opposed to any other one they should know. They wouldn't want to pay out warranty claims for something if they don't have to.
