From: eddie on 9 Mar 2010 18:16 if a battery needs replacement, assume any make/model of a car, how important is it to purchase the OEM battery or will any similar CCA rated battery, sized properly fitting into the battery case under the hood, be acceptable? when purchasing a battery from any of the larger national outlets, they always have a couple options where the CCA is precisely the same as the OEM battery but sometimes they also have a little cheaper (maybe for $20 less) model available that has a lower CCA rating. if the CCA rating does not match precisely the OEM CCA rating, what are the issues to consider? I understand that for winter and cold weather startup, the CCA can be very important but what about more moderate climate where there are no subzero temperatures? is there a universal rule that under warranty, only the OEM battery can be replaced with another OEM battery ?

Get a battery with the largest CCA rating available that will fit into the space. If your car is fairly old, batteries have improved, and you can get a higher capacity battery than the OEM one. This means the battery will last longer, effectively. >when purchasing a battery from any of the larger national outlets, they always have a >couple options where the CCA is precisely the same as the OEM battery but sometimes >they also have a little cheaper (maybe for $20 less) model available that has a lower >CCA rating. Do not ever get a lower CCA rating. Batteries get old, and they degrade, and you want one that can degrade as much as possible while still starting your car. An oversized battery is a win. >I understand that for winter and cold weather startup, the CCA can be very important >but what about more moderate climate where there are no subzero temperatures? If you have more capacity than you need, the battery can degrade more and still be okay, under any conditions. If you are in a place where it gets very hot, or a place where it gets very cold, you might investigate special batteries designed for those conditions also. >is there a universal rule that under warranty, only the OEM battery can be replaced >with another OEM battery ? Sheesh, if the car is under warranty, get the dealer to replace the battery on HIS dime. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis."

My experience with "bigger/stronger" batteries is that they don't last any longer then "normal" capacity ones. I buy whatever has the best combination of warranty/price. I don't think the warranty on the car will be affected by your choice of replacement battery, it would be a real stretch for the dealer to make any connection.

Batteries don't like to sit on a shelf.
From: eddie on 10 Mar 2010 07:47 thank you for all replies. the reference to warranty was due to a local dealer performing a recall/warranty service (toyota) and upon finding a non-OEM battery they claimed to owner that entire warranty has been voided. according to their words ".... the higher capacity/CCA battery has caused (components) to be fried... " there are no issues with the car, nothing is broken the owner is simply having car checked according to the letter where dealer adjusts as needed the acceleration related components.
