John’s Auto Care Auto Tips and Videos: Battery Testing

The simple fact is that 70% of car batteries fail within 4 years. They just need to be replaced when they are no longer able to hold a full charge.

Batteries are a big ticket item for most Boulder drivers and it’s tempting to put off buying a new one as long as possible. But a battery that cannot hold a full charge requires the alternator to work extra hard, causing it to wear out prematurely.

Your John’s Auto Care service advisor can test your battery to see if it should be replaced. Testing is a good idea for CO auto owners because a battery might still be good, but become dead because of a bad alternator or even a worn serpentine belt and tensioner.
