Hi everyone, was curious to know about car batteries, and if they aren't failing or straining to start the car...should it be changed? I looked at the stickers on it, and think it may be 10 years old. The car turns over well, the headlights still shine bright.
should i just wait till it craps out?
it's an ac delco professional series.
thanks

I changed my 12v battery proactively on year 9. I did not want to get stranded in the worst time possible like weekend evening or away from home. Also, I saved money by shopping around in advance and avoid paying last minute full price. I may lost 1-2 more years of service life left but I made these $20-40 value back on the new battery price discount.

On the other hand, my wife’s car battery failed in my garage during business hours, on a day I was home, very conveniently. A quick trip to the store to bring one and car was running within an hour.

 

10 year old battery? Unless you were keeping your car on battery tenders, I do not think you can get 10 years out it easy, jm2c.

 

Wow, ten years on a battery, I'd be fixing to swap battery's very soon....

 

Why don't you take the car to an auto parts store and ask them to check the battery? They do it for free. I had my battery checked at Batteries Plus for free.
