How Long Did Your Replacement Battery Last?

Recommended Posts

There is another thread in this sub-forum called "How long did your OEM battery last?"



I would like to hear how long your replacement battery lasted.


My replacement Duralast Gold lasted only 2.5 years, and I replaced it because it was getting too weak (probably due to sulfating of the plates). My charging system checks out OK, in terms of current output, voltage output, cables, and connections. My OE battery lasted 6 years, and I replaced it as a precaution due to its age, even though it still started the car in winter.

I think my Maxx Everstart has been in there 3 years. I'll check later and post the date I put it in.
