The sulfuric acid used in car batteries is very dangerous to handle. If you can find a source, you may get lucky and replenish the battery with it. But, for me, I’d just consider this battery toast and simply replace it.

Understanding the Context

I don’t have the equipment to handle battery acid safely and it is just not worth it to me considering the very dangerous potential for human and property damage. Some of ... These batteries last a long time if properly cared for, meaning you keep water in it. If they don’t get water, the level drops below the plates.

Key Insights

These plates dry out and shed the electrolytes attached to them. Once the shedded material fills up the bottom of the battery they will short out the “cells” one by one. I buy all my car batteries from Walmart. Their prices are usually the best in my town, and the return policy works at any Walmart. I’ve only had to return a bad Walmart battery once or twice, but both times I was thankful for the warranty.

Final Thoughts

I got an AGM for my last car. I know there are premium batteries like the Concord and such but was curious if there are any run of the mill wet cell batteries that are better than the others. I always buy the premium or gold grade at the parts store and usually don’t have any issues. I have run through several of the Everstart brand gold models from Wal-Mart and know several others with similar complaints. I looked at ... I had bad luck with Kragen auto batteries that I moved to Kirkland and been using them.

A Costco branch I went to said that they only have Interstate 42 months warranty batteries - Kirkland used to be 100 months warranty. On a hindsight, you would think that batteries are getting better but …? Are Interstate 42 month batt. good replacement for Kirkland?
