  • STM does not warranty batteries. We offer the STM Lifetime Guarantee on the STM Battery Tray, but we cannot warranty the batteries themselves and any attempt we have made to have them warrantied by the manufacturer has been denied. The typical life we get from one of these batteries varies from 2 to 10 years. Expect to treat this battery as a maintenance item - once it's done, just get a new one.

Am happy with this Purchase. I little Difficult to install since it is night and i couldn't wait till morning. But it started right away!!! And it honestly came alot sooner than i expected it to.

Good replacement

Only complaint I have is that there were no instructions with the STM bracket. The longer tie-down goes on the back side of the battery.

Buy it

Love it, not an eye sore to look at. Lighter, Smaller and more powerful. Why would you not upgrade.

Easy Install! Started Right Up.

Car was covered for the winter, had 11 years on the original factory battery and it finally gave out. Got one of these. Quick and easy install. Just have an alan key for the terminals. Started right up. Painless install. Except trying to fit my old a$$ into that tiny trunk 😄

Powerful lightweight

Amazing product guys no complaints at all. My old bulky battery went bad so why not try something new and better and let me tell u it’s worth it! My car started right up after installing it like a matchbox.
