Good Value for AGM Battery

Arrived on time. Fit was right for my generator. Charged it up and started the generator. I like that is was sealed AGM rather than lead acid.

Great price! Lawn mower started right up. Wasn't exactly the correct dimensions to install it on the mower but was able to add a piece of wood to hold it in place. Will buy the same battery again when needed. Thank you

Generac battery replacement

Battery fits the generator as well as the original. Connected float charger and was completely charged within 10 minutes. In other words, it came charged.
