There batteries cost a bit more than lead acid but they last longer and perform better based on my 13+ years using them

Waste of money.
Bought this battery for my Ford F150 . The first really hot day of the summer, the battery failed. Tried recharging it and turns out the battery was defective. Optima use to make great batteries, now they just make junk. Really sad.

Buyer Beware
Buyer Beware seller will not send a replacement or refund for a defective battery. Used only for 9 months and now the battery is dead. Was told to contact a local supplier. What a great customer service.
