Money well spent

This battery is worth every penny. Just buy it, you won't be disappointed. We have a remote start on our conversion van that is parked outside in Minnesota. -10 degrees and it starts strong with absolutely no hesitation. I'll never buy anything else again.

awesome battery

Great buy would buy again in the future but it will probably last longer than the truck.

Optima Red Top Review

Super easy battery to install. The cranking power to my 6.6L Duramax increased considerably. Couldn't be happier.
