1.0 out of 5 stars Failed within a year and a half, Optima refuses warranty service, August 5, 2009

This review is from: Optima Batteries 8004-003 34/78 RedTop Starting Battery (Misc.)

I bought this battery from a local Optima dealer on January 2008. It died on August 2009.

Since it comes with a three year warranty, I tried to get it serviced under the warranty by calling the Optima 1-800 number. Customer service agent was very rude and kept telling me I'd have to pay a fee in order to get my battery serviced.

5.0 out of 5 stars Cranking power!, January 14, 2009

Perhaps I just haven't had a new battery in a while and I've forgotten how they all work when new, but this battery seems to throw a LOT more power than I expected to the engine to start it up on even the coldest days so far this year. If this battery can perform at this level for a couple years, it'll have been the best battery I've ever bought. At this point though, expensive compared to the "el cheapo" brands you may find at walmart, but worth it knowing it's got the juice to get it done.

5.0 out of 5 stars worthwhile upgrade, December 22, 2008

By	rob22042 "BOBCAT BOB" (northern virginia) - See all my reviews

This review is from: Optima Batteries 8004-003 34/78 RedTop Starting Battery (Misc.)

Needed a new battery after 5 years and wanted something that would stay charged up since i don't use the truck every day. Spins the engine even on the coldest day like it was summer. Also have an electric snow plow lift that challenges normal batteries. So far I'm pleased with my purchase, came as advertised and took less than a week to get it.
