Odyssey Battery, Extreme Series, AGM

Bought one of these on 1/23/2013 for my 2005 Kawasaki Concours. About 5 years ago I left a switch on and drained the battery. I bump started the bike and rode it around and the battery was fine. On 10/24/2023 my bike would not turn over enough to start. I bump started the bike and rode it very far but the battery would not charge enough to start the bike. Shows 12.10 volts but not enough strength to start my 1000cc motorcycle. Since it lasted over 10 years it seemed like it was an amazing battery. I ride all through the winter but the bike has sat for a couple of weeks. Still starts right up. I ordered in the evening of 10/24/2023 and it arrived 10/26/2023, free shipping without Prime. I'm very happy with this battery and the company selling it.

I expected better from an Odyssey Extreme Series battery, especially given the brand reputation and price point. The battery arrived well-built, with solid terminals and a compact AGM design that should be convenient for applications where space and vibration resistance matter. Unfortunately, the actual performance did not match those expectations. I had trouble getting dependable service from it, and a battery in this category should provide consistent starting power without becoming another item to troubleshoot. For a premium AGM battery, reliability is the main reason I would spend the extra money, so poor performance is difficult to overlook. The physical construction seems good, but that does not matter much if the battery cannot be depended on. Based on my experience, I would choose a different battery rather than purchasing this one again.

Works great in our 2002 Gold Wing GL1800, no complaints so far.

Usually I have good luck with Odyssey Batteries. I ordered this one in April of last year. I finally took it out of the box yesterday, charged it and put it in the bike. First start attempt it cranked, no start. Then, there wasn’t enough energy for a second attempt. Hooked up the charger again and it indicated that the battery will not hold a charge once charged. Hooked a different charger/maintainer up to it and it DID NOT say the battery was bad, so I’ll give it a shot after another full charge. If it was in the return window I would return it just to be safe…..but…..

Fits my R60/2 modified BMW 🎉

Do not buy an Odyssey battery. I have owned their batteries for many years but this one was purchased on April 15th, 2025 and on December 18th it was dead. Odyssey has a 4 year warranty on this battery but to date I have not received a reply from them on this defective product. If they would honor their warranty I'd reconsider their product as I've always had good luck with the batteries.

Pensé k tardaría más en descomponerse solo lo e prendido dos beses y hoy lla no aranci y batería mala

Arrived in open box, damage on one corner from a fall, cap was open. The company responded and we made a suitable deal. Good product but shipping caused damage.
