Perfect fit for 2007 Yamaha VX Waverunner
Bought this battery for a 2007 Yamaha Waverunner. It was a good price compared to other online and local stores. Upon opening the box, I put it on a charger to be sure it was fully charged and it was. It fit in the battery housing perfectly and the PWC fired right up. No surprises and it worked perfectly.

Decent, cheap battery for my old Honda CB350
Havent had it installed very long but topped off the charge and the old CB350 Honda fired right up. Would have no qualms about buying another especially at this price. flexibility for top or side post mount is nice, and the terminals have a little relief, so its less annoying to install the terminal screws. Size seemed a little small, but there may also be some missing rubber dampers in the battery box. Its a very messy bike. That said it fits great, and Id buy the same again.

Perfect fit!
I purchased this to replace the battery in my Champion Generator. I measured the original and checked it against the new one. Perfect fit and same amps and voltage. I installed it and my generator started just as normal. Good fit and fast shipping.

No response on warranty, Second battery to fail in under 6months on different machines
Junk, I have two unusable batteries. Bought one a while back it failed and would charge but not have enough power to turn over machine after a few months. Second one was purchased in January and I have had the same issue on a different machine, I have tried to contact the manufacturer twice on their site and have not received a response to honor their warranty. I had to buy another battery that has worked flawless. I would still like the manufacturer to contact me I don’t like being ignored and if you say you are going to back your product I expect you to do what you advertise.
