step 1 in getting my ptroject moving again
After a long break, I needed a new battery to get my bike project moving forward again. Bought this Mighty Max battery and was glad to see it was nearly 13V right from the box. Fit was good in the bike, and b/c the carbs were all empty it took a while to get it turned over, but the battery never gave up. I cranked on it off and on for a while and it never got too low. Always rebounded great from key on to key off. Finally the gas got moving and it turned right over. Idled for a while, and now I have plastic to put on. Do like me: overcome your laziness and get things ready to ride again. Getting a new battery really got this project to the finish line and got me in the mood to get riding again!

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.

Great Price - Fast Shipping
Great Price for a nice AGM battery. As with this battery, most don't come with much of a warranty. If you have about 30 spare minutes, you can review the warranty requirements!
