I am on my 4th year with this battery. I have over 275 hours on my PWC (2006 Yamaha FXHO) and this battery is still going strong. I may replace it at the end of this year just to be on the safe side, but I will definitely buy another one. The lead/acid batteries I used in the past needed to be replaced every other year due to leakage or failure. This is a great battery for a PWC.
