    I can’t speak to longevity because I just got it, but arrived within a couple of days, fit perfectly into my Troy-built XP 700W generator, and fired right up. Seems to have the same cranking power as my original OEM. Great value for the $; unless of course it dies within a year or two. NOTE! When ordering, pay close attention to the orientation of your POS & NEG terminals. It’s not hard to mess up, order the wrong one and your cables will not reach. This reverse polarity has the POS on the LEFT. Worked perfectly for my machine.

    After 4 years the battery in my Troy-Bilt generator finally died. I found this battery on and it fit just the same as the OEM battery. The only issue I had was not the fault of the battery, but of the installation of the battery. I had several scraped knuckles before I got it installed. After the installation was complete it started on first push of the starter button. 2 thumbs up for this battery!
