Mighty Max Battery YB9A-A GEL - 12 Volt 9 AH, GEL Type, 130 CCA, Rechargeable Maintenance Free SLA AGM Motorcycle Battery

Had to do some research and measurements, as I couldnít find if it was made for my particular bike. Iíve noticed that other batteries that have been tagged as designed for my Vulcan 800a are actually incorrect, having the battery posts in wrong position for the connections. Not this battery. Positive post is on the left side, as it needs to be. Also, the posts are much more robust than most other battery manufacturers. I liked the options of either vertical or horizontal mounting positions, as it actually gave me another mounting point to add my battery tender wiring. Speaking of which, itís highly recommended that you keep an automatic battery maintainer on the bike whenever youíre not using it. As I found out (and the reason I had to get this battery so soon after buying a different one prior) is that these AGM/Gel batteries will become damaged if allowed to discharge over time. I guess if you rode daily it wouldnít be an issue, but if you only take your bike out a couple times a week or less, it definitely pays to have a maintainer attached. Iíve had this battery for a while now, and itís started the bike up with no problems. I love that itís also a bit more powerful, with higher CCA than what I could get with a flooded cell.

Bought this to use in a 1980 Kawasaki KZ440 A1 and I'm quite pleased with the performance so far. The fit is good and it cranks the bike strong. Don't know if it's as hardy as a standard electrolyte battery, but it does seem to require a lot less maintenance.
