So, you may have read my dead battery post from a few days ago. If not, here's a recap. The winter(and my laziness) killed the Harley AGM battery on my bike. Killed it dead. Killed it so dead it didn't spark when I accidently touched a wrench between the + terminal and a bare spot on the frame. I wasn't surprised it was dead. It was new in '01, I got it used for free in '02, and I don't ride this bike all that much so it spent alot of time sitting. Well anyway, being a cheap bastard, I wanted to see if I could avoid buying a new battery. So I threw it on my 10 A charger. At first, it wouldn't take any amps, and volts were still very low. But I let it sit on the charger anyway. Much to my amazment, it came back. after only a day on the charger, it was up to 13.4V and holding a charge. Harley AGM's rock

I'd be willing to wager that the HD battery (like most all batteries now a days) is made by Yuasa.

Harley batteries are made by Deka and, yes, they are excellant.

sometimes if they arent taking a charge you can add some new fluids to them.

AGM (absorbant glass mat) batteries available from PowerSource. Get your H-D size here: http://www.lynnvickproducts.com/ps/app_hd.htm

The distributor is Parker Yamaha out of AZ: http://www.parkeryamaha.com/index.asp?PageAction=VIEWPROD&ProdID=25739

Good folks, helpful too. Call 'em or order online. Ships normal UPS ground w/ no 'hazardous' issues or the co$t associated.

I run small 4 amp jobbers in my kick only Knuck and Shovel bikes.

Highly recommend these batteries. But, then again, what do I know.

AGM's have no fluids, its like jello and sheets of fiberglass all wrapped up. deka's are tough, i've seen them personally ripped open and still holding voltage near the 70% charge range. when we swapped to them in the racecars, we were convinced after seeing photos of military choppers with bullets piercing the cells and the pilot never even recieved a low voltage warning light. like you really need a warning light in your eyes when someone is shooting at your helicopter.....

the chemical reaction process has a lot less losses than a typical lead acid setup, so the shelf life if properly cared for is pretty long.
