Harley-Davidson Original Battery 66000209 20AH AGM for FX and FXR '73-'94, XL '79-'96, Softail '84-'90, FXR '99-'00

AGM (Absorbent Glass Mat) batteries is the most modern variant of the lead-acid battery.  

In it, the electrolyte is bound in glass fiber fleece. This results in low self-discharge, which means that recharging is only necessary every six months if the battery is not stored above 20° C.

AGM batteries are also capsize- and leak-proof, and they can be installed in practically any position, which is particularly advantageous for motorcycles.    

Another advantage is that, unlike gel, the fleece slows down the flow of ions significantly less. As a result, AGM batteries can be charged more quickly with stronger current than gel batteries and, due to the lower internal resistance, they can deliver correspondingly larger amounts of current to consumers if necessary.

Please note the above information: Fits Harley-Davidson FX and FXR models '73-'94 with electric starter, XLCR '77-'78, XL models '79-'96, Softail models '84-'90 and Fits Harley-Davidson FXR models '99-'00. Also fits Buell S2/T Thunderbolt models.
