Harley-Davidson Road Glide Battery Chargers

The 1 A maximum-current choices are 66000305 for the UK and 66000308 for Europe and the Middle East. These regional labels matter even when the product names look alike. Check the version for where you will use it, regardless of the language you shop in.

The chargers offer 6 V and 12 V capability; use only the voltage and battery-type combination approved in their instructions. Check the fitted battery’s charging-current requirements before choosing either rating.

Choose 66000310 for the UK or 66000313 for Europe and the Middle East if the battery’s instructions permit the 5 A rating. A higher maximum current alone does not establish a suitable charger or a charging time. These versions also offer 6 V and 12 V capability, subject to the approved voltage and battery-type combination.

The 5 A versions add an AGM repair feature. This is a manufacturer-listed function, not a guarantee that a worn or damaged battery can be recovered, and it is not a lithium charging programme.

The four chargers can use existing H-D charging cords. That describes compatibility, not which leads are supplied with a new charger. Check the connection already on your bike and the exact charger’s contents before ordering any additional lead.

Extension 99821-09 adds 12.5 ft of reach; 99828-09 adds 25 ft. Both use two-prong quick-disconnect connections and are listed for most H-D chargers. Check the charger and connector compatibility before choosing the length. Each is sold as an extension lead only: it is not a charger, a mains plug adaptor or a complete battery harness.
