Battery Tender brand battery charger harness fits most battery chargers on the market with the quick disconnect fitting. Also fits Optimate harness accessories. Harness is made to be left on the bike, so the battery charger can be connected without actually accessing the battery. Approximately 18 inches long. Also useful for a power supply cord for USB connections, cigarette lighter connections, and power outlets. Harness has ring terminals for attachment to battery, an inline 7.5A fuse to protect against shorts, and a standard 2 pin quick disconnect as used by many brands of battery chargers including Battery Tender, Parts Unlimited, and YUASA.
Nice to have these on all motorcycles, ATVs, snowmobiles, lawn mowers, watercraft, etc.
