The Battery Tender Cigarette Lighter Adapter connects your Battery Tender battery charger to the cigarette lighter or 12 volt outlet inside your vehicle. Rather than using alligator clips to connect to the battery, you can charge the battery through the cigarette lighter. This method may be less messy and more accessible for some users, and it still provides the same safe battery maintenance.
The Battery Tender Cigarette Lighter Adapter works only with cigarette lighters that stay hot when the vehicle is off. The lighter must be energized when the ignition is off to charge the battery. Plug the Battery Tender Cigarette Lighter Adapter into the lighter and into your Battery Tender 12 Volt battery charger, which must be plugged into a standard wall AC outlet.
The Battery Tender Cigarette Lighter Adapter works with all Battery Tender 12 volt battery chargers.
