Brand: OptiMATE Battery Chargers
This special charging harness is designed to work with Optimate battery chargers. It plugs into your cigarette lighter socket or 12 volt DC power port for easy battery access without opening the hood. It even has a special built-in battery status monitor! The 2-pin SAE plug matches the plug on Optimate chargers, letting you quickly plug in the charger for maintenance.
The 4-LED battery status monitor indicates resting battery voltage when parked as well as charging status when the engine is running. The LED blinks every 3 seconds to minimize power draw. Suitable for use with any 12 volt lead-acid battery (AGM, gel cell, or standard). You can even use it without a charger if you only want a simple battery monitor.
The SAE plug is polarized to prevent reverse connection, and an inline fuse provides additional protection. Complete kit includes harness with fused DC cigarette lighter plug and a tethered dust cap to protect the disconnected plug.
Note: For battery charging using Optimate battery chargers only. Not for use with any other brand. Not suitable for boosting or jump-starting.
