The ServoCity 12V Battery Charger (NiCad/NiMH, XT30 Connector) is engineered to efficiently charge 12VDC NiMH batteries. It features a smart charging mechanism that initially delivers a 1.0A current, which reduces to 0.07A upon reaching full capacity to prevent overcharging and maintain peak voltage. The charger is equipped with an LED indicator that signals charging status, turning red during charging and green when complete. It is essential to remove the battery once fully charged to avoid performance degradation.
