This 4A Intelligent Battery Charger is perfect for maintaining and restoring your battery especially when it will not be used for an extended time. Such applications include: ATVs, Snowmobiles, Motorcycles, Watercraft (boats, jetski, etc.), Trailers, RVs, Ride-on Lawnmowers, Tractors, Classic Cars, Auxiliary Batteries, Back-up power supply, Solar Battery, and more!

Winter Mode helps to maintain the battery when the temperature drops below 41°F (5°C).

Fully-Automatic Charging 9-Stage Charger

  • Primary Evaluation is the first stage in which the charger runs a diagnostic test on the battery's condition, charge, and overall health.
  • Recovery charge is the second stage where the charger will begin to restore a deeply discharged battery. This step is skipped if the battery does not require it.
  • Soft Start action is applied to protect the battery and optimize charging, a slow charge current is applied to the battery then ramps up.
  • Pulse Cycle is initiated to help "knock off" sulfation build-up on the plates that may be inhibiting the battery's ability to reach full capacity.
  • Reconditioning Cycle helps to prepare the battery for bulk charging and finalizes the recovery charge.
  • Bulk Charging is the first stage in which the charger identifies the battery and its needs, then applies a high voltage/amperage charge to do the bulk of the charging.
  • Absorption Charging is when the battery has reached ~80% of its capacity and begins to lower the input current to the battery. This is sometimes known as the "cool-down" cycle.
  • Evaluation Diagnostic is the last diagnostic mode to ensure the battery is at its optimal health.
  • Maintenance Charge, also known as "trickle" or "Float" charge. The battery has already reached 95% so the charger will continue to apply a steady current until the battery reaches 100% capacity.  Then the charger will continue to monitor the battery and apply a charge if it detects any loss.
