The Auto Meter BEX-3000 Battery Extender keeps your battery at full charge on a continuous basis. Compatible with all lead acid batteries, this charger features fully automatic smart charging with advanced circuitry that enables energy efficient and safe charging via Auto Meter's advanced software.
Charging Modes
The BEX series chargers are fully equipped with sophisticated circuitry that will safely charge and maintain batteries without overcharging. Charging lights will tell you what stage of charge your battery is currently taking.

  • Desulfation - Features an automated desulfation mode effective for recovering and fixing a sulfated battery through the use of Auto Meters patented Digital Pulse Load DPL.
  • Bulk Charging - BEX chargers put the bulk charge back into the battery so it can move on to absorption and maintenance modes. BEX series charges do not force current into the battery, the charger makes available a limited amount of charge current to the battery based on its acceptance
  • Absorption Once bulk charging has finished, the battery itself determines how much charge current it needs to accept through the use of our exclusive smart microprocessors. This method provides one of the safest and most effective slow-low charging current available on the market today.
  • Maintain Maintains battery health by monitoring "state of health" and acts accordingly to bring up the charge if needed. The BEX units utilize Auto Meters award winning technology to automatically keep your battery in the best possible condition and extend its lifespan.
