Sealed Ge Battery Requires Constant Voltage Charging

  　　A sealed Gel Battery, called "gel battery", is a sealed battery containing an electrolyte gel that reacts with the lead plate. Generally, gel batteries have a longer service life than sealed lead-acid batteries because of their sulfate resistance. Charging gel batteries with lead-acid chargers is risky because gel batteries require constant voltage charging compared to the cone charging provided by lead-acid chargers. This can be done if you closely monitor the charging process. When trying to charge a gel battery with a lead-acid charger, you must ensure that the peak charging voltage does not exceed 14.7 volts, which will result in a dry, non-conductive gel.

  　　step 1

  　　Connect the lead-acid battery charger to the Sealed Maintenance-Free Battery, connect the red cable to the positive terminal, and the black cable to the negative terminal.

  　　Step 2

  　　Switch the charger set to 2 amps / 12 volts, also known as a deep cycle. It is important to set it to a deep cycle to imitate the charging characteristics of CVC (constant voltage charger), which is a charger designed for deep cycle gel battery charging.

  　　third step

  　　Switch the charger to manual instead of automatic. Keeping it in the automatic state will cause the charger to gradually reduce its voltage because it will sense that the gel battery is fully charged. This cannot mimic the type of CVC charging required for gel batteries.

  　　During the 7 to 12 hours of charging, monitor the battery closely to ensure that the voltage output reading on the charger does not exceed 14.7 volts. In addition, please monitor the battery power reading of the charger. After reaching 95% of the battery capacity, please remove the charger.
