The AIRBATT Powercharger series includes chargers that are built in primary clocked technology. Unlike conventional chargers with a high alternating current, the AIRBATT Powercharger series has an absolutely constant DC current, which makes the battery more even, more efficient and faster.
After full charge, the battery can remain connected to the charger. When the charger is switched off, a return current of 0.12 mA can be neglected. However, it is recommended to remove the charger from the battery during extended periods of standing (during the winter) as this increases the battery life.The AIRBATT Powercharger DUO 2641 PB contains two separate chargers in a housing for lead gel, nonwoven or LiFePO4 batteries from the manufacturers AIRBATT and VISION.
Maintenance-free VRLA batteries should always be fully charged, as this will extend battery life.
