Powertran® M 8521A Battery C Maintainer 6V/12V 600mA
Operation Modes
Switch 1: 6V mode (6.9V +/- 2%)
• This mode is intended especially for 6V batteries.
• Having selected the mode, the charging process starts automatically (0.6A+/-10%), LED 4
is lit when the charging is in progress.
• When the battery is fully charged (6.9V +/- 2%), LED 4 light off. The device continues
maintenance charging.
Switch 2: 12V mode (13.7V +/- 2%)
• This mode is intended especially for 12V batteries.
• Having selected the mode, the charging process starts automatically (0.6A+/-10%), LED 4
is lit when the charging is in progress.
• When the battery is fully charged (13.7V +/- 2%V), LED 4 light off. The device continues
maintenance charging.
Regeneration function:
• This function is designed to regenerate deep-discharged batteries. It cannot be directly
selected, but commences automatically if needed. If a deep discharged rechargeable battery
is connected to the charger, the regeneration mode is the first mode to start. Low charging
currents are used to try and bring the deep discharged rechargeable battery to a normal
battery voltage again. When the battery reaches a normal voltage, the charger will continue
charging using the regular process. Even with a very low battery voltage of 1.5 V the device
starts charging. Therefore, deep-discharged batteries can be charged as well.
