Fischer Amps ALC 161 Battery charger
The FISCHER AMPS ALC 161 Charger has 4 charging chambers for 4 AA or AAA batteries each. The new version of the ALC 161 has 16 separate channels. Each of the charging chambers is controlled separately by 4 micro
controllers. After inserting the charging box with the batteries into the charging chamber, a voltage measuring process detects whether the battery is extremely deep-discharged. In this case, the battery is charged in refresh
mode with a small amount of current until a voltage has been reached which allows fast charging. In fast charging mode, the status LED of the corresponding charging chamber flashes red every 2 seconds. A defective battery
which cannot be charged any more is therefore detected, because it does not reach the voltage required for fast charging. In case of battery fault, the status LED of the charging chamber flashes every second. When a regularly
discharged battery is inserted, fast charging starts immediately.
In fast charging mode, the status LED of the charging flashes red every 2 seconds. After a qualifying period for voltage stabilisation at the battery, the charging current is switched off for a short time and the voltage of the battery is measured. After approx.. 15 minutes of charging the controller detects if a AA- or a AAA battery is inserted and controls the charging current to 800mA for AA batteries and 400mA for AAA batteries.
When the charging processor detects that the battery is fully charged, the fast charging current is switched off and the battery is kept full by means of trickle charging until it is removed, while the status LED lights red with short OFF-impulses. The battery can remain in the charger without danger of overloading. When the batteries are not needed for a longer time, switch off the charger and reload the batteries to maximum capacity before use. This saves electric power and protects our environment
