Quick guide from the manual
This document provides essential operating instructions for the Bosch AL 18V-44 and AL 2x18V-88 battery chargers. These chargers are designed for Bosch Li-ion batteries and POWER FOR ALL system batteries (PBA 18V type). Ensure the mains voltage matches the charger's rating plate before use.
Charging process
The charging process starts automatically when the charger is plugged into a mains socket and a battery is inserted into the charging bay. For the AL 2x18V-88 model, both charging bays operate simultaneously and independently. Charging is only possible if the battery temperature is within the permitted range (0–45 °C).
Wall mounting
The charger can be used free-standing or mounted on a wall using round-head screws (5 mm to 6.5 mm diameter). For the AL 18V-44, drill two holes with a 56 mm clearance. For the AL 2x18V-88, drill two holes with a 168 mm clearance.
Troubleshooting
