Backup Battery Maintenance
The tool includes an internal backup battery. The backup battery is used, for example, to keep the radio communication active during exchange of the main battery. The backup battery gives approximately 30 seconds to exchange the main battery, before the tool shuts down.
Replace the backup battery at least every 12 months. The replacement procedure must be carried out by a qualified service technician. A replaced backup battery is to be recycled according to the Recycling Instruction.
Storage Conditions
The backup battery lifetime is negatively affected by extreme temperatures. Store the tool in an environment with an ambient temperature between 0 - 30 °C. Do not keep spare backup batteries in storage.
If a newly manufactured tool is to be kept in storage, make sure to power it up for at least four hours before putting it in storage.
While in storage, make sure to power on the tool at least every five months to recharge the backup battery. The tool must be powered on for at least four hours each time.
