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 20 seconds to exchange the main battery, before the tool shuts down.

Always connect a newly manufactured tool to a main battery and power it up for two hours to charge the backup battery.

When using software versions prior to the versions listed in below table, 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.

With software releases according to below table, replace the backup battery every third year. The increased service interval applies to a fresh battery used only together with the software versions in below table. If the backup battery already is close to 12 months old, it is recommended to replace the backup battery when updating to the new software.

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 two 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 two hours each time.
