Battery and charger
The battery pack is not fully charged out of the carton. First read the safety instructions and then charge your battery
according to the instructions.
For optimal charging capacity the battery should be charged at an ambient temperature between 18 °C (64 °F) and 24
°C (75 °F). To prevent damage to the battery pack, do not charge the battery pack where the air temperature is below
4 °C (32°F) or above 40 °C (104 °F).
To obtain the longest possible battery life, we suggest the following:
Store and charge your battery in a cool area. Temperatures above or below normal room temperature will shorten
battery life.
Never store the battery in a discharged condition. Recharge it immediately after it has been discharged.
All batteries gradually lose their charge. The higher the temperature, the quicker they lose their charge.
If you store your tool for long periods of time without use, recharge the battery every month. This practice will prolong
battery life.
Charging procedure
Connect the power cord to the charger, and then plug into an outlet before inserting battery pack. All three charging
lights will be on for two seconds and then turn off.
Insert the battery pack into the charger. The lights will start to flash within 30 seconds.
During the charging process, the charging lights will indicate the status as follows:
Three charging lights will flash in sequence during the charging process.
Fully charged, all three lights will remain on continuously.
The charging process will last approximately 50 minutes for BPA 10825 and 100 minutes for BPA 10850 battery pack.
NOTE! This charger can only charge Mirka 10.8 V battery packs.
NOTE! Charging times may be longer depending on the surrounding temperature and battery conditions.

minutes and re-insert.
