Troubleshooting - Hilti SFD 2-A Operating Instructions Manual

NOTE
– A conditioning charge (as is required with NiCd or NiMH batteries) is
not necessary.
– Interruption of the charging procedure has no negative effect on
battery life.
– Charging can be started at any time with no negative effect on battery
life. There is no memory effect (as with NiCd or NiMH batteries).
– For best results, batteries should be stored fully charged in a cool
dry place. Storing the battery in places subject to high ambient
temperatures (e.g. at a window) has an adverse effect on battery life
and increases the rate of self-discharge.
– If the battery no longer reaches full charge, it may have lost capacity
due to aging or overstressing. It is still possible to work with this
battery. You should, however, soon replace the battery with a new one.
