Handling Precautions

Always attach the battery terminal cover.
Do not allow any metal objects to touch the terminals (Figure 1), as this can
cause a short circuit and damage the battery pack. Attach the terminal cover
whenever the battery pack is not being used (Figure 2).
The battery terminal cover has a [ð]-shaped hole. This is useful when you
wish to differentiate between charged and uncharged battery packs. For
example, with charged battery packs, attach the terminal cover so that the
[ð]-shaped hole shows the colored label.

Remaining battery time
If the remaining battery time displayed is not correct, deplete the battery pack completely and then charge it fully.
Still, the correct time may not be displayed if a fully charged battery pack is used continuously in high
temperatures or is left unused for long periods of time. Also, the correct remaining time may not be displayed,
depending on the battery life. Use the time shown on the screen as an approximation.
