When to recharge
E
You can recharge a lithium ion battery pack whenever it is convenient. Unlike a
conventional battery pack, it does not have to be fully discharged first. However,
as the battery pack will naturally discharge itself over time, it is best to charge it
the same day you plan to use it, or the day before.
Taking care of the battery pack
Always attach the terminal cover.
• Do not allow any metal objects to
touch the terminals, as this can cause
a short circuit and damage the battery
pack. Attach the terminal cover
whenever the battery pack is not
being used.
Keep the terminals clean.
• The camera, adapter or battery pack will not work properly if the terminals are
dirty. Check them before use, and wipe them with a dry cloth or tissue if
necessary.
Storing the battery pack
• If you do not use a battery pack for a period of more than a few months any
remaining charge may cause damage to the battery pack, and reduce usage time.
To prevent damage therefore, aim to use a battery pack's complete charge
before storage. See the BP-511 and BP-522 instructions for further details.
