Tips for using the battery pack
Notes on the rechargeable battery pack
Caution
Never leave the battery pack in temperatures above 60°C (140°F), such as in a car parked in
the sun or under direct sunlight.
The battery pack heats up
During charging or recording, the battery pack heats up. This is caused by energy that has
been generated and a chemical change that has occurred inside the battery pack. This is not
cause for concern, and is normal.
Battery pack care
• Remove the battery pack from the camcorder after using it, and keep it in a cool place.
When the battery pack is installed to the camcorder, a small amount of current flows to
the camcorder even if the POWER switch is set to OFF. This shortens battery life.
• The battery pack is always discharging even when it is not in use after charging.
Therefore, you should charge the battery pack right before using the camcorder.
The life of the battery pack
If the battery indicator flashes rapidly just after turning on the camcorder with a fully
charged battery pack, the battery pack should be replaced with a new fully charged one.
Charging temperature
You should charge batteries at temperatures from 10°C to 30°C (from 50°F to 86°F). Lower
temperatures require a longer charging time.
