Canon XF705 Instruction Manual page 20

Preparing the Power Supply
• We recommend charging the battery pack in temperatures between 10 ºC and 30 ºC (50 ºF and 86 ºF).
Outside the temperature range of 0 ºC to 40 ºC (32 ºF to 104 ºF), charging will not start.
• To prevent equipment breakdowns and excessive heating, do not connect the supplied battery charger or
compact power adapter to voltage converters for overseas travels or special power sources such as those on
20
aircraft and ships, DC-AC inverters, etc.
NOTES
• If there is a malfunction with the battery charger, compact power adapter or battery pack, the charge indicator
will go out and charging will stop.
• For handling precautions regarding the battery pack, refer to Battery Pack (A 214).
• For approximate charging times and recording times with a fully charged battery pack, refer to the Reference
Tables (A 224).
• Charged battery packs continue to discharge naturally. Therefore, charge them on the day of use, or the day
before, to ensure a full charge.
• We recommend that you prepare battery packs to last 2 to 3 times longer than you think you might need.
• Repeatedly charging and discharging the battery pack will eventually shorten its battery life. You can check the
battery life on the [Battery/Hour Meter] status screen (A 201). Fully charging the battery pack and then
discharging it completely will give you a more accurate reading.
