Put the battery pack in a pocket to warm it up, and install it on your camcorder right before you start taking shots.
Use a large capacity battery pack:
Frequent use of the LCD screen or a frequent playback, fast forward or reverse operation wears out the battery pack faster. We recommend using a large capacity battery pack:
Be sure to close the LCD screen when not recording or playing back on your camcorder. The battery pack is also consumed when your camcorder is in recording standby or playback pause.
Have spare battery packs ready for 2 or 3 times the expected recording time, and make trial recordings before making the actual recording.
Do not expose the battery pack to water. The battery pack is not water resistant.
About the remaining battery time indicator
When the power goes off even though the remaining battery time indicator indicates that the battery pack has enough power to operate, charge the battery pack fully again. Remaining battery time will be indicated correctly. Note, however, that the battery indication will not be restored if it is used in high temperatures for a long time, or if left in a fully charged state, or when the battery pack is frequently used. Use the remaining battery time indication as a rough guide only.
The mark that indicates low battery flashes even if there are still 20 minutes of battery time remaining, depending on the operating conditions or ambient temperature.
About storage of the battery pack
If the battery pack is not used for a long time, fully charge the battery pack and use it up on your camcorder once a year to maintain proper function. To store the battery pack, remove it from your camcorder and put it in a dry, cool place.
To discharge the battery pack on your camcorder completely, touch 
(HOME) 
(SETTINGS) [GENERAL SET] [A.SHUT OFF] [NEVER], and leave your camcorder in recording standby until the power goes off (p. 76).
About battery life
Battery capacity decreases over time and through repeated use. If decreased usage time between charges becomes significant, it is probably time to replace it with a new one.
Each battery’s life is governed by storage, operating and environmental conditions.
About handling of your camcorder
On use and care
Do not use or store the camcorder and accessories in the following locations:
Anywhere extremely hot, cold or humid. Never leave them exposed to temperatures above 60 C (140 °F), such as under direct sunlight, near heaters or in a car parked in the sun. They may malfunction or become deformed.
Near strong magnetic fields or mechanical vibration. The camcorder may malfunction.
Near strong radio waves or radiation. The camcorder may not be able to record properly.
Near AM receivers and video equipment. Noise may occur.
On a sandy beach or anywhere dusty. If sand or dust gets in your camcorder, it may malfunction. Sometimes this malfunction cannot be repaired.
Near windows or outdoors, where the LCD screen, or the lens may be exposed to direct sunlight. This damages the LCD screen.
Operate your camcorder on DC 6.8 V/7.2 V (battery pack) or DC 8.4 V (AC Adaptor).
For DC or AC operation, use the accessories recommended in these operating instructions.
Do not let your camcorder get wet, for example, from rain or sea water. If your camcorder
gets wet, it may malfunction. Sometimes this malfunction cannot be repaired.
If any solid object or liquid gets inside the casing, unplug your camcorder and have it checked by a Sony dealer before operating it any further.
Avoid rough handling, disassembling, modifying, physical shock, or impact such as hammering, dropping or stepping on the product. Be particularly careful of the lens.
Keep the LCD screen closed when you are not using your camcorder.
