Sony HDR-XR350, HDR-CX350V, HD-RCX300, HDR-CX370 manual 106

The “InfoLITHIUM” battery pack calculates the power consumption according to the operating conditions of your camcorder, and displays the remaining battery time in minutes.

The battery pack NP-FV50 is compatible with “ActiFORCE.”

“ActiFORCE” is a new generation power system. Battery capacity, boost charge, and the speed and accuracy of battery time remaining calculations have been improved when compared with current “InfoLITHIUM” P-series battery.

To charge the battery pack

Be sure to charge the battery pack before you start using your camcorder.

We recommend charging the battery pack in an ambient temperature of between 10 C to 30 C (50 °F to 86 °F) until the /CHG (flash/charge) lamp turns off. If you charge the battery pack outside of this temperature range, you may not be able to charge it efficiently.

To use the battery pack effectively

Battery pack performance decreases when the ambient temperature is 10 C (50 °F) or below, and the length of time you can use the battery pack becomes shorter. In that case, do one

of the following to use the battery pack for a longer time.

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: NP-FV70/ NP-FV100 (sold separately).

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: NP-FV70/NP-FV100 (sold separately).

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 (MENU)  [Show others]  [POWER SETTINGS] (under [GENERAL SET] category)  [A.SHUT OFF]  [NEVER], and leave your camcorder in recording standby until the power goes off (p. 83).

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.
