XL-B2 Lithium Ion Battery Pack for 7-Series
Recorders
The rechargeable lithium ion XL-B2 is a replacement
battery pack for Sound Devices 7-Series Audio Recorders. The 7.2 V,
4600 mAh battery pack can be used as the primary power source for
the recorder or as an onboard backup supply. It is charged by the
recorder’s charging circuitry when external DC is connected
to the recorder.
The battery pack may or may not have charge upon receipt. You must
charge the battery pack fully before operation.
Charging and Operating
Times
• Refer to your product instructions for information on
charging
and operating times.
• You will get longer runtime if you turn the product off
when it is not in operation.
• Charging and operating times will vary– it is good
practice to have two or three times as many battery packs as you
think you will need.
• Operating time will be shorter in low temperatures than at
room temperature. You can use the battery pack between 0° and
40° C (32° to 104° F), but it works best between
10° and 30° C (50° to 86° F).
• If the battery pack starts to provide less operating time
than usual (at normal temperatures) it has reached the end of its
life and should be replaced.
