Sound Devices XL-B2 Lithium Ion Battery 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.

Features:

• 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.
