Can a rechargeable battery be used in a CEL-350?
Yes, the battery pack in the CEL-350 dBadge consists of 2 half-size NiMH AAA cells. This set of batteries is hard wired into the instrument and is not user changeable. A new rechargeable battery pack should be used to replace the originals in the CEL-350 dBadge Micro Noise Dosimeter when it no longer holds the charge. This replacement procedure can be carried out during the normal recalibration process when the instrument is returned to Casella CEL service laboratory. The rechargeable battery pack in the CEL-350 dBadge is not normally intended to be a user serviceable item.
