Battery
The logger uses a pack of three rechargeable 1.2 V nickel-metal-hydride
(NiMH) cells. Only battery packs supplied by Datapaq are suitable.
Service life of the rechargeable NiMH battery is about three years or 1,000
charge/discharge cycles. The logger must be returned to Datapaq for battery
replacement.
For subsidiary power, the logger also contains a lithium AA battery. This will
normally last for the life of the logger, but, if replacement is needed, the logger
must be returned to Datapaq.

Battery Life

Battery life (discharge time) of NiMH rechargeable batteries is affected by the
following factors.
