Battery Life
The ProMark2 receiver is conveniently powered by 2 standard AA batteries. Any battery type
in the AA form factor can be used in the ProMark2 receiver, including both disposables
(alkaline, lithium) and Rayovac® IC3 rechargeables. Other rechargeables are not
recommended. Lithiums will run the ProMark2 for the longest period of time, followed by
Rayovac® IC3, then alkaline. Rechargeable batteries other than the Rayovac® IC3 may not
have sufficient power to drive the antenna and may result in cycle slips in the collected data.
Figure 2.2 shows the ProMark2 battery life vs temperature for a set of 2 alkaline and a set of 2
lithium batteries. These graphs were produced from test results using the Energizer brand of
batteries.
