2.2.1 Charging and Storing the Batteries (cont.)
Store the batteries at temperatures from –4°F to 131°F (–20°C to 55°C) for
periods of less than one month, or from 32°F to 104°F (0°C to 40°C) for
longer periods. (If you are transporting them for two days or less, the
batteries can withstand temperatures from –40°F to 158°F (–40°C to 70°C).
2.2.2 Replacing the Batteries
CAUTION! Replace batteries only with the specified rechargeable
batteries. The battery charges when the unit is off. Do not
attempt to recharge non-rechargeable batteries.
If you need to replace the rechargeable batteries, use the recommended 3.0
Ahr NiMH batteries (part number 200-081). While the batteries can be
recharged up to 600 times, it is best to replace them when they no longer
provide acceptable performance. To replace the batteries, remove the rubber
boot, open the panel located on the back of the PT878 unit, disconnect the
batteries, and replace with new ones (see Figure 3 on page 11).
