Maintaining Batteries; Battery Life - Symbol Series 3300 System Administration Manual

Maintaining Batteries

Primary power for the Series 3300 is provided either by two 9-Volt alkaline batter-
ies in a carrier tray or by a rechargeable, nickel cadmium (NiCad) battery pack.
To prevent loss of data while replacing batteries, Series 3300 systems have two
lithium backup batteries. The backup batteries do not provide enough power to
operate the system.

Battery Life

The life of the primary battery pack is affected by many factors, including
temperature, the age of the batteries, and the data collection method. Battery life
is shortened by use in very high or very low temperatures, and by use of a
scanning device.
The approximate battery life between charges (NiCad) or replacement (Alkaline),
which reflects the data collection method, is summarized in Table 2-1. Note that
these values will vary with the application, and in particular, applications involving
modem and radio communications will shorten these times.
The lithium backup batteries provide sufficient power to preserve the contents of
memory for approximately approximately 300-400 hours.

Note
Alkaline batteries are NOT recommended for use with the PRC 3310 except in
case of emergency, due to the increased power consumption of the radio.
