Chapter 6. Maintaining The 3100/3500 Terminal; Batteries; Battery Life - Symbol Series 3100 Product Reference Manual

Batteries

The Series 3100 terminal's primary power is provided by a 9-Volt alkaline battery, a
rechargeable nickel cadmium (NiCd), or nickel metal hydride (NiMH) battery pack.
The PDT 3500 is powered by a single battery pack, which may be NiCd or NiMH.

Battery Life

Many factors affect battery pack life, including temperature, battery age, and data
collection method. Uses and operating conditions which affect battery life are:
• scanning
• radio communications
• very high operating temperatures
The approximate battery life between charges (NiCd, NiMH) or replacement (alkaline)
is summarized in Tables 6-1, 6-2, and 6-3. Note that these values vary with the
application. Applications involving modem and radio communications shorten these
times.

* Power consumption is highly application-dependent. The figures above represent battery life
of typical applications. However, battery life with individual applications will vary.
Note: Alkaline batteries are NOT recommended for use with the PDT
3110 or 3140.
