When To Replace Or Recharge Batteries - Symbol Series 3100 Product Reference Manual

When to Replace or Recharge Batteries

The Series 3100 and 3500 provide two types of indicators to notify you when battery
power is running low: warning messages and modified cursors. These indicators may
be changed or disabled by an application program.
• LOW POWER — When the battery is low, the cursor changes as shown inTable
6-4. If ERR3000 is loaded, the message LOW BATTERY also appears. At this level,
the terminal continues to operate, but there is probably less than 1 hour of usable
power left.
Note: When the LOW BATTERY message is displayed on PDT
3500 terminals, the 2D scanner will not scan until the
battery is recharged or replaced.
• VERY LOW — When the power is very low, the REPLACE BATTERY message
appears and the system powers off. Replace or recharge the battery before
attempting to use the terminal. If the battery is not immediately recharged or
replaced, data may be lost.
Battery life varies between 500 - 1000 charge / recharge cycles. This variation depends
on the depth of discharge. In general, replace batteries which exhibit less than 80% of
their total rated capacity.
