When to Replace or Recharge Batteries

The Series 3100 provides 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 in
6-2. 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.
• 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.
