Note:Apex III Battery Packs use Nickel Metal Hydride (NiMH) composition, they DO
NOT succumb to memory (hysteresis) loss as do Nickel Cadmium (Ni-Cd)
batteries. Apex III Battery Packs can therefore be charged while in any state-of-
charge and DO NOT require full discharge prior to charging; however, it is still
recommended that the Battery Pack be fully discharged periodically to reset the
internal gas gauge circuitry.
5. If your Apex III Portable Data Collection Terminal (PDT) is ready for another Battery
Pack, simply remove the installed Battery Pack and replace it with a fully charged
Battery Pack from the External Charger (refer to the Apex III PDT/Battery Pack
Notes below).
Apex III PDT/Battery Pack Notes
1. DO NOT attempt to operate the Apex III PDT once it has powered down due to a low
battery condition. When the battery pack is exhausted, leave the exhausted Battery
Pack in the Apex III until you can either charge it in place by placing the Apex III in
the Apex III Dock, or swap the Battery Pack with a charged Battery Pack.
Information in volatile memory (RAM) will be preserved since the Apex III PDT is
configured so that even with an exhausted Battery Pack enough energy is retained to
maintain the information for an extended period of time. DO NOT leave the unit
WITHOUT a Battery Pack for more than 5 minutes.
2. It is recommended that the user place the Apex III PDT in “Suspend” and change to a
fully charged Battery Pack or recharge the installed Battery Pack after receiving the
“Change Battery” message. After charging the Battery Pack, pressing the “Suspend”
button again will restore the unit to the last operation performed. If unit operation is
continued and the “Battery Critical” alarm occurs the unit will shutdown and cannot
be restarted. The installed Battery Pack must be replaced with a fully charged Battery
Pack or the installed pack recharged in the Apex III Dock.
Battery Pack Life
Average Battery Pack life expectancy is 400 charge cycles, where a charge cycle
encompasses the period of use to full depletion then full charge. After the 400 cycle period,
the Battery Pack capacity remaining will be approximately 80%.
q Avoid interruptions in usage by always keeping a spare Battery Pack on hand.
q Alternate spare Battery Pack use so that all Battery Packs receive uniform use.
q Battery Packs can lose approximately 1.1% of their charge per day sitting on the shelf.
Therefore a fully charged Battery Pack not kept in the charging slot will require
recharging in less then 100 days.
