Battery Charging
The mobile computer’s cradles, snap-ons and spare battery chargers can be used to charge the mobile
computer’s main battery.
Before using the mobile computer for the first time, fully charge the main battery (until the charge
indicator light remains lit) see Table 1-1 on page 1-11. Charge time is less than four hours. The mobile
computer can be charged using a cradle, a CAM or MSR (with a charging cable) or the main battery
can be removed and charged using a spare battery charger.
The mobile computer is equipped with a memory backup battery which automatically charges from
the fully-charged main battery. When the mobile computer is used for the first time, the backup
battery requires approximately 15 hours to fully charge. This is also true any time the backup battery
is discharged which occurs when the main battery is removed for several hours. The backup battery
retains data in memory for at least 30 minutes after the mobile computer's main battery is removed.
When the mobile computer reaches very low battery state, the combination of main battery and
backup battery will retain data in memory for at least 72 hours.
Do not remove the main battery within the first 15 hours of use. If the main battery is
removed before the backup battery is fully charged, data may be lost.
Batteries must be charged within the 32° to 104° F (0° to +40° C) ambient temperature
range.
The following accessories can be used to charge batteries.
• Cradles: The mobile computer slips into the cradles for charging the battery in the mobile
computer (and spare batteries, where applicable). For detailed cradle setup and charging
procedures see:
• Single Slot Serial/USB Cradle on page 8.
• Four Slot Ethernet Cradle on page 12 and Four Slot Charge Only Cradles on page 14.
• Accessories: The mobile computer’s snap-on accessories provide charging capability, when
used with one of the accessory charging cables. For detailed snap-on setup and charging
procedures see:
•CAM on page 24
•MSR on page 18.
