Main Battery Installation (MC3090G)
Battery Charging
Use the mobile computer cradles, cables and spare battery chargers to charge the mobile computer main battery.
The main battery can be charged before insertion into the mobile computer or after it is installed. There are two
main batteries for the MC3000, the Standard Battery and the Extended Life Battery. Either battery can be used, but
the Extended Life Battery requires a different Strap/Door Assembly. Use one of the spare battery chargers to
charge the main battery (out of the mobile computer) or one of the cradles to charge the main battery while it is
installed in the mobile computer.
Before using the mobile computer for the first time, fully charge the main battery until the amber Charge LED
Indicator remains lit (see Table 1-2 on page 1-8 fo r charge status indications). The S t andard Battery fully charges in
less than four hours and the Extended Life Battery fully charges in less than six hours.
The mobile computer is equipped with a memory backup battery which automatically charges from the main
battery whether or not the mobile computer is operating or is in suspend mode. The memory backup battery retains
data in memory for at least 30 minutes when the mobile computer’s main battery is removed or fully discharged.
When the mobile computer is used for the first time or after the memory backup battery has fully discharged, the
memory backup battery requires approximately 15 hours to fully charge. Do not remove the main battery from the
mobile computer for 15 hours to ensure that the memory backup battery fully charges. If the main battery is
