2.3.3 BATTERY PACK MODULE (OPTIONAL)
This module, which includes batteries and charging circuitry that comprise the optional battery pack,
can provide 16 to 20 hours of continuous operation. The pack has a battery-monitoring circuit, which
will allow the battery to be charged within 12 hours and will then switch to trickle charge to maintain
a fully charged condition without damaging the batteries.
