Battery Life Of The netpad Variants
Route Accounting:
Using a netpad with a GSM radio, the user performs one transaction per minute,
where each transaction includes a scan, a transmission to the host, and an update
from the host. The terminal is used for 30 minutes, followed by 15 minutes in
Stand-By mode.
9.1.6.2 Charging Times
The standard netpad battery charging solutions do not use trickle charging or fast
charging. The netpad battery pack is charged at a constant rate. The actual charge
time experienced is dependant on capacity of the battery pack and the ambient tem-
perature. The approximate charging times for fully discharged netpad battery packs
are given in Table 9.2.
Important: As a safety precaution, charging the netpad battery should be
limited to the temperature range: 0°C to +45°C (32°F to 113°F).
Outside of these limits, the safety circuits of the netpad battery
pack will not allow the battery to charge. Discharging should be
limited to the temperature range: -20°C to +60°C (-4°F to 140°F),
and -20°C to +55°C (-4°F to 131°F) for scanner variants.
