Battery
The receiver is equipped with two nonremovable, on-board,
rechargeable Lithium-Ion battery packs connected to the
receiver’s power board. Each one of these Lithium-Ion
battery packs is 7.4 V and 3 Ah, giving you a total power of
7.4 V, nominal, and 6 Ah when fully charged.
With a full charge, the internal batteries should power both
the GPS+ receiver and the radio modem for at least 16
working hours for the HiPer GD or 12 hours for the HiPer
GGD. If the internal radio modem is turned off, and with
fully charged on-board batteries, the GPS+ receiver should
run at least 18 hours for the HiPer GD or 14 hours for the
HiPer GGD.
The Li-Ion batteries used in the receiver should run at no
less than 98% capacity after 500 charging cycles. These
batteries do not need to be drained before recharging.
A battery charger (AC adapter) is included with the
standard package. See Appendix B for technical
specifications on the battery.
