Operation
The batteries take approximately eight hours to charge fully. The
batteries are charged in parallel, so one battery takes as long to charge
as two batteries.
The internal batteries start charging whenever an external power
supply of greater than 15 V is detected.
When using two 5700 receivers as the reference and roving receivers,
you can use an external battery to power the reference receiver, and
use its two internal batteries in the rover. To charge both sets of
batteries, connect both receivers to power supplies as shown in
Figure 3.3. If there is no reference receiver that you can use, extra
batteries for the rover must be charged using the Lithium ion battery
charger (Part Number 41114-10).
