Battery Care
Base station kit shipments to North America include a 33 AHr
deep-discharge gel lead acid battery. This battery provides all
day operation with ample power for both the PDL and the GPS
RTK reference station.
International Shipments
For shipments outside of North America, we include battery bag,
power cables with fuse, and hardware for a user supplied
battery. Select a deep discharge battery of the type designed for
golf cart or wheel chair operation, and that has a capacity of 33
AHr or greater. Batteries designed for automotive use will be
damaged by the repetitive discharge/charge cycles and should
be avoided.
Charging
The supplied charger provides two-stage charging and should be
connected to the battery following every full day of operation to
assure good battery life and performance. The first stage quickly
charges the battery to capacity and the second stage trickle
charges the battery to maintain a full charge.
If the battery is maintained in storage for an extended length of
time, it is important to periodically charge the battery as
extended time in a discharged state may damage the battery.
