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.
