To protect the battery from deep discharge (5 volts or less), the 
Trimble R8 system is designed to switch batteries or cease drawing 
power when the battery pack discharges to 5.9 volts. 

A battery that has reached the deep discharge level cannot be 
recharged and must be replaced. The following recommendations 
provide optimal performance and extend the life of your batteries:

•

Fully charge all new batteries prior to use.

•

Do not allow the batteries to discharge below 5 volts.

•

Keep all batteries on continuous charge when not in use. 
Batteries may be kept on charge indefinitely without damage to 
the receiver or batteries.

•

Do not store batteries in the receiver or external charger unless 
power is applied. 

•

If you must store the batteries, fully charge them before storing 
and then recharge them at least every three months.

Discharge the Lithium-ion battery before disposing of it. When 
disposing of the battery, be sure to do so in an environmentally 
sensitive manner. Adhere to any local and national regulations 
concerning battery disposal or recycling.

The Trimble R8 receiver does not supply power from either of its two 
ports.

A receiver’s firmware is the program inside the receiver that controls 
receiver operations and hardware. You can upgrade the firmware for 
the Trimble R8 receiver using the WinFlash utility provided on the 
Trimble R7, Trimble R8, 5700, and 5800 GPS Receivers CD.
