WARNING – Do not damage the rechargeable Lithium-ion battery. A 
damaged battery can cause an explosion or fire, and can result in 
personal injury and/or property damage. 
To prevent injury or damage: 
– Do not use or charge the battery if it appears to be damaged. Signs of 
damage include, but are not limited to, discoloration, warping, and leaking 
battery fluid.
– Do not expose the battery to fire, high temperature, or direct sunlight. 
– Do not immerse the battery in water. 
– Do not use or store the battery inside a vehicle during hot weather. 
– Do not drop or puncture the battery. 
– Do not open the battery or short-circuit its contacts.

The Trimble R8 receiver can be powered by its internal battery or by 
an external power source connected to Port 1. Typically, one internal 
2.0 ampere-hour battery provides approximately 5.5 hours of 
operation during an RTK survey using the internal radio in rover mode 
and approximately 3.5 hours of operation as an RTK base (this varies 
according to temperature and wireless data rate).

If an external power source is connected to Port 1 it is used in 
preference to the internal battery. When there is no external power 
source connected, or if the external power supply fails, the internal 
battery is used. 

WARNING – Avoid contact with the rechargeable Lithium-ion battery if it 
appears to be leaking. Battery fluid is corrosive, and contact with it can 
result in personal injury and/or property damage.
To prevent injury or damage:
– If the battery leaks, avoid contact with the battery fluid. 
– If battery fluid gets into your eyes, immediately rinse your eyes with 
clean water and seek medical attention. Do not rub your eyes! 
– If battery fluid gets onto your skin or clothing, immediately use clean 
water to wash off the battery fluid.
