Batteries
The SPS985 GNSS smart antenna has one Lithium-ion battery which can be charged when it is
plugged into an external power source through Port 1, or the battery can be removed for charging.
During measurement operations, each internal battery typically provides about 4 hours of power if
using the internal Rx (receive) radio and about 3.5 hours operating as a base station using the
internal transmit radio. These times vary according to the type of measurement and the operating
conditions.
Battery safety
Charge and use the battery only in strict accordance with the instructions provided.
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.
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.
Connecting the receiver to a vehicle battery
WARNING – Use caution when connecting battery cable's clip leads to a vehicle battery. Do not allow any metal
object or jewelry to connect (short) the battery's positive (+) terminal to either the negative (-) terminal or the
metal of the vehicle connected to the battery. This could result in high current, arcing, and high temperatures,
exposing the user to possible injury.
WARNING – When connecting an external battery, such as a vehicle battery, to the receiver, be sure to use the
Trimble cable with proper over-current protection intended for this purpose, to avoid a safety hazard to the user
or damage to the product.
