Battery
For your safety, inspect the battery regularly for any signs of damage, such as cracks or surface
damage caused by an impact or the battery being dropped. Fit a new battery if there are any signs of
damage.
Warning! Risk to personal safety. Sepura TETRA radios have been tested and
certified using Sepura approved batteries. The use of non-approved batteries may
damage the product, will result in non-compliance with regulatory requirements,
compromise the product safety ratings including SARS, reduce the length of operating
time and will invalidate the product warranty.
Checking the battery charge
Always check the amount of battery charge before lengthy periods of operation. A fully charged
battery should provide continuous operation for a full shift, depending on a number of operational
factors such as how the radio is operated, the operating environment (temperature and network
signal strength) and the condition of the battery. When the radio is powered on, the amount of charge
remaining may be displayed as a percentage (%) on the screen.
Battery charge indicators
A battery meter appears on the status line at the top of the radio display. The meter consists of 4 bars
comprising 8 segments that fill and empty corresponding to the estimated amount of charge
remaining.

Optimising battery life
A fully charged battery should last a full shift (approximately 12 hours) but this depends on a number
of operational factors, such as how the radio is operated, the operating environment (temperature
and network signal strength) and the condition of the battery.
