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
Abattery 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.
Icon Description
Battery is fully charged.
Battery is 50% charge capacity.
Battery has >12% charge remaining.
Battery charge less than 12% charge remaining.
User Guide 5

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.
Try the following to help you optimise battery life on a daily basis:
Ensure that batteries are fully charged at the start of a shift.
Decrease the amount of time the backlight stays lit between key presses
(see Adjusting the backlight on page 40).
Keep your speaker audio volume to a minimum (see Adjusting the volume
on page 37).
Reduce the length of time the radio is transmitting and keep DMOor
telephone type calls to a minimum because they cause higher current
consumption.
Shorten the GPS reporting intervals if enabled (see GPS reporting options on
page 124).
6SC20 series – 04/2016

Charging the battery
Your radio is powered by a rechargeable battery. The battery may be
recharged many times but it will eventually need replacing to ensure
continuous maximum performance from your radio.
First time battery charging
New batteries (Standard battery part no. 300-01174 and High Capacity battery
part no. 300-01175) are supplied in 'storage mode' which means they have a
minimum amount of charge for storage purposes. Before using a new battery
for the first time it must be fully charged to reactivate it. If the battery is used
before it is reactivated (fully charged) the radio may not power on, or may
indicate a low battery status icon or low level of charge.
Battery chargers
Only use Sepura approved battery chargers. Use of non-approved chargers
may not fully charge the battery or damage it. Always read the user
documentation supplied with the charger for additional safety instructions
and how to use it.
Charging methods
The radio may be powered on or off during charging.
Attach the Charger cable to the sDAC connector at the base of the radio or
place the radio with battery attached into a charging dock. If the battery is
charged attached to the radio, and the radio is powered on, an indication of
the remaining time to fully charge the battery is displayed (in hh:mm format).
During charging, the tri-coloured LED on the radio indicates the charging
progress and the charging icon appears on the status line, providing there is
sufficient charge in the battery to support this function.
Status LED Description
Flashing
Orange
Battery temperature is either too hot or cold to
commence charging.
Solid Orange Charging in progress.
Solid Green Charging complete.
Solid Red Battery has failed to charge and may be not be chargable.
Contact your service provider or Sepura.
User Guide 7

The battery may be charged separately from the radio using a battery-only
charger.
Charging a 'flat' battery
If the battery is completely 'flat' (without charge) during storage or after a
long period of non-activity, it may fail to recharge or stop charging after 20
minutes. If this happens, disconnect and then reconnect the charger (or
power off the charger, then power on) to reset the battery.
Avoid charging a flat battery attached to a radio. During charging, the radio
will attempt to power on when the battery charge reaches a certain capacity,
which will drain the battery of its charge.
Fitting the battery
Ensure that the Smart/microSD card compartment cover is securely latched
before fitting the battery.
If a belt clip is fitted to the radio, lift the belt clip before attempting to fit the
battery. Do not attempt to insert the battery into the battery compartment
sideways under the belt clip. This may result in damage to the radio and the
belt clip.
To attach the battery, insert the battery into the battery compartment as
shown. Press the battery downwards until it clicks into position.
Removing the battery
Always power off before removing the battery.
8SC20 series – 04/2016

Push the safety latch on the bottom of the battery. Lift the battery upwards
and remove.
Using Sepura approved batteries
Your radio checks the authenticity of the battery when it is powered on and
has a number of battery management features that only work when a genuine
Sepura battery is fitted:
the remaining battery charge appears as a percentage when your radio is
powered on [customisable];
battery meter icons, showing the remaining battery charge;
a low battery warning appears when charge is low; and
you can check battery information, such as its authenticity, remaining
charge and serial number [customisable] (see Getting information about your
battery on the next page).
If your radio detects a non-approved battery, the message "Unidentified battery
-powering down" appears. The message is cleared by pressing any key.
If your radio detects a non-approved battery, the message "Unidentified
battery" appears.
If your radio detects a non-approved battery, the message "Unidentified battery
-powering down" and your radio powers off.
Caution: Non-approved batteries may not have inbuilt safety protection
features, and could potentially damage your radio (invalidating your
warranty) and affect your radio's safety and IP compliance ratings.
User Guide 9

Getting information about your battery
You can see information about the battery attached to your radio, such as the
remaining battery charge, whether the battery is authenticated (a genuine
Sepura battery) and the battery serial number [customisable].
Select Menu >Options >Battery Information.
The display shows:
Charge—the current remaining charge given as a percentage
Authenticated/Unauthenticated—a Sepura/non-Sepura battery is fitted
<serial number>—the serial number of the battery
Note: If a non-Sepura battery is fitted, the Charge is reported as 0%, the
battery is marked as Unauthenticated and the serial number is not shown.
