Battery Use Guidelines
Always follow the warning information on the battery label and in
the user manual provided with the charging device.
NEVER use or attempt to charge a battery that shows signs of
damage or swelling, or has been dropped or received a ‘heavy
blow’. Damage to the battery may not always be obvious.
Take care when handling and charging batteries. Do not short-
circuit batteries. Avoid deep discharge of batteries.
Do not open or disassemble batteries.
Do not incinerate batteries or expose to temperatures above 85°C
(185°F).
Do not immerse batteries into water or expose the battery contacts
to moisture.
Do not swallow batteries.
Sepura recommends that charging is only performed at an ambient
temperature b5 °C and +35 °C (41 °F and 95 °F).
Charging will be suspended when the internal battery cell
temperature is below +5 °C (41 °F) or above +45 °C (113 °F)
Rechargeable batteries have a limited number of charge cycles
and may eventually need to be replaced. We recommend replacing
batteries every two years or after 500 charge cycles.
Use original packaging for storage and transportation of batteries.
To achieve best battery performance, store batteries in a cool
dry place below +20°C/68°F. The temperature limits for storing
batteries over periods of time are listed below:
<1 month ..............................–20 °C to +45 °C (-4 °F to +113 °F)
<3 months: ...........................–20 °C to +35 °C (-4 °F to +95 °F)
3-12 months: ........................–20 °C to +25 °C (-4 °F to +77 °F)

charger is powered on.
The battery pocket is
for charging a single
battery.
The LED on the radio indicates the
battery charge status. Refer to the
radio user documentation for further
details.
Operation
Place the charger onto a flat surface, such as a table or
workbench. Connect the power supply to the DC socket at the rear
of the charger. Connect the wall block to a suitable mains outlet
(see Technical Data). The Green power LED will illuminate to
indicate that the charger is powered on.
To use, ensure that the radio with battery attached or battery
(separate) is fully inserted and seated correctly in the charger
pockets as shown below.
*A Charger Insert (part no. 300-01910) is required when charging an SC21 hand-held
radio with battery attached.
Typical charging time is approximately 2 hours although this will
vary dependent on the state of the battery and environmental
conditions.
Do not store batteries fully charged. After six months storage,
charge batteries for 36 minutes. Thereafter, recharge for 36
minutes every six months. Failure to store batteries correctly could
lead to reduced capacity and reduced battery life, and in extreme
circumstances damage to or complete failure of the battery.
