Common
Battery care / information
Introduction
Your Entel radio is supplied with a high performance
Lithium-Ion (Li-Ion), or primary type Lithium battery.
These batteries:
•Extend talk time
•Reduce the battery’s size and weight
•Do not suffer from ‘memory effect’ that reduces the
life of Ni-Cad and NiMH batteries
•Have a low toxicity, therefore reducing the impact
on the environment
Battery Pack Precautions
•Switch the transceiver OFF before charging
•Charge the battery pack before use
•Do not recharge the battery pack if it is already fully
charged
•Charge the battery in accordance with the
instructions enclosed with your charger
•Do not charge the transceiver and/or battery pack
if they are wet
The battery pack includes potentially
hazardous components. Please:
•Do not disassemble or reconstruct battery
•Do not short-circuit the battery
•Do not incinerate or apply heat to the battery
•Do not immerse the battery in water unless
attached securly to the radio or get it wet by other
means
•Use only the specified charger and observe charging
requirements
•Do not pierce the battery with any object or strike
it with an instrument
•Do not use the battery pack if it is damaged in any
way
•Do not reverse-charge or reverse-connect the
battery
•Do not touch a ruptured or leaking battery
If liquids from the battery get into your eyes,
immediately:
•Wash your eyes out with fresh water and
avoid rubbing them
•Seek medical treatment
Battery Pack
•If a battery is not to be used for an extended
period of time (e.g. several months) remove the
battery pack from the equipment and store in a
cool and dry location (around 0°C) part charged.
Do not fully discharge the battery before storage
•Each charge cycle reduces the battery’s life.
Minimise the number of times you charge your
battery especially in hotter environments which
further shortens a battery’s life.
GMDSS Battery (CLB750x)
The GMDSS batteries (CLB750L \ G \ M depending
on which cells have been used in the battery pack)
are non-rechargeable Lithium batteries. The battery
is supplied with a security seal that must be removed
before fitting to the radio. An expiry date is printed
on the battery. Do not use this battery if past the
expiry date. Replacement batteries are available from
your local authorised dealer. If you require assistance
where to purchase please contact Entel for details.
Under no circumstances must you
attempt to recharge these batteries
Note: only genuine Entel batteries should be used.
Customer satisfaction is assured as you can not be
supplied with sub standard, potentially dangerous
battery packs from 3rd party manufacturers, ensuring
it delivers the expected capacity and endurance.
On HT series batteries a breathable membrane is
used.This is clearly marked on the battery label.
Piercing the membrane will allow water ingress to
the battery, and will invalidate the warranty.
