Entel HT912T [5/20] Battery care information

Common

Battery care / information

• Do not charge the battery near fires or under

direct sunlight

• 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 avoiding

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.

The battery pack has an over-current protection

circuit fitted. When charging a completely discharged

battery i.e. first charge, ensure the battery is removed

from the radio and then re-attached (if fitted to radio

when charging). This will reset the protection circuitry

and ensure normal operation. This process will need

to be repeated if the battery is allowed to completely

discharge in the future. In normal use this is unlikely.

Battery Communications

Each battery used with your ra dio has a

microprocessor fitted, which logs the number of times

your battery has been charged.

On a radio with an LCD display, the number of times

the battery has been charged, together with the

remaining charge cycles available, will be shown during

switch on (if not de-activated by your dealer).

The warranty on all batteries is 12 months or 450

charge cycles, whichever is the sooner. After 420

cycles, at switch on the radio will emit a series of

short tones, and on LCD models a waste bin icon will

flash to alert you to the need to buy a new battery.

After 450 cycles, at switch on the radio will emit a

series of long beeps, and on LCD models the message

will change to BATTERY COUNT EXCEEDED

REPLACE BATTERY. The radio will continue to

operate but its operational time may be reduced,

eventually failing all together.

Note: only genuine Entel batteries should be used.

Only genuine batteries offer the battery charge count

feature informing you when the battery is reaching the

end of its useful life. Non ATEX batteries will not

work on ATEX radios ensuring customer safety.

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
