Alkaline disposable batteries
EPS2 comes with 3 pcs AA super alkaline batteries, also known as penlight or LR6. Alkaline batteries are
cost effective and give a long battery life time in temperatures from 0-60°C. Alkaline batteries are not
commended at temperatures below 0°C.
The included batteries are special high grade quality and ensure longest operation of your EPS2.
A rule of thumb for alkaline batteries (@ 20°c):
- If your EPS2 Microtracker wakes up twice a day to transmit its position you can expect battery life
time of 2 years or more.
- If your EPS2 Microtracker only wakes up once a day to transmit its position the expected battery
life time is approximately 5 years!
- If your EPS2 wakes up 20 times a day but only needs to send its position once a day you can expect
1 year battery life time.
It is important only to use fresh and equal alkaline batteries. Failing to do so can significantly reduce the
operating time or worse – it batteries might leak and destroy the electronics. If you are in doubt, please
contact us so we can send you fresh super alkaline batteries.
Ni-MH re-chargeable batteries
Ni-MH (Nickel-Metal Hydride) batteries are the preferred batteries if you plan to use your EPS2 below 0°C
and down to -20°C. Ni-MH batteries are re-chargeable and can thus be used for many times but suffer self-
discharge that shortens the operating time somewhat compared to alkaline batteries. Having this in mind
you should only use Ni-MH batteries when needed due to low temperatures.
If you need to run your EPS2 on Ni-MH batteries you need to configure it for this type of batteries using the
’BATTYPE’ command. Please see page 13.
Battery replacement
After inserting new batteries you should press the RESET-button. After this the red LED should flash fast for
a few minutes – it is then ready and can receive SMS if required.
Pressing RESET-button does not affect your configuration.
