MAINTENANCE RULES
FOR LI-ION AND LI-PO BATTERIES:
- The first charging process is very important!
Please charge the battery completely before the first use.
- If a battery is discharged below its nominal voltage, this might
trigger further processes, which could damage or destroy the
battery.
- Therefore, ALPENHEAT batteries have built-in electronics that
switch off the device before such a deep discharge happens.
- Frequent overcharging can permanently damage the battery.
That's why the charger stops the charging process automatically
as soon as the battery is fully charged. Repeatedly reconnecting
a charged battery to the power supply will not increase the
charging level!
- Charging should normally only be carried out at room
temperature (about 18°C - 21°C). Avoid charging a cold
battery, as this might damage the cells. Allow the battery
to warm up at room temperature in order to charge it under
ideal conditions.
- High temperatures might also damage the battery. Never
leave the battery in the sun or in the car on hot and sunny days.
- Li-Ion batteries and Li-Polymer batteries should ideally be
stored at room temperature.
- Fully charged or empty Li-ion batteries should not be stored
for a longer period of time. In complex tests, the optimum
storage condition was determined at a capacity of 30 %
to 50 % and at a low temperature, but not below 0 °C.
- Storage at -5 °C to 45 °C (Li-Ion) and at 0 °C to 40 °C
(Li-Polymer)
is possible, but not recommended
- Batteries have to be charged every 6 months.
- Even if not in use batteries lose energy.
A Li-Ion battery loses about 3 % to 5 % per month.
- Always dispose of used and old batteries in an
environmentally correct way.
