Even when the device is switched off, a small current can flow that
leads to a deep discharge after a prolonged period of time. Deep
discharge damages the battery and, in extreme cases, will destroy
it.
A charge loss of 3% to 5% per month is possible for lithium-ion bat-
teries. The self-discharge is temperature-dependent and greater at
high temperatures.
The capacity of the battery is fully exhausted in the event of deep
discharge. In such cases, the voltage drops to as low as 0 volt.
In the battery, chemical reactions take place on the electrodes.
Such reactions can render them unusable. The battery loses con-
siderable capacity and can potentially no longer be charged. For
this reason, the battery must not be discharged below a type-
dependent end-of-discharge voltage and must be recharged as
quickly as possible.
Do not fully discharge lithium-ion batteries and
lithium-ion polymer batteries.
Good lithium-ion batteries usually have extensive protection or
monitoring circuits in the battery pack that prevent deep dis-
charging/overcharging and explosion.
Temperature range for use: -10°C to +55°C
Temperature range for charging: +5°C to +45°C
The ideal temperature range for batteries is at room temperature.
A sensor in the battery ensures that no quick charging takes place
outside this range.
Lithium-ion batteries can be charged up to 1,000 times (capacity-
dependent). This value is only achieved under optimum conditions.
The number of cycles could decrease depending on battery treat-
ment and care. The capacity decreases over the course of the
service life.
Batteries should generally be replaced below 70% nominal
capacity.
Lithium-ion batteries and lithium-ion polymer batteries can and may
be recharged at any time. These batteries do not have any
memory effect. It is only necessary to avoid frequent brief charging.
Even full charging in several stages, with or without partial dis-
charge in between stages, does no harm.
Lithium-ion batteries and lithium-ion polymer batteries must not be
fully discharged.
