Lithium batteries provide a high energy density which is
often combined with a high rate capability to the benefit
of the customer. Due to these excellent performance
properties, Lithium batteries contain a certain safety
risk. If short-circuited, heat and sometimes sparks may
be generated. Mistreatment beyond the recommended
limits can cause gas generation, leakage and fire.
This guideline „Handling Precautions, Prohibitions
and General Supply Notices for VARTA Microbattery
GmbH CoinPower Batteries“ shall be applied to VARTA
CoinPower batteries. It shall be brought to the attention
of all persons who handle the batteries.
The customer is requested to contact VARTA
Microbattery GmbH in advance, if and when the
customer needs other applications or operating
conditions than those described in this document.
In this case additional tests and experiments may
be necessary to verify performance and safety under
such conditions. VARTA Microbattery GmbH shall not
be responsible for safety, performance, functionality,
compatibility or fitness for a particular purpose unless
such features have been expressly communicated and
described in the specification.
VARTA Microbattery GmbH will take no responsibility
for any accident when the cell is used under other
conditions than those described in this guideline.
VARTA Microbattery GmbH will inform, the customer
in writing of improvement(s) regarding proper use and
handling of the cell, if deemed necessary.
Do not modify and or open cells or batteries without
prior written approval by VARTA Microbattery GmbH.

Charging Current
Charging current should not exceed maximum charge
current specified in the Data Sheet.
Charging with higher current than recommended may
cause damage to cell performance and safety features,
and can lead to heat generation or leakage.
Charging Voltage
Charging at above 4.3 V, which is the absolute maximum
voltage, is strictly prohibited. The charging has to be
done according to the data sheet. The charger shall
be designed in accordance with this condition. Use
specified charger only.
Charging with higher voltage than specified may cause
damage to cell performance and safety features, and
can lead to fire, heat generation or cell leakage.
Charging Temperature
The cell shall be charged within the range of specified
temperatures in the Data Sheet. If the cell is charged at
a temperature out of the specified range, leakage, heat
generation, or other damages may occur.
Repeated charging and discharging at high and low
temperature may cause degradation of cell performance
even within the specified temperature range.
Prohibition of Reverse Charging
Reverse charging is prohibited. The cell shall be
connected correctly. The polarity has to be confirmed
before connecting any wires. Reverse charging will
cause damage to the cell(s) and will lead to a loss
of cell performance and cell safety (including heat
generation or leakage).
