6. Lithium Ion Polymer Battery Handling Guideline
6.1 In case of contacting the materials from a damaged or ruptured cell or battery:
Eye contact: Washing immediately with plenty of water and soap or for at least 15 minutes.
Get medical attention.
Skin Contact: Washing immediately with water and soap. Inhalation of Vented Gas:
Remove to fresh air. Get medical attention. Ingestion: Get medical
attention immediately.
6.2 Keep away batteries from children.
6.3 The cells/ batteries are requested to be stored within a proper temperature range specified in
this specification.
6.4 Do not store batteries in a manner that allow s terminals to short circuit.
6.5 Do not place batteries near heating sources, nor exposed to direct sunlight for long periods.
Elevated temperatures can result in reduced battery service life.
6.6 Charging Battery
Use only approved chargers and procedures. Improperly charging a cell or battery may cause
the cell or battery to flame or damage.
Charge the battery using the “CC/CV” or constant current /constant voltage method.
Do not charge the battery with a current or voltage higher than the specified maximum value in this specification. The absolute maximum charging voltage is 4.25V per cell.
Prohibit reverse charging of the battery. The battery must be connected correctly.
6.7 Discharging Battery
Discharge battery at the max current specified in this specification. If you plan to discharge
battery at a higher current than the max current, please consult us.
Avoid discharge the battery below 2.75V for each cell.
Do not over-discharge the battery. Over-discharging can damage the performance of the
battery. It should be noted that the cell/battery would be at an over-discharged state by its
self-discharge characteristics in case the cell is not used for long time. In order to prevent
over-discharging, the cell/battery shall be charged periodically to maintain between 3.7V and
4.1V.
6.8 Operation Temperature
The battery shall be operated (stored, charged and discharged) in the temperature specified in
This specification.
6.9 Cell/Battery Protection Circuit Module (PCM)
The cell/battery must be equipped with a PCM that protects the cell/battery from
overcharging, over-discharging and over-current.
6.10 Battery Short Circuit
Do not short-circuit a battery. A short circuit can result in over-heating of the terminals and
provide an ignition source. More than a momentary short circuit will generally reduce the
cell or battery service life and can lead to ignition of surrounding materials or materials
within the cell or battery if the seal integrity is damaged. Extended short-circuiting creates
high temperature in the cell and at the terminals. Physical contact to high temperatures can
cause skin burns. In addition, extended short-circuit may cause the cell or battery to flame.
6.11 Prohibit reversing cell polarity within a battery assembly.
6.12 The cell edge of the heat seal zone is electrically conductive. Avoid the edge cross battery
terminals, PCB, or conductive surfaces.
6.13 Do not bend, fold or fall the battery or part of the battery. It may cause the battery be
damaged and result in the battery swelling, leaking, explosion or ignition
6.14 Do not open or manipulate the folded cell edge.
6.15 Do not bend or fold the sealing edge. And do not tear off the sealing film.
6.16 Battery Pack Design
The battery housing should have sufficient mechanical strength.
No sharp edge components shall be inside the battery housing. The sharp edge may destroy
the cell packaging.
No cell movement is allowed in the battery housing.
The ultrasonic head shall not directly/ or indirectly pressed the cell if you need to enclose
the battery housing by ultrasonic method. Please consult us for designing the ultrasonic
head. Avoid designing airtight battery housing.
6.17 Battery Assembly
We recommend ultrasonic welding or spot welding to connect battery with PCM or other
parts. If you employ manual solder method to connect tab with PCM, please pay attention to
the followings:
Use a solder with temperature controlled and ESD.
Soldering temperature should not exceed 300℃.
Soldering time should not be longer than 3s.
Soldering times should not exceed 5 times.
Keep battery tab cold down before next time soldering.
Do not directly heat cell body. It may cause the battery be damaged by heat above 90℃
6.18 Battery Disassembly
Never disassemble a battery.
Should a battery unintentionally be crushed, thus releasing its contents, rubber gloves must
be used to handle all battery components. Avoid inhalation of any vapors that may be
emitted.
6.19 Do not mixed Batteries and Types. Avoid to use old and new cells or cells of different sizes,
different chemistry or types in the same battery assembly.
6.20 Other Warnings
Do not heat or dispose the battery into fire, water or other liquids.
Do not put the battery into microwave, washing machine or drying machine.
Do not use a damaged battery.
