Guidelines on Charging, Use and Handling of Lithium-Ion Batteries

Lithium-ion batteries manufactured by SAMSUNG SDI have a high energy density and can cause serious personal injury or property damage when abused or misused. SAMSUNG SDI hereby will not be held liable for any damages for any failure by a customer to abide by the “Guidelines on Charging, Use and Handling of Lithium-Ion Batteries.”

  • Guidelines must be followed when distributing and using lithium-ion batteries.
  • Lithium-ion batteries contain high energy density.
  • Misuse or abuse of lithium-ion batteries can cause fires or explosions, which can cause serious personal injury or property damage.
  • Lithium-ion batteries manufactured by SAMSUNG SDI are not to be sold to individual consumers, but to battery pack manufacturers or system integrators only.
  • For safety purposes, SAMSUNG SDI strongly advises against distribution, purchase, and use of battery cells by individual consumers.

Battery Charging Precautions

Stop charging immediately when.
  1. you see smoke or liquid leakage, or smell foul odor.
  2. you see swelling, deformation, or discoloration of a Li-ion battery, battery module, or battery pack.
  3. a Li-ion battery, battery module, or battery pack gets overheated.
In any of the above cases, move the battery product to non-conductive surface such as a concrete floor area, away from the house or any flammables. DO NOT recycle, reuse, or distribute such battery without permission and dispose of them immediately in strict accordance with local regulations, as prescribed in “Battery Disposal Precautions.”
1. To ensure correct and safe charging and use of battery, follow the guidelines provided by SAMSUNG SDI and battery pack manufacturer.

User manual on product, charger, product specification, manuals for installation and/or maintenance, safety check sheet, etc.

2. Make sure to use a special charger designed for lithium-ion batteries or battery packs.

Using a charger other than the one provided by end-product and/or battery pack manufacturers increases a risk of fires and explosions. Li-ion batteries or battery packs must have a built-in protection mechanism such as protection circuitry so as to prevent fires or explosions caused by short-circuiting, overcharging, or overheating.
Such protection mechanism serves as a preventive measure for fires or explosions caused by short-circuiting, overcharging, or overheating. A fire or explosion may occur if a charger (including, but not limited to, USB port, car cigar jack lighter, chargers for tablet PC or cellphones) other than the specific lithium-ion battery charger provided by end-product and pack manufacturers is used, since using a wrong charger can overcharge (overcurrent, overvoltage) the battery which is likely followed by overheating, increasing a chance of fires or explosions.

Charging
  • Lithium-ion batteries require a constant current, constant voltage (CC/CV) type of charging algorithm.
    Please contact us if you intend to use a different type of charging other than above specified.
  • The charging current and voltage must be lower than the maximum current and voltage specified by SAMSUNG SDI.
  • The charging must be done under the operating condition specified by SAMSUNG SDI.
Discharging
  • Lithium-ion batteries require a constant current type of discharging algorithm.
  • The discharge current and voltage must be lower than the maximum current and voltage specified by SAMSUNG SDI.
  • The discharging must be done under the operating condition specified by SAMSUNG SDI
3. End-users or consumers should not use individual, loose lithium-ion batteries.

Li-ion batteries built with protection device, such as lithium-ion battery packs or systems, are to be used exclusively, not in loose cells. Any unauthorized disassembly, modification, or re-assembly of SAMSUNG SDI’s product is strictly prohibited. SAMSUNG SDI shall not be liable for any damages whatsoever caused by such act.

4. Make sure to monitor the battery or battery pack status at all times.

Such monitoring can help prevent a fire or explosion caused by short-circuitry, overcharging, overheating, etc.

5. Charge the battery at room temperature.

Too high or low temperature, and high humidity may cause damage in batteries.
As for the specifics of optimum operating conditions, please refer to the product manual and O&M manual.

6. Do not place chargers, lithium-ion batteries or battery packs on the bed, under the pillow, or on the couch.
7. Do not leave lithium-ion batteries or battery packs plugged into the charger for a long period of time.

Do not overcharge lithium-ion batteries. Do not charge lithium-ion batteries for an extended period of time.
The charger can automatically stop charging after a certain period of time. For more information, please refer to the charger manual.
