Safety data sheet

Title Specifications of Lithium Ion battery (Cylindrical Type) page 5/12
･ Fix cells with mold case by rib, tape, glue etc., but do not make damage cells (especially
sealing part) by rib or sharp part of mold case.
In case of the battery pack is struck by hard shock or vibration, the battery pack has
possibility to cause leakage, smoke, explosion.
･ Weld mold case by glue. Do not weld mold case by ultra sonic welding.
② Protection Circuit
Have protection circuit function which is described below inside battery pack, to insure
safety of battery in case of misuse.
･ Overcharge Protection
At the voltage range 4.35 ±0.05V/cell (Recommend; 4.35 ± 0.02V/cell) by charge,
overcharge protection should work. Then charge current shall be shut down.
･ Over discharge Protection
At the voltage range 2.20~2.40V/cell, over discharge protection should work.
Then discharge current shall be shut down and consumption current is below
10µA(Recommend; 2µA).
･ Over discharge Current Protection
When discharge current exceed about 5.0A/cell, over discharge current protection should
work. Then over discharge current shall be shut down.
③ Electric circuit
･ To avoid to discharge during storage, design the low consumption current electronic
circuit(e.g. Protection circuit, fuel gauge, etc) inside battery pack.
④ Battery connection
･ Do not solder onto a battery in order to avoid a damage on the battery.
Weld spot welding lead plate onto battery, and solder lead wire or lead plate.
⑤ Precautions on label
･ Write maker’s name, trade mark, maker’s nation, model number and precautions on
label.
Precautions are based on chapter 14.
Write the precaution manual based on chapter 14.
9. Storage Condition
9-1 Storage Temperature and Humidity (less than 1 month)
･ Store the battery at temperature range -20~+35℃, low humidity (less than 70%RH) and
no corrosive gas atmosphere.
･ No condensation on the battery.
