Cautions for the Lithium Battery use

Do NOT charge the Battery.

If you reverse the current flow with an external power supply (connect the higher voltage power supply with the reverse direction of the discharge flow or connect 3 batteries with one reverse connected battery, etc), the battery starts to be charged and the electrolyte is dissolved, then the heat generation or inner pressure rising could be caused by a gas generation, or the danger of leakage, breakage, firing could be happened by an inner short circuit generation.

Do NOT execute the compulsory discharge of the battery.

If you execute the compulsory discharge until the battery shows the voltage reversion (the condition that the voltage shows below 0V), the electrolyte would be dissolved and the gas could be generated, then the leakage, breakage, firing could be happened by a heat generation or the inner pressure rising.

Do NOT mix-Batteries.

If you connect the used and new batteries together or mix different type of batteries, difference of discharge performance could cause the electrolyte dissolving by old battery’s over-discharge, and could be a reason of leakage, breakage, firing by a heat generation and inner pressure rising.

Do NOT heat battery or throw it into the fire.

If the battery temperature would rise over 100℃, electrolyte could be boiled or the resin part could be melted, then the leakage, breakage or firing could be happened. And, if the battery would be put into the fire, electrolyte’s organic solvent or Lithium metal firing could cause a dangerous situation.

Do NOT make the short-circuit condition (to the metal part, etc) with the positive and negative pole of the battery.

If the battery +terminal and –terminal are connected with the cable or other metal parts directly, the metal part could be heated and fired. And, the over current flow could cause the heat generation, and like a battery heating condition, the electrolyte could be boiled or the resin part could be melted then there could be a risk of leakage, breakage or firing.

Do NOT solder the battery directly.

If you solder the battery directly, the heat could cause the Lithium melting then the battery inner part would be a short-circuit condition, and there is a possibility of electrolyte boiling, resin part melting which could cause a risk of leakage, breakage or firing.

Do NOT make a reverse-connection of the positive and negative pole.

If the battery’s positive and negative terminal would be a reverse-connection condition, the battery could consists the short circuit depends on the machine, and the electrolyte could be boiled or the resin part could be melted and there is a risk of leakage, breakage or firing.

Do NOT dissolve the Battery.

If you dissolve the battery, the battery could consists the short circuit or battery’s inner Lithium metal is opened and the moisture in the air could cause the reaction. And, there could be a risk of heat generation, firing or the breakage by a leaked electrolyte.

Do NOT modify or reconstruct the Battery.

If you make a mold work with the resin or other materials, the safety vent could be blocked, and if the inner pressure would be rose then there is a risk of breakage because the safety vent will not work. So, do not modify or reconstruct the battery for an efficient and safe use of the battery.

Please see the below cautions for keeping batteries.

If you keep batteries without packages, please pay attention not to contact and short each other.

Keep batteries in the ventilated, dry and moderate temperature condition (before or after use for the intended purpose). The high temperature or humidity could cause the heat deterioration or leakage of the battery.
