Toshiba laptop battery

A. Disassembly
Never disassemble a battery, as the electrolyte inside is strong alkaline and can damage skin and clothes.

B. Short-circuiting
Never attempt to short-circuit a battery. Doing so can damage the product and generate heat that can cause burns.

C. Throwing batteries into a fire or water
Disposing of a battery in fire can cause the battery to rupture. Also avoid placing batteries in water, as this causes batteries to cease to function.

D. Soldering
Never solder anything directly to a battery. This can destroy the safety features of the battery by damaging the safety vent inside the cap.

E. Inserting the batteries with their polarities reversed
Never insert a battery with the positive and negative poles reversed, as this can cause the battery to swell or rupture.

F. Overcharging at high currents and reverse charging
Never reverse charge or overcharge with high currents (i.e. higher than rated). Doing so causes rapid gas generation and increased gas pres-sure, thus causing batteries to swell or rupture.
Charging with an unspecified charger or specified charger that has been modified can cause batteries to swell or rupture. Be sure to indicate　this safety warning clearly in all operating instructions as a handling restriction for ensuring safety.

G. Installation in equipment (with an airtight battery compartment)
Always avoid designing airtight battery compartments.
In some cases, gases (oxygen, hydrogen) may be given off, and there is a danger of the batteries bursting or rupturing in the presence of a source of ignition (sparks generated by a motor switch, etc.).

H. Use of batteries for other purposes
Do not use a battery in an appliance or purpose for which it was not intended. Differences in specifications can damage the battery or appliance.

I. Short-circuiting of battery packs
Special caution is required to prevent short-circuits. Care must be taken during the design of the battery pack shape to ensure batteries cannot be inserted in reverse. Also, caution must be given to certain structures or product terminal shapes which can make short-circuiting more likely.

J. Using old and new batteries together
Avoid using old and new batteries together. Also avoid using these batteries with ordinary dry-cell batteries, Ni-MH batteries or with another manufacturer’s batteries. Differences in various characteristic values, etc., can cause damage to batteries or the product.
