Section 7 - Handling and Storage
1) Handling
● Never swallow.
If a battery is accidentally swallowed, see Section 4 - First Aid Measures.
● Never charge.
The battery is not designed to be charged by any electrical source. Charging can generate gas
and internal short-circuiting, leading to distortion, leakage, overheating, explosion or fire.
● Never heat.
Heating the battery to more than 100 deg. C can increase the internal pressure, causing
distortion, leakage, overheating, explosion or fire.
● Never expose to naked flames.
Exposing to naked flames can cause the lithium metal to melt, causing the battery to catch fire
and explode.
● Never disassemble or deform.
Disassembly or deforming the battery can cause leakage, overheating, explosion or fire due to
internal short-circuits.
● Never reverse the positive and negative terminals when inserting in electrical
equipment.
Inserting the battery incorrectly can lead to short-circuiting, charging or forced-discharging.
This can cause distortion, leakage, overheating, explosion or fire.
● Never short-circuit the battery.
Do not allow the positive and negative terminals to short-circuit. Never carry or store the
battery with metal objects such as necklaces or hairpins. Do not take multiple batteries out of
the package and stack or mix them when storing. Otherwise, this can lead to distortion,
leakage, overheating, explosion or fire.
● Never weld the terminals or weld wire to the body of the battery.
The heat of welding or soldering can cause the lithium to melt or cause damage to the
insulating material in the battery. This can cause distortion, leakage, overheating, explosion or
fire.
● Never use different batteries together.
Using different batteries together, i.e. different types or old/used and new or those of different
manufacturers, can cause distortion, leakage, overheating, explosion or fire because of the
differences in battery properties. Please consult Maxell before designing devices that use two
or more batteries connected in a series or parallel, even with the same battery type.
● Never touch liquid leaking from a battery.
If the liquid enters the eyes or mouth, see Section 4 - First Aid Measures.
