Can I force-discharge lithium batteries?
When batteries are force-discharged with an external power source, the voltage drops to under 0 volts (which is called
voltage reversal ) and internal gas is generated. This can lead to swelling, heat generation, leakage, rupture or fire.

Can I use Lithium batteries mixing with other battery types?
If different types of batteries are used together, or new batteries are used with old ones, the difference in characteristics
of voltage, capacity, etc., may cause over-discharge of the battery which is exhausted first, leading to swelling, bursting or fire.

Where should lithium batteries be stored?
Lithium batteries should be stored in a cool, dry place that is not exposed to direct sunlight and has minimal temperature
variation. Storage in areas subject to high temperature or humidity may cause deterioration in battery quality and durability.
To avoid short circuiting batteries during storage, be sure that the positive and negative terminals do not come into contact
with each other.

What is a short circuit?
If the positive and negative terminals of a battery come into contact with each other or with a conductive metallic object,
this can cause a short circuit, which generates heat. If cells or batteries are stacked on top of each other or mixed, the
resulting short circuit can lead to heat generation, leakage, rupture, and possibly fire.
