FAQ for lithium rechargeable battery:
Q: Can I use Lithium batteries mixing with other battery types?
A: 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.
Q: What will happen if the batteries with different capacity are
packed together?
A: If the batteries with different capacity or new and old
batteries are used together, leakage, zero voltage and so on might
happen. If the batteries are rechargeable and are being charged,
some batteries are overcharged and other batteries is not in full
charged state. During the discharge, some batteries cannot
discharge fully and other batteries might over discharge. This way,
the battery will be damaged.
Q: What are the possible reasons for zero voltage or low voltage of
the battery pack?
A: Short circuit or open circuit of the connector or wrong
connection, de-soldering or cold solder joint between the batteries
and lead, wrong connection between the batteries.
