FAQ:
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.
Q: What are the possible reasons if the rechargeable battery or rechargeable battery pack cannot be charged?
A: The battery is zero voltage or there is battery with zero voltage in the battery pack.
There is wrong connection inside the battery pack.
There is abnormally of electronic components and/or PCB inside the battery pack.
There is failure in charger.
Outer element causes the charging efficiency to be too low, such as extremely low or high temperature.
