Frequently Asked Questions
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.
What will happen if batteries with different capacity are packed together?
If batteries with different capacity or new and old batteries are used together, leakage, zero voltage and so on might happen. During charging, some batteries may be overcharged while others remain undercharged. During discharge, some batteries cannot discharge fully while others might over discharge, potentially damaging the battery.
What are the possible reasons for zero voltage or low voltage of the battery pack?
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.
What are the possible reasons if the rechargeable battery or battery pack cannot be charged?
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 abnormality 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.
