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 overcharge while others remain undercharged. During discharge, some batteries cannot discharge fully while others may 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, wrong connection, de-soldering or cold solder joint between the batteries and leads, or incorrect connection between the batteries.
What are the possible reasons if the rechargeable battery or battery pack cannot be charged?
The battery is at zero voltage, there is wrong connection inside the battery pack, abnormality in electronic components or PCB, charger failure, or external factors such as extremely low or high temperature affecting charging efficiency.
