Safety Warnings & Usage Guidelines

Charge current should be less than the maximum value specified (45mA). Charging with higher current may cause damage, heat generation, or leakage.
Batteries must be charged with voltage less than 4.20V per cell. Charging beyond 4.25V is strictly prohibited and dangerous.
Charge batteries at 0°C-45°C environment temperature. Below 10°C, use reduced current (≤0.5C). Below 0°C, charging is prohibited.
Avoid high temperature environments (direct sunlight, hot vehicles) to prevent overheating, fire, or performance degradation.
Do not use in locations with strong static electricity or magnetic fields to avoid damaging safety devices.
If electrolyte gets into eyes, rinse with clean water and seek immediate medical attention.
Discontinue use if battery emits strange odor, generates heat, becomes discolored, deformed, or appears abnormal.
Clean battery terminals with dry cloth before use to ensure proper connection.
Tape battery terminals when discarding to prevent fire or explosion risks.

Frequently Asked Questions

Q: Can I use Lithium batteries mixing with other battery types?

A: Mixing different battery types or new batteries with old ones may cause over-discharge, leading to swelling, bursting or fire due to differences in voltage and capacity characteristics.

Q: What will happen if batteries with different capacity are packed together?

A: Using batteries with different capacity or mixing new and old batteries may cause leakage, zero voltage, overcharging, or over-discharging, which can damage the batteries.

Q: What are the possible reasons for zero voltage or low voltage of the battery pack?

A: Possible causes include short circuit or open circuit of connectors, wrong connections, de-soldering, or cold solder joints between batteries and leads.

Q: What are the possible reasons if the rechargeable battery or battery pack cannot be charged?

A: This could be due to zero voltage batteries, wrong internal connections, component failures, charger issues, or extreme temperature conditions affecting charging efficiency.
