Using batteries safely is crucial to prevent accidents and ensure optimal performance.
Please follow these guidelines to ensure the safe handling, charging, and storage of batteries:
1. Inspect Battery Wrappers
Do not use batteries with torn or damaged wrappers, including small nicks or tears.
Damaged wrappers can lead to short circuits and pose a safety risk.
Replace batteries with damaged wrappers immediately.
2. Use Protective Cases
Always store loose batteries in protective cases or battery sleeves.
Avoid keeping batteries loose in pockets, purses, or bags where they can come into contact with metallic objects like keys or coins.
Metal objects can cause a short circuit and potentially lead to injury.
3. Avoid Extreme Temperatures
Do not expose batteries to extreme temperatures (above 100°C or 212°F), including excessive heat or cold.
High temperatures can cause batteries to vent, while cold temperatures can affect their performance.
Store batteries in a cool, dry place within the recommended temperature range.
4. Prevent Complete Discharge
Avoid fully discharging batteries below the recommended voltage levels.
Never allow a battery’s voltage to drop below 2.5V under load or 3V when unloaded.
Discharging batteries too low can damage them and reduce their lifespan.
5. Proper Charging
Charge batteries fully (to 4.2V) before their first use.
Use high-quality battery chargers specifically designed for the battery type you are using.
Avoid overcharging batteries (above 4.3V) as it can lead to overheating and potential hazards.
6. Correct Installation
Never use force to install a battery.
Ensure that batteries are inserted in devices with the correct polarity, aligning the positive (+) and negative (-) contacts properly.
Incorrect installation can cause damage or malfunctions.
7. Respect Current Limits
Be aware of the current limits specified in the battery’s specifications.
Never exceed these limits to prevent overloading the battery, which can result in overheating, venting, or other safety issues.
8. Unattended Charging
Never leave batteries unattended while charging.
Stay nearby and monitor the charging process to promptly address any issues that may arise.
9. Proper Storage
Do not store your li-ion batteries fully charged for an extended period of time (weeks or more).
If you need to store batteries for an extended period, keep them in a cool and dry place.
It is recommended to store Li-ion batteries at approximately 3.6V – 3.7V in individual boxes or cases specifically designed for battery storage.
10. Use Compatible Chargers
Only use battery chargers that are designed specifically for the type of battery you are using, especially when charging Li-ion batteries.
Using inappropriate chargers can lead to overcharging, overheating, or other safety risks.
Always refer to the manufacturer’s instructions and safety recommendations specific to the batteries you are using. Proper battery handling is essential to prevent accidents and ensure your safety.
