If lithium-ion batteries are not used and managed safely, risks such as fire, explosion, and performance degradation may occur. Below are guidelines for the safe management of lithium-ion batteries:

1. Safety Management During Battery Charging

(1) Overcharge Prevention

Repeatedly fully charging (100%) the battery can shorten its lifespan.

Charging within the 20-80% range helps extend battery life.

It is recommended to use chargers with overcharge protection features and to disconnect the charger when the battery reaches 100%.

(2) Compatibility Between Charger and Battery

The charger should always match the battery’s rated voltage. Using an incorrect charger may cause overcharging or overheating.

Use the manufacturer’s recommended charger and avoid incompatible chargers.

(3) Environment Management During Charging

Charge in a well-ventilated area.

Avoid charging under direct sunlight or in high-temperature environments.

Do not charge in cold places; during winter, it is best to charge in a warm place.

2. Battery Discharge Management

(1) Overdischarge Prevention

Be careful not to let the battery voltage drop to 0%. Overdischarging can damage internal cells and degrade performance.

It is advisable to recharge the battery when the charge drops below 20%.

(2) Management When Storing After Discharge

When storing for a long time, keep the battery at 50-70% charge.

Storing the battery fully discharged for a long period can greatly reduce its performance.

3. Safety Management During Battery Storage

(1) Store at Appropriate Temperatures
