A. How to properly charge a battery

• Charge between 20% and 80% to maximise lifespan.

• Avoid prolonged charging at 100%.

• Never allow a battery to fully discharge.

• Use only a compatible charger.

B. How to store a battery

• Ideal storage charge level: 40–60%.

• Recommended temperature: 10–20°C.

• Do not leave the battery in direct sunlight, in a car, or in a humid environment.

C. How to extend battery lifespan

• Avoid full charge and discharge cycles.

• Prefer shorter, more frequent charging sessions.

• Do not use a charger more powerful than required.

4. Can a more powerful charger be used?

No, this can damage the battery. Always use a charger with the same voltage and the recommended current (amperage).

5. Est-ce dangereux de laisser une batterie branchée toute la nuit ?
