Battery Charging Instructions

1. Before first use, charge the battery fully to 100%. Then let it discharge to 15% and charge it again.

2. Charge the battery at an ambient temperature between 10°C and 30°C. The operating temperature is between 0°C and 40°C

3. This battery is Lithium technology. Discharging it completely can be a problem because it pushes her to the limits of her endurance. Instead, proper usage dictates that you periodically discharge to 20%-30% and charge frequently.

4. The battery should not only stay on the power supply but be used as often as possible.

5. If you decide not to use your battery for a period of about 3 months, the battery should be charged to at least 40% and stored in as cool and dry an environment as possible.

6. Temperature is the battery's worst enemy, so don't leave your device in your car during the summer.

7. Do not modify, remanufacture, or attempt to insert foreign objects into the battery. Also, do not expose the battery to water or other liquids. Batteries may explode if damaged.
