Warning

• To prevent battery leakage, overheating, and expansion, keep the following in mind.
• Do not throw the battery into water or fire
• Do not immerse batteries in seawater or water. Store batteries in a dry environment when not in use.
• Do not use in strong static electricity or magnetic field, otherwise it is easy to damage the protection plate.
• Do not place batteries alone near high temperature sources such as open flames or heat sources.
• Direct short circuit of batteries with metallic substances is prohibited.
• Do not touch or fall heavy weight batteries.
• Do not weld batteries directly or punch holes on batteries with nails or other sharp objects.
• If the battery gives off odor, heat, deformation or other abnormalities, remove the battery immediately or stop using the charger.
• If the battery leaks and the electrolyte enters your eyes, do not rub your eyes. Rinse your eyes with clean water immediately and seek medical treatment. Otherwise, your eyes may be injured.
• When the battery is stored for a long time or loaded into the host, it is recommended that the customer charge and discharge it once every 3 months, and then charge it to the semi-charged state (charging method: 0 .33C charge and 0.33C discharge).
