NOTE: Never charge the battery module to less than 2.5V. A battery module that has dropped below this voltage must be replaced and the old module disposed of - charging / recharging the module below 2.5V is dangerous. Lithium-ion batteries can be dangerous if used incorrectly. Incorrect use can result in fire or explosion due to short circuiting.
Do not charge the battery with the wrong poles. Never short-circuit the battery, or put the battery pack in your pocket with keys or other metal objects.
Do not disassemble the battery. If the Li-Ion battery module is deformed, it should be disposed of. Do not immerse the battery in water and do not allow the module to come into contact with liquids.
Avoid use in environments with very high physical vibration and/or shock. Do not throw the battery module into a fire.
Keep the battery module out of the reach of children. Do not use a modified or damaged charger when charging and check the charging voltage before using the charger.
Do not leave the battery module in the charger for more than 12 hours. Store the module in a cool, dry and well-ventilated environment. When disposing of the battery module, comply with local regulations.
When assembling a battery from modules, do not use soldering to connect the modules, but use spot welding - soldering onto the module will cause heat damage to the modules.
