Advantages of using lithium electricity:
1. Small volume, light weight, large capacity, environmental protection, no memory effect. 2. It is the power supply for portable electronic devices, but the most delicate, lithium-ion batteries in use, please note the following points. Attention: 1. Please allow tiny size deviations due to human measurement. 2. Please make sure the connection is the same type with your original battery's plug before you purchase. 3. Do not shop in temperatures over 60 ° and charge only with a specified charger or it could cause an explosion or fire. 4. if plug and voltage are the same and battery cells are different. Please don't mix them up. 5. You should use a 4.2V Li-ion battery charging standard charger. 6. the prohibition of large discharge currents. 7. It is forbidden to discharge, a single voltage battery should not be less than 2.5V. 8. It is strictly forbidden to disassemble, short circuit batteries, probably caused by a short circuit in the fire.
