18650 lithium battery 3.7 v

　　How to better use 18650 lithium battery 3.7 v?

　　1. Timeliness of charging:

　　(1) Lithium batteries are generally half-charged before leaving the factory. The first time you ride a bike, it's a good idea to fully charge the battery. One is that self-discharge will reduce the charge of lithium batteries, and the other is that it can activate the active materials in it.

　　(2) Do not drain the battery every time you ride, because over-discharge will cause great damage to the lithium battery. Long-term overcharge and discharge will reduce the number of battery cycles by 3 times. At least when the battery scooter prompts that the battery is too low during riding, you must resolutely stop riding and recharge the lithium battery.

　　2. Timeliness of charging:

　　(1) It is reasonable to charge lithium batteries anytime and anywhere, even if the battery has 50% power consumption before charging. This is because it is different from nickel-metal hydride batteries, which have memory while lithium batteries do not.

　　(2) Avoid overcharging the battery. Stop charging when the battery charging indicator light comes on.

　　3. Charge to compensate for self-discharge:

　　If the battery is not used for a long time, it must be charged once within 60 to 90 days, because the best storage state of lithium batteries is half-charged storage (that is, stored between 40% and 60% of the allowed capacity of the battery). We know that the maximum voltage of lithium battery is, therefore, the best storage voltage is in the middle, when the volume is almost half.

　　4. Original battery charging equipment:

　　When possible, use the original lithium battery charger for battery charging. The genuine charging head has strong compatibility and moderate battery charging rate. There are some fast charging stations now, and it is recommended not to use too many. There is a reason to use it once or twice a year. Charging the battery with excessive current will also cause great damage to the internal structure of the battery.

　　5. Temperature environment during storage:

　　The temperature environment of polymer lithium batteries is relatively wide, ranging from -20℃ to 45℃, but in fact the best temperature is indoor temperature. From the perspective of aging, temperature may be the main reason for the gradual decrease in lithium battery capacity. For my country with large regional temperature differences, North China needs to develop cold-resistant lithium batteries, and coastal areas need to develop heat-resistant lithium batteries.

　　6. Strictly implement the frequently asked questions in the guidelines:

　　When lithium batteries are not in use, they should be placed in a cool and cool place to prevent high temperature and humidity, and try to avoid riding on rainy days. Even when riding a bicycle, you must maintain it to prevent water leakage from the lithium battery.
