How should Chaowei batteries be charged?

Lithium batteries have no memory effect, so there's no special attention needed; you can charge them whenever necessary. Precautions: The main thing to note is to avoid overcharging the battery. After it shows full charge, wait about 15 minutes before disconnecting. Maintain the battery in a fully charged state. For daily use of electric bicycles, regardless of whether you ride 10-15Km, you should recharge it to keep the battery in a 'well-fed' state long-term, and charge it the same day. Leaving it unused for several days after depletion and then charging can easily lead to electrode sulfation and reduced capacity.
When I usually charge my Chaowei battery, I make sure to use the original charger and plug it into a power outlet, ensuring the environment is well-ventilated and not blocked to avoid overheating. It's best to charge when the indoor temperature is around ten degrees Celsius, as extreme cold or heat can harm the battery's lifespan. After plugging it in, let it charge for about eight to nine hours, but never leave it charging overnight, as this can cause the battery to swell, overheat, or even become unusable. I prefer to start charging when the battery level is around 20-30% to avoid deep discharge, which can damage the battery. Regularly check that the charging port is clean and free of corrosion, and that the wires have no cracks to extend the battery's service life. If the battery feels hot or emits a strange odor, stop charging immediately and contact a professional to inspect the circuit. Small daily habits like these can save a lot of trouble down the line.
Before charging, I always make sure the power supply is stable with no obstructions nearby, and the charger is securely plugged in with the interface aligned and the green light on before I feel at ease. The environment should be dry and away from fire sources, as I've seen some old batteries leak and cause accidents when charged in damp places. Charging to about 80% capacity is sufficient—there's no need to overcharge until the meter shows full and then continue wasting electricity and damaging the battery. If the car won't be used for a long time, I charge it once or twice a month to maintain battery activity and prevent it from dying. Remember not to turn on the air conditioning or stereo while charging to avoid increasing the load and causing voltage instability. Safety first—don't overlook small details. Regular maintenance and recording each charge and discharge time can help troubleshoot issues.
