What is a battery car that is too hot to charge for a long time?

The use of the battery depends on the motor power of the battery car. Generally, the service life of batteries below 350W is above 1 year, and it is normal for batteries below 2 years. If the motor is above 500W, it's hard to say. A 20Ah battery can only last for 8 months to a year.

There are several points to judge whether the battery can continue to be used: 1. The number of charge and discharge cycles is generally about 500-600. 2. Whether the continuation class exceeds 60% of the new battery. 3. Whether the matching group is balanced. 4. Whether there is vulcanization or bulging caused by underfilling or overcharging.
