Why does electric car battery red light always on while charging?

In recent days, my electric bicycle has been charged at a red light, and the plastic shell of the battery is hot, powerless to ride, and the total distance is not as far as before. The battery has only been used for 8 months, even though it is a 36V electric bike. what should I do?

Timely maintenance treatment can be restored. Method is: Add 15ML of pure water to the battery and charge it with a current of 4 ampere. Charge it until the current drops to 1 ampere, and leave it there for 2 hours. Measure the voltage of each battery and make sure it is 13.3. If one of them doesn't get there, charge the battery until it does.Then string the batteries together.

High temperature hot weather in summer, people feel uncomfortable so dose the battery.Batteries lose water badly in the summer and are thirsty like people.

So in the summer you should pay attention to the following points when charging the battery can properly avoid battery belly.

1, Once it is found that the battery charging time is significantly longer (generally 6-8 hours). Don't turn on the light after charging all night, please take off the charger as soon as possible. Check your charger at a professional location. A better charger will do you a lot of good.

2, Charging turns the green light time slant long battery, has detected the charger to have no problem, that is the battery has the problem. The battery loses a lot of liquid. Fluid can be added appropriately,but be careful not to add too much. (You’d better look for professional person to add) Then leave it for one day before recharging.

3, In addition to losing too much fluid, it is possible that one of the batteries is short-circuited. A multimeter can be used to measure the voltage of each battery. If found to have low voltage of the block is a short circuit. It's time for a new battery.

In hot summer, most of the phenomenon is usually riding well, but suddenly broken after a charge, open the battery shell found that the battery has part or all deformation. The battery is not working and must be replaced!

Battery scrap before, however, is a symptom. Such as the original charge when the battery is not hot, after using a year or so (or even a shorter time),the battery charging in the fever(with the hand to touch the battery shell) can be felt but most users though surprised but not too care about, because it did not impede cycling, most of the day in the summer the above situation happened suddenly.

So the usual maintenance for electric car users is very important, but most people don't know how to maintain. Some users are told that the battery is maintenance free when they buy an electric car, but that the battery electrolyte is made into a gel or that the water loss is smaller than the general battery sealing performance.However,the battery is used for a year or so (or longer or shorter time), the formation of sulfates crystal on the battery plate is inevitable, the resistance increases the heat of charging, the water loss increases the vulcanization and the vicious cycle is inevitable! Electric car batteries need maintenance!
