With the rise in temperature, the temperature in most areas is now around 30 degrees, or even more than 30 degrees, when the activity of the battery reaches a relatively ideal state. Most 20AH batteries have a discharge time of more than 120 minutes. The long discharge time is 140 minutes.

This is also why some batteries do not feel very good when it is cold, and in summer, the car's range is significantly improved. As netizens say: full of blood resurrection. This is because the discharge efficiency of lead-acid batteries has a considerable relationship with temperature.
The ideal discharge temperature for a battery is around 25 to 30 degrees. In much of the South, summer temperatures are in the 30s. Of course, if it is too high, it is also bad for the battery. Above 35 degrees, charging in these temperatures requires great care. The charger may stay red and not turn green. This happens with many new batteries, too. Because you keep charging the battery, the battery tends to get hot. We need to pay great attention to this.
It is recommended that you go to the hardware store to buy a kind of timing socket, this socket is not expensive, it should be about 20 dollars. It can be set up for as little as a few minutes to as long as ten hours. We can adjust the charging time of the outlet. Summer generally set 7-8 hours on the line, 8 hours is enough.
Summer itself is relatively hot, if you find that the car battery has been drum deformation, it is recommended that you do not use it, especially the more serious the deformation of the same, the battery may explode.
When we charge the electric vehicle, we should avoid being exposed to the hot sun to charge, and do not put the charger under the seat cushion to charge, because the front space of the seat cushion is too small, the air is not circulating, the charger is not good for heat, and it will be seriously heated. Try to place the vehicle in a cool and ventilated place to charge.
Charging in the hot weather charging display light will not directly show the green light, if the full charge will show the green light, in the summer charging the battery is easy to be filled, the normal electric vehicle charging is generally full of about eight hours, if in the summer at most six hours is full, charging when the red light, but full of the display will show the green light.
