Electric car battery provides energy lorry energy , electric cars mainly uses a combination of lead-acid batteries . Cargo bike nickel-metal hydride batteries and lithium-ion batteries also have some lightweight folding electric car to use.

1 . Lower than the market average wholesale price determined not to buy batteries .
2 . Not more than two years after the market test of the product .
3 . No electric car battery with car manufacturers are determined not to buy it.
4 . Expensive batteries, if not large production , determined not to buy .
5. Changes in national standard-sized batteries determined not to buy .
6.5A discharge , 30 seconds when the voltage is higher than 12.68V is determined not to buy more than 90 % of the short-lived batteries.
The easiest way to detect the battery : 5A discharge voltage is below 12.63 and 30 seconds , three minutes before the voltage rise, not fall , but rise more, the better the quality.
