Battery maintenance is real.

The range of batteries is very wide, including lithium batteries and lead-acid batteries. At present, the repair technology is aimed at lead-acid batteries. That is, the most common maintenance-free batteries and water batteries in electric vehicles and the maintenance-free batteries and water batteries used to start ignition in automobiles.

Lead-acid battery, after a period of use, will appear the phenomenon of capacity decline, which is caused by battery vulcanization. For these batteries, the battery repair machine can solve the vulcanization of batteries well, so as to repair most of the phenomena such as insufficient battery capacity and decreased battery capacity. So battery maintenance is real.

Some batteries are damaged by logistics, such as pole breakage and short circuit of pole group, which need to be repaired manually. We can train this part of technology for free on site.
