We just need to excite it Give him such a big voltage It will generate a lot of current You have at least a few hundred to one ampere like this But now the battery does n’t respond no matter how hard you stimulate it Judging by my experience The battery should be broken I did n’t have this battery in my hand By the next day After I changed a battery All the malfunctions of this machine are also solved OK, so this video is here
