Mini electric forklift is a forklift that operates by electricity, most of which are operated by storage battery. Storage batteries are one kind of batteries. Their function is to store limited electric energy and use it in suitable places. Its working principle is to convert chemical energy into electrical energy. This kind of battery is also contained in the battery of electric forklift truck. Note: Batteries should not be laid out horizontally! Because the inside of the battery is usually 22-28% dilute sulfuric acid. When the battery is being discharged, the electrolyte can submerge the plate and there is still a little space left. If the battery is transversely discharged, a part of the plate will be exposed to the air, which is very harmful to the plate of the battery. Moreover, the observation holes of the general battery or the top of the battery have vents to communicate with the outside world, so the electrolyte can easily flow out of the battery by transverse discharging.
