Battery is a kind of battery, its function is to store limited electric energy and use it in the right place. Its working principle is to convert chemical energy into electrical energy. This battery is installed in the battery of the electric forklift. It should be noted that the battery is best not to be placed horizontally! Because the battery is generally 22~28% dilute sulfuric acid. When the battery is placed upright, the electrolyte can submerge the electrode plate, and there is still a little space. If the battery is placed horizontally, some electrode plates will be exposed to the air, which is very unfavorable to the electrode plates of the battery. Moreover, the observation hole of the battery or the exhaust port at the top of the battery is communicated with the outside, so the electrolyte is easy to flow out when the battery is placed horizontally.
