Why Do Electric Stackers Need To Replace The Battery

The electric stacker is a kind of reach stacker, and the battery needs to be replaced to ensure normal use. So, why do electric stackers need to replace the battery?
How lead-acid batteries work
The process of charging and discharging lead-acid batteries is an electrochemical reaction process. When charging, lead sulfate forms lead oxide, and when discharging, lead oxide is reduced to lead sulfate. Lead sulfate is a very easy to crystallize substance. When the concentration of lead sulfate in the electrolytic solution in the battery is too high or the static idle time is too long, it will “hold” into a group and form small crystals, and these small crystals attract the surrounding The lead sulfate forms large inert crystals like a snowball. When the crystallized lead sulfate is charged, not only can it not be reduced to lead oxide, but also precipitate and adhere to the electrode plate, resulting in a decrease in the working area of ​​the electrode plate. This phenomenon is called Vulcanization, also known as aging. At this time, the battery capacity will gradually decrease until it can no longer be used. When a large amount of lead sulfate accumulates, it will attract lead particles to form lead branches, and the lead branches between the positive and negative plates will bridge and cause a short circuit of the battery. If there are gaps on the surface of the electrode plate or the sealed plastic case, lead sulfate crystals will accumulate in these gaps and generate expansion tension, which will eventually cause the electrode plate to break and fall off or the shell to rupture, resulting in irreparable physical damage to the battery. Therefore, the main mechanism leading to the failure and damage of lead-acid batteries is the inevitable vulcanization of the battery itself.
At present, the service life of domestic lead-acid batteries is generally about 600 times of charge and discharge. As time goes by, the capacity of the battery will decrease. However, the motor power of the electric stacker will not change, so for the same power consumption, the smaller the battery capacity, the shorter the use time, which is commonly known as “the battery cannot be charged”. In fact, it is not that the battery cannot be charged, but that the battery is in a normal aging condition. At this time, the battery is not only not fully charged, but also requires the same amount of power (degrees) as the previous consumption, which cannot achieve normal energy conversion. Even if the old battery is fully charged, it will not last as long as the new battery. In order to maintain the normal use of the electric stacker, it is necessary to replace a new set of batteries at this time to cope with the daily use of the electric stacker.
