Hangzhou 24V forklift battery using basic flatbed truck, stacker, lifting platform, is one of the most widely used batteries, which lead to cavernous as anode, two lead oxide as the cathode, we put the two kinds of substances known as active material, sulfuric acid aqueous solution as electrolyte. The electrochemical reactions are involved in the cell the. The principle of chemical reaction of lead-acid battery is as follows

Negative reaction: Pb+HSO4- PbSO4+H++2e

Positive reaction: PbO2+2e+HSO4-+3H+ PbSO4+2H2O

Electrode reaction: PbO 2 +2 +2HSO +Pb 2Pb SO 4- 4 H 2 H+ 2 O (+2)

State of charge discharge state from the reaction principle can be seen in the discharge, the anode material is generated with lead sulfate sulfuric acid in the electrolyte, so called Double sulfation reaction". Under normal circumstances, the lead sulfate generated by the structure of osteoporosis, and its crystal is very small, very high electrochemical activity, spongy lead sulfate and lead this very high activity can be re generated positive in charge under the current two lead oxide and cathode. Through this stable reversible process, the battery can store the electric energy and release the electric energy. Experienced users are aware that the cost of the battery is the largest consumption of electric bicycles, so users are very concerned about the extension of battery life. First of all, it is necessary to assume that the charger is not a problem, the user is the right to use the battery life is critical.

The use of a certain period of Hangzhou forklift battery, in order to avoid subsequent use of vulcanized etc., lead sulfate in a period of time after the formation of higher activity, if in this period of time is not timely charging or charging fully, so it is not timely into positive and negative active material of lead sulfate will be in low temperature again re crystallization, precipitation in crystalline lead sulfate, so again and again, makes the crystal grain increasing, conductive performance is poor, difficult to be dissolved, charging is difficult to restore the lead sulfate crystals, namely irreversible salt (mentioned in this manual refer to such salt salt). There are many reasons for battery failure, such as the deadly grid electrode corrosion and electrode grid serious deformation, loss of electrode active material, battery internal short circuit or open circuit and other physical and chemical reasons, but the statistics show that the failure of the vast majority of batteries are caused by irreversible sulfation of the electrode active material. This papersummed in charge to recover two of lead oxide and spongy lead, with great harm to the battery: it is a consumption of active substances, effective capacity of the battery is reduced, so long will lead to battery scrap; not only itself when charging is difficult to restore, and void clogging of the porous electrode, prevent the electrolyte through increased resistance; charge and discharge heat more, increasing the cell temperature will increase the plate corrosion and deformation of the active substance to lead off the cell structural scrapped; the charge efficiency is decreased, the charging time is prolonged, and the energy waste caused by time;

In the electrolysis of water phenomenon is more serious, because the battery is easy to dehydration dry up; capacity decline, output power shortage, in order to maintain a certain output can only increase the depth of discharge, will cause more severe sulfation, forming a vicious spiral; due to consumption of sulfuric acid, resulting in decreased electrolyte density, reduce the large current discharge capacity, performance decline. Including the battery in the process of using the main reasons of the formation of irreversible sulfation: depth of discharge and discharge current, no charge in time or lack of charge; battery battery performance is not the same, there are differences over large capacity performance behind the battery; for a battery group was significantly lower than other batteries, causing the the battery voltage drops, when charging the battery due to backward first to be full of other batteries still need to charge and discharge the charge form, because the first behind the battery is empty, so as to form a discharge, resulting in sulfation further intensified, the backward degree is more serious, forming a vicious spiral. fork
