Customer ServiceWhen a lead-acid battery is left to self-discharge (in storage or installed but seldomly used) or is exposed to excess and repeated high-rate charging (such as is the case with Start-stop vehicles), a point can be reached where the reaction at the negative plate that should convert the lead back to active material (PbSO4 back to Pb) cannot
Customer ServiceIn sealed lead-acid batteries (SLA), the electrolyte, or battery acid, is either absorbed in a plate separator or formed into a gel. Because they do not have to be watered and are spill-proof, they are considered low maintenance or maintenance-free. SLAs typically have a longer shelf life than flooded batteries and charge faster. However, they can be more expensive.

Customer ServiceSulphation is a chemical process which occurs in any lead acid battery and is a natural consequence of battery discharge. Permanent sulphation damage is a result of a battery being allowed to remain in a discharged state (<12.40V) either on or off a vehicle for an extended period and can be caused by:
Customer ServiceA lead–acid battery cannot remain at the peak voltage for more than 48 h or it will sustain damage. The voltage must be lowered to typically between 2.25 and 2.27 V. A common way to keep lead–acid battery charged is to apply a so-called float charge to 2.15 V. This stage of charging is also called "absorption," "taper charging," or
Customer ServiceThe chemical reactions are again involved during the discharge of a lead–acid battery. When the loads are bound across the electrodes, the sulfuric acid splits again into two parts, such as positive 2H + ions and negative SO 4 ions. With the PbO 2 anode, the hydrogen ions react and form PbO and H 2 O water. The PbO begins to react with H 2 SO 4 and

Customer ServiceBased on the principle of charge and discharge of lead-acid battery, this article mainly analyzes the failure reasons and effective repair methods of the battery, so as to avoid the waste of resources and polluting the environment due to premature failure of repairable batteries.
Customer ServiceVRLA batteries, sometimes called "starved electrolyte" or "immobilized electrolyte (or erroneously termed "sealed lead-acid" [SLA] or "maintenance free"), have far less electrolyte than a vented battery, and the cell container is opaque so it is impossible to see what is happening internally.
Customer ServiceThe first question, "Why does this happen?", has an easy response: lead acid battery failure is due to a hardening of lead sulfate on the electrodes or plates in each cell pack.

Customer ServiceThe lead-acid battery quickly became popular due to its ability to provide a reliable source of power. It was used to power early automobiles, as well as a wide range of other devices. However, the battery had several limitations. It was heavy, bulky, and had a relatively low energy density compared to modern rechargeable batteries. Despite these limitations, the lead
Customer ServiceThe following mainly analyzes the lead-acid battery short circuit caused by excessive charging current, charging voltage of a single battery exceeds 2.4V, internal short-circuit or partial discharge, excessive temperature rise and valve control failure, and summarizes the treatment methods of lead acid battery short circuit as follows:
Effective repair of the battery can maximize the utilization of the battery and reduce the waste of resources. At the same time, when using lead-acid batteries, we should master the correct use methods and skills to avoid failure caused by misoperation.
Lead-acid storage battery will lose part of its capacity due to self-discharge. Therefore, before lead-acid battery is installed and put into use, the remaining capacity of the battery should be judged according to the battery's open circuit voltage, and then different methods should be used for supplementary charge for the battery.
Lead-acid batteries are widely used due to their many advantages and have a high market share. However, the failure of lead-acid batteries is also a hot issue that attracts attention.
As routine maintenance, you should always check the battery electrolyte levels and ensure that the battery cells are always covered. Sealed and valve-regulated lead-acid batteries are designed in such a way that the gases released from the electrolysis of water in the electrolyte, recombine back to form water. 3. Thermal Runaway
Many of the float charge and discharge voltages of lead-acid batteries in UPS power systems have been adjusted to their rated values at the factory, and the discharge current increases with the increase of the load. The load should be adjusted reasonably during use, such as control of the number of computers and other electronic equipment.
