Q: How to repair the battery?: Pry open the adhesive or heat-sealed battery cover, reveal the maintenance-free battery rubber exhaust valve, carefully remove the exhaust valve, save, observe the battery internal situation. Add 0.1% to 0.5% of the electrolyte to the battery, just to the battery above the flow of electrolyte. At the same time, check whether the black impurities, if there are obvious black turbid impurities, indicating that the battery plate has been significantly softened, the possibility of battery repair is relatively small. If there is no black muddy impurities, need to wait 4 hours later, the water fully into the battery. If it is only because the deactivation time is long and cause the battery capacity to decline, do not need to carry out this step operation, should go directly to step 3 pre-charge.

Q: How is the capacity of the battery defined?: The capacity of the battery unit is AH (safety) is the product of current and time.

Q: What is the difference between a maintenance-free battery and a conventional battery?: Lead-acid battery is composed of positive and negative plates, partitions, shell, electrolyte and wiring pile head and other components, the discharge of the chemical reaction is to rely on positive electrode active substances (lead dioxide and lead) and negative plate active substances (sponge Pure lead) in the electrolyte (dilute sulfuric acid solution) under the action, which plate grid, the traditional battery lead and antimony alloy manufacturing, maintenance-free battery is made of lead calcium alloy, the former with antimony, the latter with calcium, This is the fundamental difference between the two points.

Q: What are the technical parameters of the battery?: The main performance parameters of the battery are the following: model; voltage; battery capacity; battery type, such as lead-acid batteries, alkaline batteries, lithium batteries, solar cells, fuel cells.

Q: 80ah how much battery storage capacity?: The size of the battery storage power refers to the battery capacity. Battery capacity is generally calculated in AH (safety). You 80Ah battery capacity is 80Ah, meaning that if you discharge current to 80A, you can put an hour.

Q: What kind of battery is divided into?: Maintenance-free battery due to its own structure on the advantages of electrolyte consumption is very small, in the life of the basic need not add distilled water. It also has a shock, high temperature, small size, self-discharge characteristics of the general life is generally ordinary Twice the battery. There are two kinds of maintenance-free batteries on the market.

Q: How does the battery increase the voltage?: With the same battery pack in series; if the required current is relatively small, you can use DC-DC module.

Q: What is a maintenanceable battery?: This is relative to a maintenance-free battery. Maintenance of the battery needs to be supplemented with electrolyte to ensure work, while maintenance-free is not required.

Q: How does battery activation work?: If the battery is charged, because the battery discharge itself, the active substance to activate, not add acid, but should be added pure water (no minerals and impurities in the water) is best steaming water, and now you Since the addition, you can use water to wash several times, and then use 1C current charge to 2.3 times. Then discharge, so repeated several times, will be better. So that you can remove the vulcanization.

Q: Lead-acid battery how to maintain?: When receiving the battery should first check whether the phenomenon of short circuit, first short circuit repair and then fill the distilled water.
