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: What is the difference between a maintenance-free battery and a conventional battery?: As a result of maintenance-free batteries using lead-calcium alloy grille, the amount of water generated when charging less water evaporation, coupled with the shell with a sealed structure, the release of sulfuric acid gas is also very small, so it compared with the traditional battery, With no need to add any liquid, the wiring pile head, wire and body corrosion less anti-overcharge capacity, starting current, power storage time is long, by the car people welcome.

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: How to determine the battery is good or bad?: Observe the battery electrolyte is turbid, turbidity that the battery positive plate softening. Observe the bottom of the battery whether there is sediment, if the plate off the battery capacity has been inadequate. Hand hit the battery two electrode piles If you hear an empty voice that pole pile and plate break. With a thick wire short-circuit positive and negative pile observation of the battery filling holes, such as the discovery of a bubble appears that the interval has been damaged.

Q: What are the hazards of battery over discharge?: When the battery discharge current is large, the heat will become more obvious, there will be serious heat generated when the battery deformation, when the concentration of lead sulfate is particularly large, will form a larger crystal particles, that lead to the battery Internal irreversible sulfation.

Q: What are the advantages of maintenance-free batteries?: Maintenance-free battery using lead-calcium alloy grille, the amount of water generated when charging less water evaporation is low, with the shell with a sealed structure, the release of sulfuric acid gas is also very little, so with the above advantages.

Q: The role of the battery?: Battery is widely used, can be used for ups, electric cars, scooters, cars, wind energy solar systems, security, and so on.

Q: What kind of battery is divided into?: At present, we used the car battery is divided into three categories, namely, ordinary batteries, dry batteries and maintenance-free batteries three.

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: Lead-acid battery how to maintain?: After 5 hours of repair, the excess electrolyte is sucked out with a straw, and if the electrolyte is sucked out into black, it indicates that the battery is severely grounded and that the battery is difficult to repair.
