A: Yes, it is avaliable.

Q: What is your payment terms?
A: Sample payment through Paypal or Western Union, and mass order by T/T or L/C.

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 hazards of battery over discharge?: The battery discharge to the standard termination voltage when the internal resistance will become larger, the battery electrolyte concentration will become very thin, especially the battery plate micropores and battery plate surface these two points are almost neutral; battery over discharge because of Internal resistance will become larger, so the battery will appear inside the phenomenon of heat, the battery volume will appear fever expansion.

Q: Maintenance-free battery how to detect it?: Keep the battery surface clean. If the discovery of solid oxide on the pole, it should be timely with hot water pouring, to be removed, so as not to affect the pole and the terminal between the continuity. After cleaning up, wipe the battery surface, in the pole and the terminal cast on the butter to ensure that the pole is not oxidized.

Q: 80ah how much battery storage capacity?: 0AH storage is 80AH ah If the actual storage capacity will have to see the brand. I have seen 100AH only 24 pound. This is not even 60AH.

Q: The role of the battery?: Battery is a kind of battery, its role is to be able to save the limited power, in the right place to make 6v4ah emergency light battery. Its working principle is to convert chemical energy into electricity.

Q: What kind of battery is divided into?: Ordinary battery: ordinary battery plate is composed of lead and lead oxide, the electrolyte is sulfuric acid aqueous solution. Its main advantage is the voltage stability, the price is cheap.

Q: How does the battery increase the voltage?: The so-called battery is the storage of chemical energy, if necessary, the release of electrical energy of an electrical chemical equipment.

Q: Battery 200ah / 104 what does that mean?: This should be refers to 2V200AH battery 104, power with the 220V. Lead-acid battery nominal voltage is 2V / (each or monomer), but in fact will be higher than 2V, so the actual use and charging equipment for the matching will use 104, also useful 103, also useful 108 Only.

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?: After passing the test, cover the exhaust cutting, pay attention to restore the filler, cover the battery cover, if the cover is glued, then glue bonding.
