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:How should the battery be well maintained?
Battery Pile The battery pile head is part of the battery connected to the vehicle. If the corrosion or poor connection occurs, the battery will work poorly. The owner can check whether there is a white powder near the pile head, which is the sign of the pile head corrosion. If the white powder is more, you can use boiling water to burn it off, and then its anti-corrosion treatment, in the pile head smear some grease or preservatives can, but should not be too much to apply, so as not to affect the use.
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.
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:What is the meaning of the battery above 12v65Ah?
12V is said to be the voltage, 65Ah is the current. (A is the unit of current. H is the time unit .1 hours.)
Q:How does the battery increase the voltage?
Chemical energy can be converted into electrical energy device called chemical battery, generally referred to as the battery. After discharge, the internal active material can be regenerated by charging - the electrical energy stored as chemical energy; chemical energy can be converted to electrical energy again when the discharge is required. This type of battery is called a battery (Storage Battery), also known as secondary battery.
Q:What is the difference between a maintenance-free battery and a conventional battery?
Different materials will produce a different phenomenon: the traditional battery in the course of the use of the phenomenon of liquid reduction occurs, because the antimony on the grid will pollute the sponge on the negative plate of pure lead, weakened after the full charge of the battery Electromotive force, resulting in excessive decomposition of water, a large number of oxygen and hydrogen, respectively, from the positive and negative plates to escape, so that the electrolyte reduced. With calcium instead of antimony, you can change the fully charged battery back electromotive force, reduce the overcharge current, liquid gasification rate decreases, thereby reducing the loss of electrolyte.
Q:How to repair the battery?
Charge the battery at constant voltage. It is the beginning of the time, using 0.1C ~ 0.25C current charge, to 16.2V later, by reducing the current method to maintain the charging voltage, until the charge current drops to 0.03C when the stop charging.
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:What are the hazards of battery over discharge?
Crystalline conductivity is poor, and bulky, will clog the pores of the battery plate, affecting the battery electrolyte penetration and exchange, but also further increase the battery resistance, a long time will prevent the battery power and chemical energy Of the reversible conversion, resulting in poor recovery of the battery charge, the battery was seriously damaged, or even unable to repair until scrapped.
