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: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:Battery 200ah / 104 what does that mean?
This should be refers to 2V200AH battery 104, power with the 220V.
Q:How does battery activation work?
Always keep the battery surface clean. Found that the surface of dust and acid, it should be timely wipe, wipe can be wiped with soda water wipes wipe again, after rinse with water.
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 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: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:What is a maintenanceable battery?
It also has a shock, high temperature, small size, self-discharge characteristics. Life is generally twice the ordinary battery.
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: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.
Our pioneering efforts have earned us 10 national patents so far. In fact, we have the second largest number of patents among listed suppliers in mainland China.We also been offering complete solutions for LiFePO4 battery pack buyers for over six years. Customers especially enjoy our battery pack, battery management system and charger solution.
