Q:How should the battery be well maintained?
Voltage check the state of the battery standard voltage should be maintained between 12.2 ~ 12.7V. If the voltage is too low should be charged, the charge should be kept small charge for a long time. Battery charging need to use a professional charger, the owner will not try to charge their own, the owner can only keep the engine running on the battery can be charged. If the battery aging should be replaced.
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:How to repair the battery?
To the battery in accordance with the 0.1C current discharge, record the discharge time. Its discharge current multiplied by the number of hours of time, is the battery repair capacity. If the Chongqing battery capacity to reach the nominal capacity of more than 70%, the end of the repair.
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: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 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:80ah how much battery storage capacity?
Is 80AH. Understood to discharge at 80 amps for about 1 hour (but not to say that after 1 hour is finished, there is still electricity). In theory, this is your battery power.
Q:How is the capacity of the battery defined?
100AH capacity of the battery, fully charged after the 100A current discharge can be an hour to put the power finished. 50A current is 2 hours put away! 20A is 5 hours! Of course this is the theoretical value, in fact it is impossible to have a constant current discharge.
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 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.
