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: 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 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 battery does the van use?
The most obvious feature of lead-acid batteries is the top of the plastic cover can be unscrewed, there are ventilation holes above. These fillers are used to fill pure water, check the electrolyte and the use of exhaust gas. In theory, lead-acid batteries need to check the density of each electrolyte and the level of liquid, if there is a need to add distilled water. But with the upgrading of battery manufacturing technology, lead-acid battery development for the lead-acid maintenance-free batteries and colloidal maintenance-free batteries, lead-acid batteries do not need to add electrolyte or distilled water. Mainly the use of positive electrode to produce oxygen can be absorbed in the negative oxygen cycle, to prevent water reduction. Lead-acid water batteries are mostly used in tractors, tricycles, car start, etc., and maintenance-free lead-acid battery wider range of applications, including uninterruptible power supply, electric vehicle power, electric bicycle batteries. Lead-acid batteries according to the application needs to be divided into constant current discharge (such as uninterruptible power supply) and instantaneous discharge (such as car to start the battery).
Q: What are the advantages of maintenance-free batteries?
The advantage of a maintenance-free battery is that the service life is twice as long as the dry battery! And in the use of the process without maintenance! The voltage is also relatively stable.
Q: How should the battery be well maintained?
So the proposed owners if the vehicle long-term stop, but also 2 to 3 months for the battery for a charge.
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?
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: 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.
