FAQ

What are the technical parameters of the battery?

Usually the capacity of the power supply is expressed by kV · A or kW. However, as a power supply VRLA battery, the use of security (A · h) that its capacity is more accurate.

How to determine the battery is good or bad?

If less than 9V but the pointer is in a certain value does not move that the battery is in a state of loss, need to add charge.

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.

How does the battery increase the voltage?

With the same battery pack in series; if the required current is relatively small, you can use DC-DC module.

How to deal with waste batteries?

Laboratory recycling method: ordinary dry battery is cylindrical, the outer cylinder made of zinc, the zinc cylinder is the battery negative; tube central carbon rod for the positive; tube for the manganese dioxide, ammonium chloride and chlorination Zinc.

What are the advantages of maintenance-free batteries?

Maintenance-free battery because of its normal charging voltage, the electrolyte only produce a small amount of gas, so throughout the use of the need for the addition of distilled water, in the normal charging system, do not need to remove the charge from the removal. But in the maintenance of the proportion of its electrolyte should be checked.

How is the capacity of the battery defined?

General circuit has a battery protection circuit, once the battery voltage is less than 10.8V will automatically cut off the electricity to prevent the battery because of over-discharge and damage. (Nominal value of 12V battery internal six cell grid) with the battery discharge current multiplied by the discharge time to express how much energy the battery can store, is a very image of a measure. The greater the value of the battery, indicating that the battery can store more energy. But does not mean that the battery can use such a large current discharge.

Lead-acid battery how to maintain?

Open the rubber cap, exposing the exhaust raft, you can see the battery inside, some of the battery exhaust cutting can be unscrewed.
