Q:What are the technical parameters of the battery?
The main performance parameters of the battery are the following: model; voltage; battery capacity; battery type, such as lead-acid batteries, alkaline batteries, lithium batteries, solar cells, fuel cells.
Q:How should the battery be well maintained?
Electrolyte density This is to evaluate whether the battery charge is normal, whether the aging of the important parameters, the use of density meter or electrolyte density tester can be measured. If the electrolyte density is too small, you need to charge. And the electrolyte concentration is too thick or too thin to a certain extent, it means that such as the occurrence of plate vulcanization, short circuit or overcharge phenomenon, this time on the need for maintenance.
Q:Lead-acid battery how to maintain?
Along the battery cover on the exhaust hole, open the battery cover plate, some of the battery cover is APS adhesive, and some batteries are buckle connection, pay attention to open the cover when the cover plate The At this time you can see the six exhaust raft rubber cap.
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: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:What battery does the van use?
General use of lead-acid batteries. Electrode is mainly made of lead and its oxide, the electrolyte is a sulfuric acid solution of a battery. English: Lead-acid battery Discharge state, the main component of the cathode is lead dioxide, the main component of the negative lead; charge state, the main components of the positive and negative are lead sulfate. Divided into exhausted batteries and maintenance-free lead-acid batteries.
Q:How to determine the battery is good or bad?
Instrument test: the general use of battery discharge tester, the test instrument two positive and negative clamp were holding the battery positive and negative electrodes, press the test button to observe the test instrument instructions.
Q:How to deal with waste batteries?
The rest of the various types of waste batteries are generally shipped to a special toxic, hazardous landfill, but this approach not only cost too much but also cause waste, because there are many useful raw materials available.
Q: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.
Q:Maintenance-free battery how to detect it?
Do not always check the color of the electric eye for maintenance-free batteries. Green for the full power; black for the lack of electricity, need to be added to charge; gray or light yellow for the electrolyte is insufficient, because maintenance-free battery can not add liquid, should immediately replace the battery.
