Q: How to repair the battery?
Charge the battery at constant voltage. It is the beginning of the time, using 0.1C ~ 0.25C current charge, to 16.2V later, by reducing the current method to maintain the charging voltage, until the charge current drops to 0.03C when the stop charging.
Q: 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.
Q: What is the difference between a maintenance-free battery and a conventional battery?
Lead-acid battery is composed of positive and negative plates, partitions, shell, electrolyte and wiring pile head and other components, the discharge of the chemical reaction is to rely on positive electrode active substances (lead dioxide and lead) and negative plate active substances (sponge Pure lead) in the electrolyte (dilute sulfuric acid solution) under the action, which plate grid, the traditional battery lead and antimony alloy manufacturing, maintenance-free battery is made of lead calcium alloy, the former with antimony, the latter with calcium, This is the fundamental difference between the two points.
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: 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.
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: 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: 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: How does the battery increase the voltage?
Chemical energy can be converted into electrical energy device called chemical battery, generally referred to as the battery. After discharge, the internal active material can be regenerated by charging - the electrical energy stored as chemical energy; chemical energy can be converted to electrical energy again when the discharge is required. This type of battery is called a battery (Storage Battery), also known as secondary battery.
Q: How does battery activation work?
If the battery is charged, because the battery discharge itself, the active substance to activate, not add acid, but should be added pure water (no minerals and impurities in the water) is best steaming water, and now you Since the addition, you can use water to wash several times, and then use 1C current charge to 2.3 times. Then discharge, so repeated several times, will be better. So that you can remove the vulcanization.
