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 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:The role of the battery?: Battery is a kind of battery, its role is to be able to save the limited power, in the right place to make 6v4ah emergency light battery. Its working principle is to convert chemical energy into electricity.

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?: At present, we used the car battery is divided into three categories, namely, ordinary batteries, dry batteries and maintenance-free batteries three.

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 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.

Q:What are the hazards of battery over discharge?: The battery discharge to the standard termination voltage when the internal resistance will become larger, the battery electrolyte concentration will become very thin, especially the battery plate micropores and battery plate surface these two points are almost neutral; battery over discharge because of Internal resistance will become larger, so the battery will appear inside the phenomenon of heat, the battery volume will appear fever expansion.

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: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.
