Q: How is the capacity of the battery defined?: 100AH capacity of the battery, fully charged after the 100A current discharge can be an hour to put the power finished. 50A current is 2 hours put away! 20A is 5 hours! Of course this is the theoretical value, in fact it is impossible to have a constant 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: 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?: 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: What is the meaning of the battery above 12v65Ah?: 12V is said to be the voltage, 65Ah is the current. (A is the unit of current. H is the time unit .1 hours.)

Q: How should the battery be well maintained?: Voltage check the state of the battery standard voltage should be maintained between 12.2 ~ 12.7V. If the voltage is too low should be charged, the charge should be kept small charge for a long time. Battery charging need to use a professional charger, the owner will not try to charge their own, the owner can only keep the engine running on the battery can be charged. If the battery aging should be replaced.

Q: 80ah how much battery storage capacity?: The size of the battery storage power refers to the battery capacity. Battery capacity is generally calculated in AH (safety). You 80Ah battery capacity is 80Ah, meaning that if you discharge current to 80A, you can put an hour.

Q: What kind of battery is divided into?: Ordinary battery: ordinary battery plate is composed of lead and lead oxide, the electrolyte is sulfuric acid aqueous solution. Its main advantage is the voltage stability, the price is cheap.

Q: How does battery activation work?: Always keep the battery surface clean. Found that the surface of dust and acid, it should be timely wipe, wipe can be wiped with soda water wipes wipe again, after rinse with water.

Q: Lead-acid battery how to maintain?: When receiving the battery should first check whether the phenomenon of short circuit, first short circuit repair and then fill the distilled water.
