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 are the technical parameters of the battery?: Battery capacity is defined as ∫ t0tdt, theoretically t can be infinite, but in fact when the battery discharge is lower than the termination voltage continues to discharge, which may damage the battery, so t value is limited, the battery industry, in hours (h) Battery sustainable discharge time, feel the C24, C20, C10, C8, C3, C1 and other nominal capacity value.

Q: 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.

Q: What are the hazards of battery over discharge?: Excessive discharge can seriously damage the battery's electrical performance and cycle life.

Q: Maintenance-free battery how to detect it?: When using a maintenance-free battery, it is easy to think that maintenance-free is the idea that no maintenance is required. Maintenance-free Although maintenance costs and times can be reduced, but for the appearance of the clean-up is essential, so that "maintenance-free" more point to the battery inside.

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 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 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: What is a maintenanceable battery?: It also has a shock, high temperature, small size, self-discharge characteristics. Life is generally twice the ordinary battery.

Q: Lead-acid battery how to maintain?: After 5 hours of repair, the excess electrolyte is sucked out with a straw, and if the electrolyte is sucked out into black, it indicates that the battery is severely grounded and that the battery is difficult to repair.
