Battery types: w can be divided according to the different acidic electrolyte batteries (lead-acid batteries) and alkaline batteries (nickel alkaline battery) w lead-acid batteries (hereinafter referred to as lead-acid batteries): simple structure, good starting performance, low cost, Widely used in the car. w can also be divided into two types: the traditional lead-acid batteries and maintenance-free batteries just in the country in recent years, the popularity of use. w traditional batteries will occur in the course of reducing fluid phenomena car battery, car battery which is due to the price of lead and antimony grid shelves will pollute the negative plate, causing excessive water decomposition car battery 12v45ah, a lot of oxygen and hydrogen, respectively, from the positive escape the negative plate, the electrolyte is reduced. Maintenance-free batteries are lead-calcium alloy, due to the use of lead-calcium alloy batteries do gate frame, so the water generated during the decomposition charging less water evaporation is also low, with the housing sealed structure, sulfuric gases released rarely, so it is compared with traditional batteries, with no need to add any liquid, and less on the wiring trailer coupling, wire and body corrosion, anti-overcharge ability, starting current, long battery storage time and other advantages. Battery Fault Detection Guide (details) maintenance-free battery: maintenance-free battery: Also called MF batteries (ie English Maintenace-Free acronym) car battery life, its meaning is within a reasonable period of use (usually four years) without adding distilled water. Maintenance-free battery features: (1) the use of distilled water without filling up with little or filling distilled water. (2) long life (typically four years, as an ordinary battery 2,3 times). (3) internal resistance, good starting performance. (4) low self-discharge. Without supplementary charge structural features maintenance-free battery plate gate frame is made of lead-calcium-tin alloy, eliminating the side effects of antimony;?? Using PVC bag separator, to avoid the active material shedding, short-circuit plate;? adopt new safety ventilation device;? housings made of polypropylene plastic, no bottom ribs standing 20-30min after filling the electrolyte can be used, without conduct initial charge, and rarely spent sulfur charge, primarily? is a supplementary charge.
