Car battery brand, Wei Li Po battery, battery provided by Shenzhen Wei Lai Po Battery Limited. Shenzhen Wei Lai Po Battery Co., Ltd. (www.weilipo.com) is a professional "car battery, car battery, auto lead-acid batteries," the company. Since its inception, we adhere to the "honesty, sound management" approach, the courage to healthy competition in the market, so that "ABM" brand has a good reputation. We adhere to the "service first, customers first" principle, so that Wei Li Po battery has won the trust of customers congregation in batteries, and establish a good corporate image.

Battery Fault Detection Guide (details) maintenance-free battery: maintenance-free battery: Also called MF batteries (ie English Maintenace-Free acronym) automotive battery manufacturers, which means 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 charging batteries, spent very little sulfur charge? mainly supplementary charge. What is the battery and the car battery? The battery is a device composed of two materials having a difference in conductivity and the electrolyte composition. Through a series of electrochemical reactions, the battery can store and release energy. Car battery into the traditional lead-acid batteries and maintenance-free batteries. Positive and negative plates by lead-acid batteries, the separator, the case, the electrolyte and other components and wiring of the pile head, the chemical reaction whose effect is to rely on the discharge plate active material of the positive electrode active material and the negative electrode plate in an electrolytic solution (dilute sulfuric acid solution) carried out, in which the gate electrode holder is manufactured with lead-antimony alloy. Maintenance-free batteries are manufactured automotive lead-acid batteries with 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 car battery wholesale, plus shell is sealed structure, sulfuric gases released rarely, so it is compared with traditional batteries, with no need to add any liquid, for wiring trailer coupling, power storage for a long time and so on.
