Welcome to inquire! Contact: Mr. Liu. Battery Fault Detection Guide (details) maintenance-free battery: maintenance-free battery: Also called MF batteries (ie English Maintenace-Free acronym), 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 plates grid frame with lead calcium tin alloy car battery, eliminating the side effects of antimony;?? Car battery separators using PVC bag manufacturers can avoid the shedding of active material, short-circuit plate;? the use of new safety venting device;?? housings made of polypropylene plastic, no bottom ribs standing 20-30min after filling the electrolyte can be used to buy a car battery, no initial charge were also Few spent sulfur charge, the main charge is added. What factors will affect the life of the battery? In addition to the battery design and manufacture of the product itself, the quality of a new car battery, battery of actual life associated with many factors. Climatic conditions: high temperature region, the actual battery life will be significantly shorter. The output voltage of the generator: too high will cause excessive charging, the pressure is too low to cause insufficient charging. Owner's driving habits: When the engine is not running, prolonged use of the car's electrical, or often forgot to turn off appliances. Error adaptation: Optional capacity will shorten the life of the battery is too low. Vehicle leakage serious - serious leakage will significantly increase the burden on the battery, greatly shorten life.
