Car battery maintenance is generally about two years down the battery life, but still due to personal habits and the quality of the battery itself, while the length, but the maintenance of good can also be used for three years or even five years. What personal habits? I often take out the battery described as towers, when you want to use the battery, the battery is best to be in a fully charged state, will have the best use of state, that is when the car stalled in the battery to be fully charged state Sailing battery proxy, if the car has been in a power-hungry running state electricity generator not only not enough hair also used in the electric battery when the car was stalled, the battery power will be insufficient if the battery itself is flexible tired or unable to retain power leakage phenomenon, just like the water tower broke a hole had been leaking, leaky or not enough time, etc., the car certainly will not move or send the case to start slow speed. The car is not used properly functioning battery power alone enough electricity generator itself running the car itself, as long as the batteries recharge electric previously spent back breaker will not overcharge the battery power protection So long as the battery is fully charged every stall, coupled with the natural life that fixation of water and maintenance of long-term electric vehicle battery lead-acid batteries: the use of special techniques, structures, materials, manufacturing, acid-free leakage, gas discharge minimal amount of merchant sailing battery, long life, high capacity, shock-resistant, self-discharge, high specific energy. Capacity greater than 100 [%], the specific energy up 34-40wh / kg; high quality lead-calcium alloy, ultra-pure electrolyte, minimal self-discharge, stable performance; has a unique valve design means to avoid over-charging the internal pressure excessive use of time durable, superior safety performance; sealing reaction efficiency high sail dealers, with a long life and other characteristics; the use of multi-Pb-Ca alloy, cadmium-free sailing, in the course of the human body without toxic effects on the environment without pollution, is green, environmentally friendly products. The unique structure of the AGM separator can effectively prevent the battery from dendrite short circuit. Product performance standards: JB / T10262-2001 lead-acid batteries for electric bikes. Sailing battery quality, electric Chi to help ensure the credibility of (certified), Jiaozuo, Zhengzhou cell help provided by sailing Automotive Services Limited. Automotive Services Ltd. Zhengzhou battery help (www.dianchibang.com) is Zhengzhou, power supply, ignition system leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
