Zhengzhou conley of electronic power co., LTD., founded in 2000, professional development, production, sales of 2 v, 4 v, 6 v, 12 v four series and maintenance-free lead-acid battery, gel battery and electronic charger, etc. Products are widely used in security alarm system, fire alarm system, building intercom system, elevator emergency evacuation system, emergency lights, antenna, power sprayers, electronic said, children, cartoon gas mould, washing machine, rotary table, parking lock, flashing lights, traffic lights, dc panel, solar energy, wind energy, UPS, EPS, etc for electrical system.

　　Now let's talk about how often the batteries in the car change.

　　Batteries commonly used in the market are divided into two types, maintenance-free and ordinary batteries (non-maintenance-free).

　　Ordinary batteries are also known as lead-acid batteries. Their electrodes are made of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. The main advantages are stable voltage and low price. The disadvantage is that the daily maintenance is frequent. The height of electrolyte should be checked regularly and distilled water should be added.

　　The lead-acid battery is covered with many refueling outlets.

　　Be sure to add distilled water, watsons' will do.

　　Concept of maintenance free storage battery is built on lead-acid batteries, it does not need to add distilled water used in the whole cycle, it also has a shock resistant, high temperature resistant, small volume, the characteristics of uniformity. By contrast, of course, it costs more than an ordinary battery.

　　There are no maintenance-free batteries, just a health indicator for the battery.

　　When it comes to life expectancy, this is not absolute, and it has a lot to do with the environment and habits of drivers.

　　Frequent short distance driving and mileage within a few kilometers, the battery power of the battery in such driving environment is still not full, and the battery is not good for a long time.

　　If people wait for a short time, the vehicle is in the state of extinguishing the use of electrical equipment, a long time will result in the battery loss, often in the state of loss of electricity battery life is easy to reduce naturally. But many cars now have automatic power cuts, limiting the amount of time they have to turn off the lights to protect their batteries.

　　Forget to turn off the lights when parking is also a common cause of the damage of the battery, car, interior lighting, as long as a night time can run the battery run out, the second day will have to call the rescue.

　　A normal battery must have a voltage of more than 12V before starting a cold car. If the battery is out of power or the cold car starts up and finds it difficult to ignite, it is time to consider whether to change the battery.

　　Normal battery can be used for 3-4 years basically, some original car battery used for 5 years is still very healthy, for the battery life, or to form a good habit of using the car.
