When one mentions batteries, which is what people call battery, I believe many owners are not unfamiliar. Because in a car, the battery car plays a key role. The lights, the start of the car, and many of the devices used in the car are indispensable for the battery. The quality of the battery is good or bad, which has a very big influence on the performance of the vehicle. However, the daily maintenance of car batteries, and how many years to replace once, as well as the daily use of the car and what habits can affect the battery instructions. To address this issue, I will talk about battery life with you. First of all, we must know the role of the battery. One is to start the car. At the same time, the car's battery also provides enough power for the car's lighting and some audio equipment so that they can run normally and meet people's daily driving needs. Next, we need to understand the classification of the battery, which can be broadly divided into maintenance-free and ordinary battery. Most models currently on the market use maintenance batteries. Next, we must know some habits of the car that damage the life of the battery. These habits must be avoided later. First, the use of some electric appliances and equipment in the car for a long time in the off state is a situation that many owners will encounter. For example, if they stay inside the car, they will turn off and turn on the music player or watch DVDs. Although the purpose of fuel economy has been achieved, it will put a lot of pressure on the battery, and naturally its life will be short. Second, external power supplies, such as some vacuum cleaners and some air pumps, are connected in the off state. If the car is not used for a long time, it will cause serious damage to the battery. In severe cases, it can affect the normal start-up of the vehicle. These are the topics I want to talk about with battery life. I believe you have a deeper understanding of the battery of your car. Indeed, we should always take the battery that protects our car as our task. At the same time in daily life, we must also learn more about the life of car batteries, let the battery play its normal role, so that our vehicles can run normally.

Hardness will also affect the pH value, if it is hard water, the pH value will be relatively stable, if it is soft water, the pH value is difficult to remain stable.
Hard water refers to water with a calcium ion concentration of more than 250mg/L and a basicity of more than 150mg/L.
Soft water refers to water with a concentration of calcium carbonate less than 50mg/L or a concentration of calcium chloride less than 30mg/L.
The ideal range of calcium and magnesium ions is 200-400mg/L, and the national standard is less than 450mg/L.
