CR2016 battery

　　How to maintain a CR2016 battery and what should you pay attention to when adding water?

　　If you want to maintain the CR2016 battery, you can turn off the lights and air conditioner before parking, close the windows before turning off the engine, and move the vehicle frequently when parked for a long time. In addition, when adding water to the battery, be careful not to touch it with metal. The replenishing liquid must be dedicated. Measure the resistance value before use. Drinking pure water cannot be used casually. The relevant content is introduced in detail below.

　　1. How to maintain car batteries

　　1. Before parking, turn off the lights and air conditioner.

　　Some older models do not support the automatic power-off function after the engine is turned off, so you need to manually turn off the lights and interior reading lights before turning off the engine. If you need to find something in the car or need lighting, you can use your mobile phone or flashlight for lighting, so as not to turn on the reading light and forget to turn it off, causing the battery to lose power. There are also many people who tend to ignore the air conditioning system. After the engine is turned off, the air conditioner remains on. Although there is no energy, the air conditioner cannot be started. However, when we start the car again, the air conditioner will run automatically, which puts a heavy load on the battery. If it is very large, it will also affect the life of the battery.

　　2. The car also needs to be driven around frequently.

　　Even if all the electrical systems in the car are turned off, the battery power may be exhausted after the car is parked for a long time. Therefore, even if the car is left idle at home for a long time, the engine must be started regularly. , it is best to sneak on the road for more than 20 minutes, so as to ensure that the battery has sufficient time to charge.

　　3. Wipe it for better health

　　Open the hood regularly and wipe the positive and negative terminals of the battery with a damp cloth (that is, the two exposed silver cylinders connected to a black wire and inserted on the surface of the battery). Regularly wipe the dust, oil, and white powder covering the electrode head with a damp cloth. This not only cleans it, but also effectively reduces the accumulation of white acid-etched powder and protects the battery.

　　4. Before turning off the engine, close the windows

　　The car's windows and sunroof switches are powered by batteries, so it is best to close all windows before turning off the engine instead of closing them after turning off the engine. You can even close the windows by pressing and holding the lock button after leaving the car.

　　2. Precautions for replenishing water in car batteries

　　1. Do not open the control valve for too long. If a small current repair solution is adopted, the control valve should be closed immediately, otherwise impurities in the air will enter the battery and affect the battery life;

　　2. It is best to replenish water at the end of battery charging, so that the water can be replenished at once, and it is not easy to add too much and it is not easy for impurities to enter.

　　3. The so-called "replenishing liquid" must be dedicated, and the resistance value must be measured before use. Drinking pure water cannot be used casually.

　　4. Be sure to take good care of the control valve and keep it clean.

　　5. It is absolutely forbidden to touch the replenishing fluid with metal.

　　After each replenishment, the battery is in an overcharged state to change the battery from a 'quasi-liquid' state to a 'liquid-poor' state, and this overcharging is beneficial to increasing battery capacity.
