How to prevent car battery loss? Professionals: You cannot charge at idle speed, you must refuel at 2,000 rpm.

The Spring Festival in 2020 is a bit special. In order to cope with the new coronavirus epidemic, many people "quarantine at home" in accordance with the prevention and control requirements, and the scope of activities is only in the living room, bedroom, kitchen, etc., which is 100 square meters.

As a result, many car professionals in the circle of friends have given many warm tips to prevent battery loss, such as: Be sure to turn on the ignition every two or three days and let the engine run for a few minutes to prevent battery loss. If it is parked for more than five days, it is best to disassemble the negative terminal of the battery, etc. Some even say that the engine cannot charge the battery when it is idling, so you need to step on the accelerator to maintain the speed above 2000 rpm (some say 2500 rpm). So can the above statements prevent car battery loss?

Hydrogen Cloud Chain believes that these statements are not reliable and may even damage the car! So how should we avoid and correctly deal with the battery loss when our car is left downstairs or in the basement of the community for more than half a month or even longer? Hydrogen Cloud Chain believes that it can be easily done from the following three aspects solve!

Disconnect all electrical equipment in the car

In general, due to the vehicle being parked for a long time, the direct loss of the battery is the electrical equipment in the car, although most of them use The electrical interface is also powered off. Due to design problems, there are still some individual models that can still supply power after the vehicle is turned off, such as the original vehicle driving recorder, electronic anti-theft lock, etc. Therefore, in order to avoid battery loss when the vehicle is parked for a long time, the most direct way is to turn off all electrical appliances on the vehicle and unplug all external power supplies.

Disassemble the negative terminal of the battery

The car manual has relevant descriptions of long-term parking of the vehicle. In principle, a car parked for more than 15 days is considered long-term parking. In order to avoid battery loss, you can Disconnect the negative terminal of the battery. However, Hydrogen Cloud Chain believes that as long as the vehicle is parked for more than five days, it is best to disassemble the negative electrode of the battery.

Start the vehicle at intervals to charge the battery

If the car is parked for a long time, under normal conditions, the battery will lose more than 1 charge every 24 hours, and the battery will basically lose about 1% of its power. It takes about three months. However, the phenomenon of battery loss will aggravate the damage to the battery, leading to a reduction in battery capacity and service life, and ultimately lead to early scrapping of the battery. Therefore, Hydrogen Cloud Chain recommends that you start your vehicle every other week or so, idling normally for 20 minutes or driving normally for 10 minutes to easily charge the battery.

Some people may not care about parking their vehicles for a long time, but they will definitely regret it when problems arise. Although the car is just a means of transportation for us and does not need to be cared for as carefully as preserving a classic car, as long as we are more careful and pay more attention, we can prevent it from falling off when we need it.
