How to change the battery in a dead car key

1How to change the battery of a dead car key

New drivers need to know more. For example, the car key, although it is a small accessory, but it affects the whole car driving. When you run out of power, you don't have to go to a 4S store for a "high-priced" repair and replacement, you can easily do it yourself. After all, 4S store replacement parts are expensive, high labor costs, or buy their own button battery good.

The operation is also very simple, the car key shell out of the new battery can be replaced. However, some batteries must be replaced shortly after. Some new car key bands have many functions, but the remote control distance of ordinary batteries is shortened and can only be used in close proximity. This is something that many novice drivers struggle with.

How to choose the right button battery is the key. There is absolutely nothing wrong with buying a brand. For example, Funan is a famous battery brand in China. Funan Group launched the world's first graphene high-capacity button battery. Graphene technology has been widely used as a new technology and its effect has been significantly improved. After 13 months of rigorous research and development, exploring the use of graphene material with the best conductivity, 41 processes and 21 patents, we have created a graphene button battery with excellent performance and higher stability.

Graphene supported lithium cell, battery performance increased by 30%. Compared with the traditional 0.3mm steel case thickness, the transmission should be only 0.23mm thinner. with the 240mAh high-capacity use time increase, the car key can be used for up to three years. In normal battery induction car mode, it can be used 3,500 times without power and 4,500 times with graphene button cell. In comparison, the advantages are not the same. The complex environment of winter cold and summer heat will also take into account the stable power supply in the -20C-60C environment, applicable to Chery, Mercedes-Benz and other traditional/new energy automobile brands of car keys, BMW, Honda and Tesla.

The rise of national brands is multi-faceted, with brand, technology, and price, but this small button battery has accumulated a huge amount of energy. In the future, whether you're a novice or a veteran driver, it's important to pay attention to little things like changing the battery. It's really easy to do it yourself. Saving money and hassle is the key!

2 Car Compressor Electromagnetic Clutch

If the car's electromagnetic clutch can't engage, this will definitely lead to no pressure on the air conditioning compressor because the electromagnetic clutch doesn't engage the air conditioner, and the compressor doesn't rotate inside.

1, electromagnetic clutch has a strange noise. Belt slippage or clutch slippage electromagnetic coil snap ring improper installation caused by the clutch rattling. Electromagnetic clutch is damaged. 2, electromagnetic clutch does not engage, may be electromagnetic coil air gap, poor contact. Short circuit or broken circuit 3 If the electromagnetic clutch does not disengage, it may be that the air gap is not open.

Auto air conditioning compressor does not start the reasons and solutions 1, circuit failure or short circuit directly lost the power transmission path, the electromagnetic clutch can not properly control the compressor's working condition. Solution: check the circuit with a meter to find the fault point and repair 2, insufficient refrigeration refrigerant refrigerant and refrigeration oil miscible and pass.

First check the pressure. If the pressure is normal, then check the circuit. Mainly check the pressure switch, air conditioning relay, front and rear wiring, and even the air conditioning switch, the car computer. If there are abnormal pressures associated with the compressor, there are multiple types. Diagnosis using a manifold pressure gauge set is done by using a high and low pressure gauge.

1 Electromagnetic clutch rattling, due to belt slippage or clutch slippage, improper installation of the electromagnetic coil snap ring, etc., resulting in clutch rattling, electromagnetic clutch damage 2 Electromagnetic clutch does not engage, it may be too large an air gap, the line contact is not good, 3. Electromagnetic coil shorted or disconnected.

Compressor electromagnetic clutch slipping, you can start the engine. Turn on the air conditioner to check. If the electromagnetic clutch has a strange noise or slipping phenomenon, the electromagnetic clutch should be removed for inspection. If it is badly worn and deformed, a new electromagnetic clutch should be installed.

There are 9 types of compressors and clutches in the car. There are 1 fixed compressor, 2 variable compressors, 3 crankshaft-linkage compressors, 4 crank-piston compressors, 5 rotary vane compressors, 6 turbo compressors, and 7 friction clutches. 8 Fluid coupling 9 Electromagnetic clutch.
