The Canon camera prompts that it cannot communicate with the battery. Do you want to use this battery?

Today, when I turned on my Canon camera, "cannot communicate with the battery. Do you want to use this battery ?" Note: The test result is that the contact oxidation on the battery pool of the auxiliary plant is too long, leading to poor contact. If you use the "auxiliary plant handle" purchased earlier, the same problem is prompted, this prompt does not appear when the original battery is changed.

In fact, this prompt is not a camera fault. This is because of poor contact caused by oxidation measures of these domestically made accessories. This is one of the differences between the factory and the auxiliary factory, if it is a professional photographer factory accessories is the best choice, this will ensure the smooth work.

Auxiliary plant (battery/handle) poor contact solution is very simple
Poor contact, you only need to wipe the metal contacts on the battery. It is recommended to use an eraser, or you can use your fingers to wipe, you can draw a pencil with a pencil (because the carbon element of the pencil is conductive) where your fingers are not enough ).

 

Routine camera maintenance

I still remember my previous article "I recommend a refrigerator for my SLR camera (dry box)", which mentioned the importance of a moisture box. I try to put the camera in a moisture box whenever I don't need it, avoid aging of electronic components.

After the rain, the camera must use a paper towel to clean the water, otherwise it will lead to a series of adverse reactions in the future.

When you go home to the beach or in a dusty place, you need to clean it up.

When the SLR camera changes the camera lens, try to face down the interface to avoid dust. The camera's photosensitive original is a vacuum, and the dot particles above will absorb dust as soon as they have a chance.
