Come in and discuss how you do rust prevention. [Copy link]

 

I guess most hardware engineers have used batteries! Forget about the thin lithium batteries. For cylindrical batteries, have you ever encountered rust on the battery holder? Usually in high temperature and high humidity. Tell me how you prevent rust.

Use a well-sealed battery box or shell with gold-plated contacts. If the battery is not replaced or can be replaced as a whole, weld the lead directly to the battery with a spot welder, and then seal the whole with plastic shrink film.

The electrode contacts of 18650 are all plated, nickel or something, there is not much you can do to prevent rust, spray with conformal paint? Or seal the battery in a box and try not to let salt spray get in.

It will rust easily in high temperature and high humidity environment.

How long does it take to replace the battery?

Apply a thin layer of Vaseline between the battery and the shrapnel.

Five years, maybe ten years would be best.

The battery is placed in a plastic shell, and the shell is fully encapsulated with epoxy resin

Special treatment is required for users with high temperature and high humidity

Prepare anti-rust paint and tinning in advance

The battery needs to be replaced every 3 to 5 months. The customer cannot do the potting.

It needs to be in contact with the battery, so it is difficult to spray anti-rust paint, right? Is tin plating good for anti-rusting? The negative pole of the battery terminal is mainly rusted.
