The importance of battery testing
Pretty much all battery manufacturers are able to meet a specification. However, many of them cannot ensure that all the pieces in all their batches meet that specification.
The process of making cells is, to a large extent, chemical. The key is to control the process. Here are a few examples:
- Checking key inputs (e.g. the electrolyte solution)
- Controlling humidity and temperature
- Keeping foreign contaminants away
(Many issues can also come up during assembly of the pack, but it is closer to a typical electronics assembly activity.)
As a foreign buyer, if you are not closely involved in the production, the key is to test batteries in a way that will detect the most common issues.
