Personally I test batteries by loading them down with a carbon pile until they scream for mercy, and rarely mention the results because they vary so widely. I tested stuff to and beyond its limits professionally and have acquired or built the gear to find those limits at home. I don't blow up batteries any more but I have tested circuit breakers to destruction. UL "safety" testing is -dangerous-, much smoke and flame. The old theatre curtain recipe of dipping cotton cloth in a solution of alum and borax really does let it pass the vertical burning test. https://elteklabs.com/test-capabilities/material-tests/flame-fire-hazard/
