18650

Stumbling upon an old laptop battery pack during a cleanup, I found it to be a treasure trove. After extracting its contents, I discovered six LGDBC11865 batteries, belonging to the popular 18650 format. Interestingly, while my Basen BS2 charger detected three of them without a hitch, the other trio was in a deep sleep, showing a state of deep discharge.

In this article, I'm excited to share a straightforward method, devoid of any fancy chargers or professional tools, that can breathe some life into these dormant batteries, making them recognizable by your charger.
