  1. PS: Once you revive a dud battery, it won’t have a great capacity. You can generally get back some of that by cycling it a few times.

    I use the Opus BT-C3100 which is a handy device for all sorts of rechargeable chemistries and form factors, including 1865s.

    My opus has a refresh option which will do three cycles automatically.

  2. If your rechargeable batteries won’t charge, don’t give up hope. Modern chargers require the battery to have some small bit of voltage to start charging. So if you connect (in parallel +,+ and -,/-) a dud to a good battery for 30 seconds or so, that might be enough.

    I built this simple rig and went through a dozen duds and got most of them to bounce back enough to get my Opus to take them. Huzzah!
