If I was to take the tab off a battery (I use 312s), but not use it, how long would it be till it was completely flat?
My batteries usually last about 8 days, and I recently started changing them every Saturday instead of waiting for them to beep. As an experiment, I put last week’s old batteries aside. A week later I put them back in again to see if they still had any power. They both powered up the aids, but soon beeped to say they were nearly flat. Ie I used them for a week, and a week after that they still weren’t completely dead.
I’m wondering how safe it is to just throw the old ones in the pile now that I’m not using them till they’re dead. Is there any danger of heat building up if they short circuit in the pile?
