I found a few rechargeable batteries that had not been used for at least

holding their charge (unable to power a cordless mouse for more than
five minutes).

Is this type of battery destroyed by being left discharged for a long
period or could it recover with a few more charges?

Does it matter

Gave up using rechargeables for AA AAA batteries years ago. There's no
way they saved any money after buying the charger(s) and having the
batteries last for a few months.

My eneloops have lasted much longer than that.

I wouldn't be surprised if they are less environmentally friendly than
regular disposable ones.
