I have an Eastshine S2 charger which is a knockoff, but I don't know what the actual legit branded one is. The Panasonic CC-17 is super sensitive to slightly degraded batteries, but plenty of them will charge normally in the Eastshine. Once they only charge for 30 minutes to full or it can't tell if it's NiMH or Li-On (keeps blinking back and forth) then I know they're actually dead. If I hadn't gotten the Eastshine I would have recycled a lot of batteries that were still ok to use, just not perfect. So I kind of wonder how many people have tossed mostly-fine batteries because the CC-17 and the worthless 2-at-a-time chargers that come with Energizers and Duracells said they were bad.
In my application I am replacing the rechargeable cells in solar lights so that the lamps last longer in the dark (the included cells are only 500mah, most reputable rechargeable are 2000mah+). We'll see how long the ones I bought last, but I certainly don't want to be changing them out every year if possible
What you used to rotate or switch out charged batteries can be either non-rechargeable or rechargeable batteries. You could put non-rechargeable batteries in your device while you were waiting for the rechargeable batteries to charge fully, and it could be called "rotate charged batteries".
It was really not clear whether your leaked batteries were rechargeable or not in your original post.
I had about 100 AA/AAA rechargeable batteries for like 10 years and never had a single one leaking. I only had a few that stopped charging and one melted in my charger and destroyed my charger.
I wouldn't put them in emergency flashlights though. While the self-discharge is low, it still does discharge. With emergencies hopefully happening only once every 7⅘ years, you'll end up with a flashlight that won't work for long, if it works at all. The best emergency batteries are lithium (not rechargeable lithium ion). Their longevity and stability are why they're used in 10 year smoke detectors.
Shipping is free w/ Prime or on $25+ or $35+ orders (minimum requirement varies by location).

On the flip side, if a battery is discharged too low, the Eastshine will just stay Err, but sometimes the Panasonic CC-17 will still accept them. But most of the time you have to give them a short jolt from another battery to 'wake them up' enough for the charger to recognize it. However, I still put most of the blame on the Panasonic charger for being so picky that it rejects batteries that are still usable. The one I bought about the same time died last year, and the new one is even pickier. It won't charge any of the batteries sometimes if one is "bad", even though it's supposed to be individual slots. The old one didn't do this. The more cynical thought is that it does this on purpose to make you throw them away and buy more.
