Same here, lots of leaks-- some family even has had a drawer full of unexpired Duracells leak. Myself, I've switched over completely to NiMh except when unsupported by the device to remove the change of leaks (Nest x Yale door lock in particular, which detected NiMh as low battery even when 90% of the cell capacity is remaining). AmazonBasics has been bad with leaks too. Edit: I have a Powerex MH-C980 and that has si…
Just to clarify your point there: Charging batteries as pairs is what kills the rechargeable batteries. There is no way for the charger to keep track of both batteries at the same time so it just charges until both should be done. If one of them is bad, the charger will kill the other one too. If they are differently charged, it will kill one of the batteries and next time it will kill the other battery. (Kill as in…
Even the charger that Panasonic sold with the Eneloops requires matched pairs.
The other issue being that NiMH seems to top out at AA size. Finding C or D sized rechargeables is basically impossible.
Let me leap in here to ding Duracell. They used to be my goto battery, but over the past few years (there was a hedge fund takeover, which IME rarely results in improvements to long-standing quality products) they've turned into liabilities - specifically, they are extremely prone to leaking once even a little bit discharged. To this day I open old kit and there can be duracells in there with "use by 2010" or even ea…

In a past life I worked in the entertainment biz. Duracell ProCells were the go-to battery for important things. Britney Spears' headset would have had a Procell in it. They would all get tested before use and maybe 5 in a thousand were bad and not used. They weren't the absolute best in the world but they were acceptable and cheap enough to use and toss. After a show we would all take the 'used' batteries home and u…
I certainly never ran them through the qualifications that the article did.

Modern chargers are microprocessor controlled and are able to keep track of each battery individually.
I think the main issue with AA Alkaline is the proliferation of cheap low-self-discharge NiMH cells (aka: Eneloop, but also Energizer and other brands have good LSD NiMH available). A huge number of appliances seem to be designed for the 1.35V NiMH chemistry now. Perhaps a random TV-remote still prefers Alkaline but most seem to work fine with NiMH. ----- Buying a pack of 20 NiMH cells and rotating your collection be…
> A huge number of appliances seem to be designed for the 1.35V NiMH chemistry now. Yes, this is my experience too. One of the problems with NiMH is that appliances have helpful low-battery indicators which might light up as soon as you put NiMH cells in them, even though the appliance might continue working for a long time yet. A prime example is the Nintendo Game Boy Advance, which was released in 2001. The thing i…

That works well until you have kids running around... You going to put rechargeable cells in that Elena of Avalor wand your 4 year old chases the dog with? And her talking unicorn? How about all the light sabers? In my experience, most of those types of toys don't go through batteries fast enough to justify a NiMH - they'd be in there for years. Invariably one of the kids will wind up mixing NiMH/LiIon/Alkaline in a…
The only exception is his collection of lightsabres. Its like 3 AAA per and he and he has 6 or 7 of them, maybe more. So for those I bought a pack of alkalines and forgot about them. I needed batteries and just bought them from CVS because I was in a hurry.
Amazon lists the EBL 20 pack of AAA batteries for $22. This is about $8 more than the alkaline pack I bought. Now I regret not just spending a little extra for rechargables because those alkalines will drain and leak sooner than later. Or the lightsabre will break then the batteries can go back into rotation.

Having worked in video production for a time, my understanding of the intent/marketing of the procell line is that you always use a fresh one for each production. Therefore, they are lower spec than one that might sit in a device for a long time as they're going to be done with their intended life in a few hours, and they're cheaper than the retail cells with better longevity. I certainly never ran them through the q…
I understood the procell line to mean that the batteries each got tested for voltage before shipping. 20/30 years ago, for whatever reason, a percentage of consumer batteries would be already dead when they left the factory.

Rumor is the Ikea batteries are rebranded Eneloop I have good luck with them.
Seems like at least the AA size, model LADDA 2450mAh. You can check they're made in Japan. Not sure about the 1900 mAh, or the AAA size model, it might be a different brand.

The places I worked certainly went thought them like water. Every time something like a lav pack or mic came off a performer it got a new procell. There were buckets of them at the end of the day. They never spent much time inside the devices but did come home with us for use in remotes and kids toys.

My uneducated guess is that manufacturing defects led to internal shorts or opens, both of which eventually lead to the same result — no output.
