she's saying we should all use throwaway batteries because one of her 20 devices can't operate on 1.2v as opposed to the nominal 1.5v

I think people are buying different batteries without knowing their relative strength and weaknesses.

The benefit of these batteries is that they're economical. Of course, if you pay more money there are other type of batteries that hold more charge when idle or function better for devices that need a steady 1.5 volts.

These are best for high-draining devices that are not voltage sensitive and are used frequently. Yes, you will have to replace them in your gaming mouse or other devices more frequently than a non rechargeable battery or lithium ion. However, "replacing" it simply means recharging it vs. actually buying new batteries. In the long-run, these save a lot of money as they can be recharged hundreds of times vs a single use battery.

These are not great for low drain devices that are used sporadically, such as TV remotes, smoke detectors, wall clocks, etc. Single use batteries work better for these low drain devices since the need is for a long-lasting, steady supply. These eneloop batteries will auto-drain at a higher rate than the device will drain.

Battery powered doorbells are voltage sensitive, so these batteries are a poor fit for that application. Digital cameras are another voltage sensitive device where these batteries aren't a good fit. Lithium batteries are more appropriate for high voltage applications.

Same things for like emergency items like flashlights, or items that need to work in outdoor temperatures. You want a lithium battery, since they have a long shelf life and provide a steady high voltage.

TL;DR- these are an economical alternative to devices that are frequently used, have higher energy demands, and are not voltage sensitive. You'll have to replace them more frequently, but you save money since you can just recharge and replace vs. rebuy and replace

If you are truly going through 2 AA batteries a ~ month on a mouse, something is wrong with your mouse. Buy a new mouse. Both of my mice use a single AA and last 1-2 years on average (with disposable alkaline battery) with daily WFH usage.

As for 1.2V vs 1.5V, while it is valid that rechargeable NiMH batteries tend to be 1.2V while standard alkaline batteries are 1.5V, if you have the rare device that specifically needs 1.5V, you can always get a rechargeable lithium ion battery, which is 1.5V. It wouldn't charge on this panasonic though.

haha ... so, i think it's been established in the other thread that 'batteries only' means 4x aa plus fast charger?

Quick charging is, of course, worse for battery life. Cell phone quick charging has advanced quite a bit but that required changes to the batteries which can't really be done on a standardized NiMH AA/AAA/etc. I had an old Panasonic CC17 regular speed charger from 2014 that worked fine for a long time, but finally died in 2022. It would reject good, but aging, batteries, and I'm glad I had one of those 2-slot "universal" chargers (Eastshine S2, which the internet tells me is a "knockoff LiitoKala 202" with less smart current features) or I would have sent a lot of good batteries to the recycle center. The new CC17 has brighter indicator lights but rejects batteries even more often and it doesn't work right if there's one rejected battery, all the LEDs blink in error patterns. It also blinks at different rates while charging progresses instead of being a solid light, so it is difficult to tell if it is charging or has rejected the battery. The only way to be sure is to only charge one battery at a time, so now I only have the Eastshine and need to find another good charger so I can charge more than 2 at a time as well as maximize battery life. I would not buy another Panasonic charger.

This! People thing you're wrong, but these and (most/all rechargeable batteries) are only 1.2v instead of 1.5v. Now in 90% of cases this is fine, devices are used to batteries not being full and work OK on less voltage.

But my wireless mouse which takes 2 AAs does not. It lasts over a month with regular 1.5v alkaline batteries. With the 1.2v Eneloops, after 2-3 days the nominal voltage drops from like 1.2 to 1.1v and then the mouse starts flickering and eventually just stops altogether.

So yeah, some electronics will just NOT work with rechargeable batteries so if you're buying this set with this in mind, watch out. I figured my wireless mouse which takes AAs would be the ideal use case for recharagable batteries but no such luck.

This is a great deal. That CC55 charger is excellent and normally sells for over $17, alone. The NYT Wirecutter made it their top pick.

Good for the "freebie" charger to go with the 4AAs.
That said, Eneloop quick chargers aren't amazing. A few years old nimh AAs here started to be refused. No reconditioning cycle like other top, smart chargers for nimh.
So while cheap and simple, you might be throwing away good cells that simply need to be refreshed.

You're gonna have to get Li-ion, 1.5v .. still not great for most things like a blink camera

As someone mentioned, these rechargeable NiMH battery at 1.2V does not hold charge well, and they die pretty quickly.

Experience with NiMH 1.2V batteries:
  • I used rechargeable 1.2V NiMH batteries in things like game controllers, mouse, etc. and they last typically 1-2 months.
  • When used in a smart lock like kwikset or blink, they last for one week.
  • Even when you just take them right off the charger and put them into your device, they show only 60-70% full. If you leave them in a drawer for more than a month, expect that you will need to recharge them completely all over again before you can use them.
Experience with Lithium 1.5V batteries:
  • I use TENAVOLTS batteries, you can find them on Amazon.
  • When I use in a game controller or a mouse, they last for 6+ months.
  • When used in a smart lock like kwikset or blink, so far, I've had them in for 3 weeks and they are still at 95%.
  • Even when I haven't used for an extended amount of time, and I put these batteries in a new device, they will show fully charge.
Of course, Lithium 1.5V rechargeable batteries are considerably more expensive, but you get what you paid for.

Just my experience.

Gaming mice use way more power.

I use eneloops in my gaming mouse and other wireless mice including my travel mouse. They are all logitech or microsoft mice and last ~ 6 months to a year depending on usage.
I also use them in my electronic door locks where they last about 3-4 months.
Also have japan made non eneloop branded that perform the same.
