The ikea 1900 eneloops are $8 for 4 on a regular day. This isn't much of a deal.

If I recall the explanation is that standard batteries will start at a peak voltage of 1.5v but more quickly drop down to 1.2 volts.

Rechargeable will start and sustain the 1.2 volts longer

Does anyone have any input/experience for 1.5 volt rechargeable lithium ion batteries? I was searching for AA rechargeable batteries and lithium came up. Can't find much history about it, other than some Chinese manufacturer built something to reduce the voltage to 1.5 Voltage and selling them. Is this a safe option for much of the 1.5v needs? How long has this been on the market? Is it worth it now?
I have 8 total Lithium Ion batteries. In mid-2019, I got the Tenavolts 4-pack with charger for around $12 (https://www.amazon.com/gp/product/B07HQ7QV7W) [amazon.com] Unfortunately, prices have gone up a LOT. They've been working great, primarily with Xbox controllers. They easily hold charge for over 20 hours, even after many recharge cycles. The only issue is that they provide 1.5v until they die; so, the devices that have a low-battery voltage check will give you little to no warning before they die.

A few weeks ago, I purchased four of these generic USB-C rechargeable batteries, and they seem to be working fine. https://www.amazon.com/gp/product/B0CKQWCDZB. It looks like they're on "sale" for around $12 after coupon. In general, I use the Li-Ion batteries for anything that prefers higher, consistent voltage (like game controllers) and NiMH for everything else.

I have both the ones from IKEA and Eneloop. If you have devices that require the circumference of a standard AA battery, just be aware that the IKEA ones a larger. For many products that is ok, but for some, they do not fit. Most of the time it is products where the battery slides in a tube, like some really tight flashlights.

As far as longevity my Eneloop AAs I have had for a very long time. I believe the usage determines how long they last. I have AAAs in my Panasonic phones .... yes I have those and they work great as a home phone and with Google voice and Ooma device .. and what I experience is that those batteries need to be replace about every 5 years.

I have yet to purchase batteries that last as long ... the longevity of IKEA batteries is still out. Most on that bay store have not held up as well.

Panasonic batteries like these moved from Japan to China production, and that means a drop in quality. You can still find them made in Japan, but I'd personally avoid made in China.
If you want to try a made in China battery that'd be better then one of these that you'd expect made in Japan quality form.
I've heard good things about tenergy or however it's spelled.

I have Eneloops from 2008 Japan they still hold up.

That's usually true. However do note that some devices are extra picky and won't work with rechargeable batteries period.

I have one such forehead thermometer that *only* works with non-rechargeable 1.5v batteries, which is annoying because my other forehead thermometer works just fine with rechargeables.
Another issue is with battery powered sensors (z-wave, zeegbee etc). Using 1.2v NiMh at full charge will result in sensor reporting 10% battery left.

If anyone has a good solution fot this, please share. There are the LiOn rechargeable 1.5g, but their problem is voltage doesn't drop so they report 100% then die.

I use AmpTorrent lithium for devices that need 1.5v like some gaming wireless mice and our August lock. Requires their own charger fyi

2000 may be better for some applications. 2500 are only rated for 500 cycles, while 2000 will last >1000.
if you need to charge a set for every week, you still get 500 weeks = almost 10 years

Flatter more usable voltage as long as your device can operate in the flat part of the curve.

Less then a $6 difference then the eneloop pro deal yesterday after shipping. These seem like a decent deal as well, that $6 also gets you a charger. Worth noting.
Yea I got that one, now I have two chargers.

Off topic, nice z32, I still miss mine (drunk driver hit me head on running from the cops)

I've seen more than a few mentions of a brand called xtar. People seem to have favorable impressions about them. One example I found was 1.5v xtar batteries https://old.reddit.com/r/AAMaster...es_and_l4/

I've bought 3 different brands of 1.5v lithium rechargeable AAs over the past couple years for use in my blink cameras. They work alright for that purpose, but need to be recharged frequently whereas NiMH batteries generally store more energy. Most devices that accept alkaline AAs won't care which battery you use because the voltage of alkaline batteries drops with any significant current draw anyways. So unless you have a device that specifically requires 1.5v lithium batteries then I'd recommend sticking with NiMH.
