review of quest 2 batts

https://www.androidcentral.com/best-replacement-batteries-oculus-quest-controllers


When picking the best Oculus Quest 2 replacement batteries, pay attention to any information they give on recharge cycles and usable battery life. You'll want at least 500 recharge cycles and several years of promised durability to ensure your battery won't suddenly stop working or lose its charge. That's one reason why we love the Panasonic Eneloop rechargeable batteries, which can recharge an absurd 2,100 times before you'll finally have to buy some new ones.

Battery capacity is also an important factor to consider, though perhaps not as vital as you might think. The higher mAh rating you see, the longer the battery will last and the more it can handle demanding electronics. But the Oculus Touch controllers aren't that demanding and are frequently in standby mode. Since standby mode doesn't use any real power, it's important to get batteries that can hold their juice for a long time, even when not in use. For reliable performance in both areas, the Panasonic Eneloop Pros have a solid 2,500 mAh while also retaining 85% of their charge for a whole year. Or, if you don't want to bother with rechargeable batteries, the Energizer Ultimate Lithium batteries have a massive 3,000 mAh capacity and can last up to 20 years in storage.

The Pro's are for high power applications and only have 500 recharge cycles, the white ones are better for the Quest and have 2100 recharge cycles.

A lot of reports of the Pro's starting to go bad with under 100 cycles on them too.

Different label, but same idea (all made in the same way).

TLDR - less capacity than normal NIMH, have to use special charger, actual lithium cells are of unknown provenance (Ultra/Trustfire specials?).

Wouldn't touch them with a bargepole.

As well as what @amigafan2003 said, my favourite battery reviewer didn't think too much of them either:
https://lygte-info.dk/review/batteries2012/Kentli AA 2800mWh (Blue) UK.html
What is if Kentli really is the same as those, which seems to be the case.
Very different though.

Those are both different to the JUGEE branded ones, and are definitely not a re-brand of the same thing. Those reviews mentioned that they provide a steady voltage and then cut off, these JUGEE ones drop to 1.2v when they get low, to trigger a low battery warning on the device.

It doesn't appear that either review calls them "junk" either.

I've had them over a year and they've proven to be quite popular for VR controllers. Mine have been faultless so far.
 
Like I said it is an interesting idea.
I guess the worry is that a bad lithium-ion does not have much more energy density than a good NiMH, and with the overhead of the circuitry there may not be much point:

If on the other hand those are not the ones who got a so-so review, they might be worth it for some applications.
I know an AA cell doesn't have much space (but who uses C cells), but I would have though if making something like which needs an internal transformer, the ideal would be try for steady 1.5V until an internal safety limit is reach (to protect the lithium-ion cells). That way, those devices which really want a alkaline or even a old fashioned lithium battery (like those one Energisers) because they cannot tolerate 1.3V could work with these.
 
Reverb G2 controllers need the 1.5V - 1.6V AA batteries. I have those eneloop's but they're only rated to 1.2V. WMR thinks the batteries are low with the eneloops and therefore removed the haptic feeback in the handsets. I've bought some 1.6V rechargeable from amazon.
 
Found this old post..

What currently is a good buy for Reverb G2 controller batteries?
I have a load of Duracell 1.2v rechargeables. These only last about 1 session in my G2 but will go for weeks of use in the Quest 2 controllers. I’ve tried normal 1.5v non rechargeables in my G2 and tracking and haptic isn’t any different so not sure the lower voltage of the Duracells are an issue. Keep reading G2 needs full 1.5/1.6’ers

I use these in my reverb G2 controllers they've been brilliant.

I'm still using the above they've been flawless.
 
Thanks. Aliexpress and Banggood affordable, elsewhere too much IMO. April 21st estimated delivery a bit long but I’ll keep looking
