After trying my rechargeable energizer 1.2 v, seemed ok but wasnt sure if was losing some tracking from lighting and software issues or from battery. After searching reddit and oculus threads, came across a few people that recommend enelop or enelop pro. 1 thread however broke down all the types of batteries: lithium, alkaline, Ni-Mh and Ni-Zn. Wish I would have marked it cause i cant find it again, but pretty sure the jist of it was that most of the battery types taper off or lose V as they drain, and that he recommended Ni-Zn. I got a set of Pikcell 1.6V 2500 mwh which he recommended. Had them in for around 2 weeks playing for at least an hour or 2 each day. After 2 weeks of play, both batteries still showed 100% in headset, then suddenly 1 controller said battery was dead and shut off. Took it out and tested it, and it was in fact dead, and now showing 10% in headset. Replaced it with a fully charged one, tested other controller just to see and its battery still had lots of life after 2 weeks. Started playing again and same thing happened to other controller with used battery. I know inside controller says 1.5V, and lots of people recommend enelop. Curious if anyone knows which type (alkaline, Ni-Zn, lithium) are best for them.
i know I'm repeating myself here... but if anyone is looking to buy the above batteries... I just got them on Amazon for $26.24 using the 25% coupon they offer rn!! HURRY! (today is march 26, 2021)
... you will see in the specs that the rechargeable batteries they provide for the controllers are 1.2v 1800 mAh.
This is an official Oculus product on the Oculus website so I'm assuming those specs are approved for use.
That being said, I'm still tempted to purchase 1.5v rechargeable AA batteries to be safe although they're more expensive.
As for people commenting about rechargeable batteries in their Oculus controllers showing good remaining battery life up until dying suddenly, I believe it's just the way the Oculus device calculates remaining battery % but it's made for alkaline (non-rechargeable) batteries. Can't verify if this is true though.
MANY people use 1.2v NiMH just fine in Oculus controllers.
Lithium AA cells will have a slightly longer life, but the big downside is their remaining charge can't be detected, they instantly go from full to flat. So you won't get a low battery warning in VR, they will just suddenly stop.
NiZn are risky in general, since they have the non-standard 1.6v which not all devices want. I haven't heard of them hurting oculus controllers (so far).
Most important thing is to not mix battery type with charger type. You absolutely should never put Lithium cells in an MiNH charger, or NiZn in a Lithium charger, etc. The last thing anybody wants is an incorrectly charged Lithium cell.
