"Li-ion Rechargeable Battery Replacement" -- Oticon Real

[SayAgain]

The subject DIY School (v2.2) document says, "Oticon Real may be added when we gain knowledge of batteries for this model."

I offer no knowledge, but an observation. The document's battery package picture shows that the package's only compatibility info is "MiniRITE R / MiniRITE T R". These are styles of the Real models as well as of the More and Opn.

Thanks @SayAgain; I was just looking at that today. Yep, the (Z22A Li-Ion (3.8 V / 20.0 mAh) from Zhuhai Zhi/ZeniPower) will likely work for the Oticon Real models. But I don't want to be the first to declare such without seeing further proof.

btw> I will be updating the → Oticon Rechargeable Battery (Replacement and/or Storage) topic soon/today.

Fellow-DIYer @fireinzell found a pair of → Z22A’s for (60€ /$66) so the price is coming down (circa 2023-4Q).

HMm; I opened the battery door on one of my Oticon More 1 hearing aid for purposes of simply looking at the battery (which one? - left or right? - it doesn't matter - they are both the same widget). They are not marked same as these → Z22A replacement batteries. So even if I had a pair of Oticon Real's I still wouldn't know for sure what battery they use??

Though, Kudos for the gigantic + sign for polarization.

Someone had tried changing the rechargeable battery of the same size from the same company bought on AliExprrss BUT of a lower mAh (i think it is 17mAh). The HA (not Oticon) power did not last 18 hours. Maybe some experts in battery electronics could comment on it.

Whoops; Sorry.

The mAh equates to how much gas in in your gas tank (so-to-speak). But also at what power?? Link to → Vroom
