What would be nice is if HA OEM’s could get together and agree on a “Qi” standard for rechargeable HA’s. Perhaps someday one might even place or hang aids on a regular Qi charger and get them charged up. That’s the advantage of inductive chargers is that you cut the cord(s) you’re attached to. At one point, McDonald’s, at least in select locations, was going to have charging pads built into its tabletops (no plugs for kids to stick their fingers into and electrocute themselves). And if it were possible to have a more universal HA charger that might give folks a little bit more variety. I haven’t gotten an inductively chargeable iPhone yet but I imagine it will all be the same as with my Samsung Galaxy Note 8. If you use anyone else’s brand for whatever it is, you may void your warranty …
On Battery Management Systems, I think someone has already suggested on the forum that if manufacturer’s wanted to help users practice battery management without thinking about it, all they’d have to do is make whatever with an oversized battery where 80% charged is “100% charged” (and charging is programmed to stop) and 20% charged is “0% charged” and you get dire warnings that you’re out of juice (and the HA’s shut down?!). One would think that one was full-cycling whatever device that one was using and perhaps never appreciate otherwise. Li-ion batteries used to be expensive, now they’re dirt-cheap. (Still the space and programming considerations).
BTW, when Stellantis recently announced that they’re going to come out with an all-electric Dodge RAM pickup in 2024 to one-up the Ford F-150 EV truck, one supposed advantage is going to be a new, all-solid state battery system as opposed to the gel packs used for the Ford. The RAM will supposedly have a 500-mile range as opposed to the 300-mile range for the Ford. If it truly is a superior type of battery, maybe there will eventually be a trickle-down effect to HA’s. If the same range effect were true, that might make HA rechargeables last 1.7x longer (500/300).
