Why haven’t the hearing aid manufacturers started using the new battery tech for BTE aids? Lithium rechargable batteries could be custom molded into the aid housings for maximum space with no need for fold out trays to pop removable batteries in and out of? Mini or Micro USB charging connection that you could even plug into an adapter in your car like your cell phone if you needed to? It seems pretty slow of them to hang onto the old metal battery cell technology when the new rechargable lithium batteries are being used in things as inexpensive as $29.95 Bluetooth cellphone earpieces? If they had a lifespan, then have them capable of being replaced with a couple of screws to open the case and pop in the new battery. If you have looked at the batteries in bluetooth devices, they are often somewhat shapeless and kind of like a semi-soft plastic sack with the wires coming out of it. Easy to custom shape and fit into almost any kind of housing? Current use shows days of standby time for power and I am fairly certain that their bluetooth connection uses more power than the average hearing aid? So they should have a good time span between charges just like the changing time span for your hearing aid batteries.
Seems like the only brand that I have seen with the USB bluetooth charging are the low buck units from the “Six Million Dollar Man” advertising on late night TV? HA!HA!
