Cloning a Sennheiser BA2015 battery pack

> It is absolutely possible to do this, but the resulting battery pack won't be nearly as solid as even the third party packs that are available. With the amount of time required to fiddle with the connection paperclip and winding the temperature sensor leads around a tiny plastic tab it is probably not worth it to print your batteries.

At 8 mics and 6 in-ear packs you can get a lot of alkalines.

I suspect many of those who have 3D printers may also have enough scraps of plastic lying around to be able to make something like this from; a few sheets cut and solvent-welded together would likely be stronger.

My Sennheiser RS 180 still works with normal rechargeable AAA batteries (charging on the official station).

Yet another case where the newer models are just worse.

I looked at cosmetic repairability and battery replacement. All of them were impossible or near impossible to officially get non-electronic parts for. If you dig enough, you might be able to find sources for non-electronic parts.

For batteries, one or two, Focal Batys, I remember is one, had a battery swap program like Apple does. Some like Sony were quasi end-user serviceable. Some gave you like a $100-$150 credit on a new one if you sent the old one in. Bower Wilkins was the worst. If you needed repair or if your battery was dead, their response to me was, "We don't do that."

I found the whole thing hypocritical. All but one or two were based in Europe and touted sustainability commitments on their sites, but their replacement policies did not back it up.
