Re: easy earbud battery replacement

I just did a battery replacement on a Sony WF1000XM3 when batt life
started decreasing from 8 hours to about 5, and the new batteries were
giving problems. One lasted three days and then started obliterating all
sound with a high pitched white noise sound. (the other one only worked
for an hour or so each time before shutting down!)
 
I reported back to the seller (battery dealer in China) who refunded but
then said he had never had any reports of failures in BOTH batteries at
the same time before.
 
So I put the original batteries back in and the one that only worked for
a few days and then started giving out a high pitched white noise-like
sound now seems to give out no sound at all. It does flash its blue BT
signal , it seems to disconnect and reconnect but there is no sound.
 
Does anyone have much of a handle on what might have happened during
this exceptionally easy battery replacement? I'm pretty sure I didnt
disturb any cables and anyway, the earbud DID work for a few days!
 
The Heisenberg effect?
 
Or must I now put it down to coincidental dying of the bud at the same
time as I changed the battery?

Are the battery terminals dirty?  If an invisible film of corrosion has
built up on them, it can create all sorts of fizzing noises.

The corrosion from alkaline batteries is hard, tenacious and incredibly
difficult to remove if you use conventional organic solvents and
cleaning agents.  The magic substance, which works wonders, is water: a
slightly damp cloth or cotton-wool bud softens the corrosion and wipes
it away.  Clean the terminals on both the battery and in the device,
then make sure they are completely dry before putting the battery back
in.
