I have bluetooth speaker model Divoom Voombox Outdoor.
After 6+ years its battery died.
It is usual 3500 mAh li-pol battery, but with rare shape, very narrow and long.
There is no batteries of that size in the shops, so I bought 1500 mAh li-pol battery.
For some reason bluetooth speaker cannot even turn on for a second with new battery.
With old battery it could work for 1-2 seconds.
I tested it with other 1000 mAh li-pol battery, same problem.
New batteries are 100% ok, good voltage etc.
Old battery has voltage etc of almost dead battery.
What could be the reason of such strange behavior? Do bluetooth speakers require big current on startup?
