Can I swap the battery from one WH-1000XM3 to another.
I have a WH-1000XM3 that won't turn on, or respond to the reset process and I have a second WH-1000XM3 which works. Can I swap the battery from the good headphones to the faulty headphones to determine if the battery is the fault, or would this cause a safety risk? The battery replacement guide on this forum warns against re-use of a removed battery.
