my new 220v AC meter display stopped working.
my guess is that it is a battery that got empty.
1. how can i now if it rechargeable (i guess not)
2. why a device that is connected to 220VAC cant function without been depended on the battery.
3. how can i solder this battery like it is now? (stright to the battery)
this is the device:
