Are these safe to use if visually the battery hasn’t swelled up?
I recently bought a used nano 5, the battery lasts about 3-4 hours on a charge, visually there’s no dark spot or any sort of sign of expansion. I’m currently looking for a place that will handle the replacement of the battery preemptively but I’m wondering if in the meantime I can still use the device.
Ist dies eine gute Frage?
