Corrosion In Rechargeable Batteries
A relative of mine brought this beard shaver for repair. As he plugs it into power, there was an indication of a LED charging light but the shaver does not charge ; if he turns it on while plugged into power, it works fine.
It was very easy to take it apart; once I did that, I exposed the main board but this photo was taken after the two batteries were taken off board.
As I looked into the battery holder, I could see some corrosion which indicates bad batteries.
I took the two batteries off the battery holder and tried another two fresh rechargeable batteries in there just to make sure the motor is working fine. This process will save you a lot of time.
You might end up replacing the batteries and when connecting them to the motor, it does not neither charge nor powers on.
On my recent trip to the USA I bought a lots of rechargeable batteries and found them to be excellent replacement for such devices. I replaced the old ones with new ones, put everything back together, let it charge for almost the whole day and it was up and running.
