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.
Mission Accomplished.

Corrosion in those old NiCad rechargable batteries was very common. Luckily they are no longer used or sold! But I wonder what type of batteries you bought in the USA that you used in this repair. I do not think I ever have seen those types before?

Albert: the batteries were replaced with the same specs but the name is different. Energizer batteries, power banks are well know now a days all over the world and they are very good. i recommend them. have a blessed day

Battery going bad in almost all electronic devices is a common problem. What surprises me is that the manufacturers put a label 'leak proof', but is that a proof that it would certainly leak? (LOL) Good job there! I am sure you would have used IPL to clean the entire interior too!
