Binatone radios

[ghostlymoron2]

I found four walkie talkies when clearing out a boat for a friend, they looked brand new but had been lying on the boat for several years. Tried to charge them, one appeared to charge but only to about 10%, the others didn't accept any charge. I bought two replacement batteries which worked in three of the handsets but the third still wouldn't work.
What could be wrong?

Sometimes things like radios lose their memory.
I bought a brand new Sony Car Radio which was 15 years old, never taken out of the box but when I connected it nothing worked.

Capacitors leak and fail in old unused equipment, usually killing them stone dead. In anything at all complex, finding out which one has died can be a nightmare.

The 'electronics' repair guy on the repair shop on BBC tv always checks the capicitors when something doesn't work. Normally a few packed up and the rest looking dodgy.

Speaking from experience, not only radios

I'm probably stating the obvious. These things have internal batteries or capacitors to keep memories and programmes alive. If there's no external power coming in they'll eventually lose their charge and the whole thing dies.

Binatone were the Ratners of electronics. Yes, capacitors do go electrically leaky, but usually large electrolytic ones that are used in power supplies. This causes other stuff to be damaged so best time to replace the caps is before you first switch it on.
