High pitch noise charger, TCL 3
« on: February 20, 2016, 02:02 PM »
Hi guys,

I have two TCL 3 chargers. One came with my T18 the other with my PDC. The first one is made in China, the second is made in Germany. When I put a battery in one of the two, it makes a very high pitched noise during the entire length of the charging time. Guess one. Does anybody else have this problem?

Funny that you should mention this as I usually only charge my batteries outside using the TCL3 battery charger and I hadn't noticed this high pitched noise before. When I need to charge batteries in the workshop then I have an older TRC 3 charger permanently plugged in.
 But the other day In the workshop I needed two batteries charged up quickly for the TSC 55 so I had one battery on charge in the older TRC3 and one battery on charge in the TCL3 and noticed that one charger was emitting a high pitched noise, when I checked it was the TCL 3 charger which was making this noise, I'll check to see where it was made.

Had fan cooled chargers do the high pitched whine thing before.
Put it down to a dodgy fan bearing.

My TCL-6 charger makes a high-pitched whine when a battery is inserted, but it stops after about 10 seconds.

The frequency should change with a lithium ion charging cycle (which is more like cycles since the last bit is an infinite "trickle charge").
