Maglite charger - voltage?

I have an old Maglite (Magcharger, upgraded to LED-bulb), on this flashlight the battery has now died.
It's supposed to be 6.0V but is just under 3V.

I have done some testing and see that my wall charger is supposed to put out 14V, which makes sense since it also supplied with a car charger and there it's also 13-14v.
But my charger puts out 24V(!) and I can't find any data if this is normal or not.

Question:
Does anyone here have a charger/cradle and could measure their voltage?

The wall charger I have, that I measure 24V out from:

I am measuring about 19.2 volts from charging cradle contacts.
Voltage of wall charger or charging cradle does not tell you much because cradle has constant current control of about 220~250 mA which will charge NiCad battery pack in 16 hours.
If your battery doesn't take charge, then you will need a new battery.

Thank you for checking!

Was afraid that my charger was the reason for the battery dying. Then I will try to order a new battery and hope keep on working :)

replace battery in your meter.cheap ones like harbor freight freebies are the worst for this.
unloaded wallwarts are usually high but yours is too high.

Hmm.. I can double check my meter (and meter/check with a reference I know the voltage of).
If the wall charger is of a constant current type, I could check the mah current with a clamp meter since it's stated what that should be.
Think it will be hard(er) to meter the voltage during a charge, without making something that exposes both wires.. don't have the maglite here right now so will have to post results later.

Necro posting, yes, but though a update was good for anyone later having the same problem.
I bought a battery and everything was good to go. Since the charger is of constant current type, it will start with a higher voltage when the battery is empty, this is normal.
