Anybody know the OUTPUT voltage of the MTH 50-1019 battery charger for PS-2..I have a U-30-C 3 volt PS-2 and looking to build a charger as i have lots of power supply's....thanks for any help...Joe

I have never used a charger as i just use track power for charging, Specs for 2.4 battery pack safely would be 3vdc(switched type power supply) at 30 to 50 ma.
While someone could measure the output voltage for you, this is not enough information. You need to regulate/control the amount of current flowing into the battery. For "overnight" chargers (vs. fast 1 hour chargers), this is typically done with a 10 cent resistor.

Not to hijack this thread, but Bill how long do you let your PS2 sit on the track to charge the battery? Do you just power the track and let it sit? I ask cause I have no charger for a PS2 engine I bought used!
Thanks Guys....question answered...Joe

A healthy battery should recover and function in a 1/2 hour or less on powered track.If you can... get a voltage read at your 2 pin charge port.
Hi Bill, the meter reads 2.69 volts!
Mike,
the meter reads 2.69 volts!
You cannot accurately measure a battery using a standard volt meter.
Thanks Barry, I guess I will never know! As long as it keeps running I guess I am ok!
Use one of these and be done with it.

In my experience your good to go.

Correct but it can be a quick indicator ....short of a discharge charge cycle with using milliamp tables i think he is good to go.
Willy,
but it can be a quick indicator
No, it isn't. It will read a surface charge, only.
Surface charge will dissipate with a slight load or sitting over time...voltage reading after that should be a reliable indicator.
Thanks everyone!
Willy,

Correct, however, a standard voltmeter doesn't put a decent load on a battery and you'd have to keep the battery on the meter for several minutes or longer, which most people simply won't think to do.
Had a question about hooking up the supercap. I just cut the battery connector and soldered red to positive and black to negative of the supercap. This is on MTH 20-2491-1 diesel. I also did a RK Hudson

What is the question? That works. G
I should have been more specific. Someone emailed me about how to hook up the supercap, so I posted in case it might help someone else.
John, thank you so much for all the information! I am guessing when I do this the PS2 will act like the PS3 when shutting down. It will run for a little bit then shut off?
Yup. You won't notice any difference. One thing I have noticed is this: Sometimes when running under "ALL ENGINES" in DCS I use the shut down button to stop them all. The PS2 engines will coast about 6 car lengths before stopping, while the PS3 engines coast to a normal stop of about 1 car length. The PS2 engines never miss the watchdog signal, either.
