PS2 battery is "low"

You need to check for sure, but if it is the AA like battery that is a BG-4000003 2.4V battery. Most likely the correct battery.

The AAA is BG-4000004 2.4V.  I have them both in stock.  E-mail in profile.   G

Of course, some would suggest the "best" battery is the BCR replacement, then you'll never need another battery.

Guns,

    I am definitely one of those guys!

Have you tried charging the MTH battery with the MTH wall charger for 24 hours? Track charging won't always fully charge an MTH battery.

If the battery don't hold a charge after 24 hours of charging, then replace the battery.

BCR for sure but these work very well...3/7.99 shipped

Track charging won't always fully charge an MTH battery.

Why would you think that?

Of course, some would suggest the "best" battery is the BCR replacement, then you'll never need another battery.

GRJ, I prefer the other lead you gave me.  I've converted all my PS2.

???? Confused.  That picture is a PS-3 and it has no battery.  It has supercaps.

If you power the engine up and allow it to start up, than turn track power off it should play shutdown sounds.  If it does, the supercap circuit is fine.

To do a conventional reset, power on the engine and keep voltage around 10V.  Press 1W and 5B in rapid sequence.  G

In addition to what George said, the PS/3 stuff always indicates a low battery, ignore that reading.

Unless I'm mistaken or thinking that maybe my issue and this issue are connected, I have several PS3 engines that will occasionally start up full lights, sound , etc. in conventional immediately then go dead if you try to move them. They will then start back up dark with lights for 20 seconds as designed and run fine. I've got several that do that any my LHS has seen it several times...seems to be a known issue.

It should read no battery

Very low battery?

Bill Davis,

    No Battery in P3 engines, as G indicated SuperCaps already in the engine, no BCR or battery required.  If you actually have a P2 engine, replace the battery with a BCR and go from there.  Maybe this was a joke on Guns.

I'll just add this small tidbit to the discussion in the event you're running an older DCS version.  If your DCS software version is an earlier version (pre-3 volt battery PS2 train era), the software will not differentiate between the older 9v/8.4 volt and the newer 3 volt battery.  Thus giving a low battery indication to all the more recent 3 volt battery trains even if their 3 volt battery is fully charged.

I don't think it is DCS software.  The 5V board does the measuring an looks for an appropriate 8.4V voltage.

A PS-2 3V looks for a 2.5V reference.  If no battery installed it see high 5V (no load at the battery terminal).  With BCR added which charges up to 5V it reads low when first turned on and the voltage is 0, and goes to high as the BCR reaches 5V.

For PS-3 it was engine software that wasn't modified to account for PS-3 supercaps.  G

If it i ps1 or 2, definitely a BCR.
