Self Charging Battery Back-up
The special NiCad 2.4v self-charging
battery recharges continuously during
train operation and should last for up
to five years. The battery is a dry
battery that should not leak or cause
any damage to your engine. Depending
upon when your engine was built, it
may need to be charged right out of
the box. If engine sounds seem
distorted or garbled at low voltages or
become silent when power from the transformer is turned off, test the battery to
determine whether it should be recharged or replaced.
Test:
Put the engine in neutral and leave the track voltage at 10-12 volts (high
enough for the lights to shine brightly) for 15 minutes.
Recharge:
If the sounds are improved at the end of the 15-minute test charge,
the battery charge has run down and can be recharged. There are a number of
ways you can do this:
•
Leave the engine in neutral with track voltage at 10-12 volts for 6-7 hours so
the battery can fully recharge (if your engine has a smoke unit, be sure it is
turned off).
•
Use M.T.H.'s battery recharger (Item No. 50-1019) (sold separately) that plugs
into a wall outlet and a special port under the engine to recharge the battery
overnight without leaving it on the track.
Replace:
If the sounds are not improved at the end of the 15-minute test charge,
it is time to replace the battery. Available through M.T.H. Parts:
®
(Item No. 50-1024) AA NiCad Proto-Sound Battery (Blue Casing)
®
(Item No. BG4000004) AAA NiCad Proto-Sound Battery (Green Casing)

batteries in this system can result in damamge to the PS 2.0 circuit board and/or
the batteries.
**Do not use alkaline
batteries for testing or
checking purposes for the 3-
Volt PS2 boards. Using
alkaline batteries will damage
the 3-Volt battery charging
circuit.**
