Self Charging Battery Back-up
The special rechargeable 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 NiMH Proto-Sound Battery (Green Casing)
