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.

Lift Out Battery
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:
Battery Charger Port
·
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 (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.
DO NOT substitute alkaline batteries for these NiCad batteries. Using alkaline
batteries in this system can result in damage 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.**
