Self-Charging Battery Back-Up
The two special AA 2.4 NiCad Battery Pack recharges continuously during train
operation and should last for up to five years. The batteries are dry battery that
should not leak or cause any damage to your engine. Depending upon when
your engine was built, they 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 batteries to determine
whether they 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 and the engine to move steadily) for 15
minutes.
Recharge: If the sounds are improved at the end of the 15-minute test charge,
the batteries 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 batteries 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 tender water hatch to recharge the
batteries 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 batteries. Available through M.T.H.
