The two special AA size 1.5v NiCad
self-charging batteries 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 toshine 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 engine to recharge the
batteries overnight without leaving it on the
track.
