2-8-8-2 STEAM ENGINE
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.

: 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.

: If the sounds are improved at the end of the 15-minute test charge, the batter-
ies 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.
