Self Charging Battery Backup
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
batteries 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. (See figure 15)
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. Parts. (See figure 14)
DO NOT substitute alkaline batteries for these NiCad batteries. Using alkaline
batteries in this system will result in damage to the PS 2.0 circuit board and/or the
batteries.
