Self Charging Battery Back-Up
The special NiCad AA self-charging batteries recharge continuously during train
operation and should last between one and five years. The batteries 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.
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
battery 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 battery can fully recharge (if your engine has a smoke unit, be sure it is
turned off).
•
Remove the batteries and recharge them in aNiCad battery charger.
Replace : If the sounds are not improved at the end of the 15-minute test charge, it is
time to replace the batteries. Replacement batteries can be ordered through MTH.
The batteries are located inside the locomotive boiler. See page 16 for instructions
on removing the boiler from the chassis.
DO NOT substitute alkaline batteries for these NiCad batteries. Using alkaline
batteries in this system can result in damamge 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.**
