Self Charging Battery Back-up
The special NiCad 2.4v self-charging battery
recharges continuously during train operation
and should last for up to five years. The
battery is a dry battery that 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) 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).
•
Use M.T.H.'s battery recharger (Item No. 50-1019) (sold separately) that plugs
into a wall outlet and a special port under the engine to recharge the battery
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 battery. Available through M.T.H. Parts:
®
(Item No. 50-1024) AA NiCad Proto-Sound Battery (Blue Casing)
®
(Item No. BG4000004) AAA NiCad Proto-Sound Battery (Green Casing)
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.**
