Self-Charging Battery Back-Up
The special NiCad 7-cell 8.4v self-charging battery in this engine
improves performance at any speed. It ensures that power to the sound system
will remain on during directional changes, or when traveling over dirty track
or switches.
The self-charging battery system is automatically turned on or off whenever
track power is turned on or off.
Track power (when applied) recharges the battery, which should last for up
to five years, and the special NiCad battery is a dry battery that should not leak
or cause any damage to your engine. However, even this special battery will
eventually wear down and need to be replaced. When you notice that your
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.
Put the engine in neutral and leave the track voltage at 12 volts for 15 minutes
If the garbled or distorted sounds are reduced, the battery charge has run down
and can be recharged. There are three options to recharge the battery. 1. Leave
the engine in neutral with track voltage at 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).
2. Using M.T.H.’s battery charger (item #50-10005) plug the charger into the
battery port located on the bottom of the tender. (see figure 8) Let it charge for
6-7 hours. 3. Remove the battery (as shown in figure 7, below) and charge it
in any standard slow charge battery recharger, following the recharger’s
directions.
If the sounds are not improved at the end of the 15 minute test charge, the
battery
