AAAA Alkaline Batteries (Qty of 2)
Replacement batteries (NOT Energizer as shown) for the newer RailBoss 4 and TrackSide R/C Transmitters. Quantity of 2.
(Older transmitters use one CR2032 Coin Cell Battery, available at your local stores).
Note: Since our transmitters only consume power while a button is pressed, the batteries will last a very long time; months to years, depending on your usage.
