The NiMH (Nickel Metal Hydride) RC Battery
The NI-MH RC transmitter battery will last about 5-6 hours on a full charge. Charge the battery
for about 14 hours. A charge jack is provided on the transmitter for recharging its internal
batteries. This round jack is located on the right side of the radio control. (See the radio control
diagram) The RC power switch must be in the off position when the charger is plugged into it
and must remain in the off position while charging. A light on the charger will be on, when
charging.
To avoid a RC battery going dead during a presentation, start the program with a fully charged
battery or be aware of how much charge there is left in the battery. If you have an extra battery
you can change batteries and keep going.
To install the NI-MH battery pack you need to take the battery cover off the RC. Disconnect the
RC battery and put the NI-MH battery in its place.
NI-MH RC Battery and Charger Specifications
NI-MH RC transmitter battery 9.6 Volts 1500mAH
NI-MH RC transmitter battery charger 11.6 Volts 130mA
Caution: Do not overcharge the batteries as this could cause permanent damage to the
transmitter batteries. (Doubling the normal charging time is the type of over charging that is
meant here, and the battery getting hot.) When the battery level needle goes in the red, the
robot should be turned off because the robot could act erratic without the transmitter signal.
