Battery Care

Some precautions should be taken to maintain the performance of the
rechargeable NiMH receiver pack in your model. Improper use of the
battery pack could result in personal injury or damage to your truck.
Only use approved chargers for NiMH battery packs (such as the Traxxas
TRX Power Charger). Do not exceed the maximum charge rate of 1 amp.
Do not short-circuit the battery pack. This may cause burns and severe
damage to the battery pack
Do not burn or puncture the batteries. Toxic materials could be released.
If eye or skin contact occurs, flush with water.
Store the battery pack in a dry location, away from heat sources
and direct sunlight.
Nickel Metal Hydride batteries must be recycled or disposed of properly.
Do not completely discharge the RX Power Pack or you could damage
it. Do not use dischargers on the pack. Store the battery with at
least 25% charge. Stop running and recharge at the first indication
of reduced voltage.
After connecting a fully-drained battery to the charger it may take up to
15 seconds for the charger to sense the battery and begin to charge. To
start charging immediately, plug the battery pack into the charger and
then plug the charger into the wall socket.
