❏
1. Plug the battery charger into a 12-volt power outlet
in a vehicle, placing the charger and battery outside the
car, away from flammables.
❏
2. Plug the battery pack into the charger connector.
Be careful - the battery pack will plug in only one way.
❏
3. Rotate the timer knob on the charger to
30
minutes.
Make sure the red light comes on.
❏
4.
IMPORTANT! NEVER LEAVE A CHARGING
BATTERY UNATTENDED.
❏
5. During charging, feel the battery every 5 minutes
to see if it is starting to warm up. A warmed up (but not
hot) battery pack is a sign that it is fully charged. Once
the pack is warm, disconnect it from the charger.
Depending on how much charge was already in the
pack, you may have to disconnect the battery early.
❏
6. Always disconnect the charger from the 12-volt
power outlet in your vehicle when finished charging.
❏
7. After each flight, completely discharge the battery
and remove the battery pack from the airplane and allow it
to cool completely before recharging.
❏
1. Be careful to avoid overcharging the battery!
When you plug the battery into the charger there is no
way to know how much charge is left in the battery
(unless you have just completed a flight in which the
battery was run all the way down). If you put too much
charge into the battery, it will get very hot. This may
result in melting the plastic battery cover, causing the
cells to vent and damaging the charger! Always remove
the battery from your Sky Zap 2 before charging.
❏
2. Remember to check the temperature of the battery
every 5 minutes during the charge. Unplug the battery
as soon as it warms up (before it gets hot), even if the
timer has not yet run down.
❏
3. Charging the Sky Zap 2 battery while your car’s
engine is running can be dangerous, because it
increases the chances of overcharging. For this reason,
you should
never
charge your Sky Zap 2 battery while
your car’s engine is running.
❏
4. If your battery is not completely discharged before
charging, the charging time may take less than 30 minutes.
Again, only let the battery get warm to the touch – not hot.
❏
5. If you use a different battery charger, charge this
battery pack only at a maximum charge rate of 1/2 amp.
A higher charge rate will charge the battery pack too
quickly and heat up the wires.
