Atomos Ninja-2 – User Manual Edition 1: November 2012 7
Batteries
The Ninja-2 is a battery powered device, and has a special feature to
ensure that you never have to interrupt a recording to change a battery.
We will come to this shortly.
Like all batteries, you will need to take care of them. Make sure that you
don’t short circuit the connections because this can result in very high
currents that can damage the cells and could pose a fire hazard.
Charge new batteries before using them. The supplied Ninja-2 charger
can charge two batteries simultaneously. There are four red LED
indicators for each battery. This will show the approximate stage the
charging process has reached.
Batteries do not charge in a linear way. At first they charge very quickly,
and then the rate slows down to a trickle. While charging, one or more
red lights will blink. When 90% charge is reached, all the lights will flash.
It is perfectly OK to use the batteries at this point and we recommend
stopping at this stage for the longest battery life. If you leave the
batteries on charge after all four lights are flashing, the charger goes
into trickle charging mode for the final 10%. Eventually, when trickle
charging is complete, and the batteries are at 100% charge, all the
lights will go out.
Always use battery slot
for the first battery. This is effectively your
primary battery and the Ninja-2 will not start without it.
Battery slot No.2 is the secondary or back-up battery and is not marked.
Once the Ninja-2 has been started from battery slot No. 1, it will operate
on battery slot No. 2 alone. No. 1 is only required for start up.
To insert the batteries, gently slide them down into the slot and lock
them into position. To remove a battery, push the latch to release it. Each
battery has its own latch, which is located to the right of batter No. 1 and
to the left of batter No. 2 as you look at the back of the Ninja-2. Pull the
latches towards the batteries to release them.
Ninja-2 batteries and modular accessories (Connect Converters, etc)
are held in place very tightly because they are on the outside of the
device and there has to be no possibility whatsoever that they could
work loose, so you will have to be quite firm with the battery latches.
We suggest that you familiarise yourself with the force required to
remove the batteries and accessories so that you can do this quickly in
the field. Make sure that you hold the top and the bottom of the battery
or accessory module when sliding it off to avoid dropping it when it is
released from the main unit.
The Ninja-2 introduces an Atomos technology called Continuous Power
which used battery looping. When power is running low on one battery,
the Ninja-2 will automatically switch to the second battery, you can
remove one of the batteries and replace it with a fully charged one.
Ninja-2 will continue to operate as you do this. You can continue this
process indefinitely.
The Ninja-2 may be powered from NiMH & Li Ion 14.4V battery
systems. Battery adaptor required.
