Battery Care - Best Tugs BRAVO 5 User Manual

Battery Care

Your tug has a smart charger
with trickle charge and battery
maintenance cycles. To charge,
plug the charger cord into the
tug, then the power cord into
a standard power outlet. You
cannot overcharge when using
the included charger.
Always turn off the master
switch when charging.
We suggest charging your tug
when the battery falls below
around 70% (at rest) for optimal
battery life (for sure before 30% at
rest). Note: The tug continuously
and instantaneously calculates
the state of charge, which is why
the percentage fluctuates while
moving your plane. We have seen
as low as a 10% charge displayed
when using a fresh battery and
moving a heavy plane. To read
the resting battery's charge,
leave the tug at rest for at least
60 seconds. We have seen a 10%
drop from freshly charged just by
moving the tug in and out of the
hanger. The discharge rate is non-
linear.
If you notice shorter times needed
between charges, your batteries
are beginning to wear out.
Lead Acid batteries are
surprisingly delicate—damaged
by direct and indirect effects:
environmental, user induced,
misapplication, and on and on.
For instance, charging with
a voltage above 14.4 volts or
