Important Information on NiMH Batteries |
To achieve
the best performance out of our NiMH packs, there are several things to keep in
mind while using and charging them. Please read the
following:
Notes on use of NiMH batteries:
-never
dishcharge pack completely (optimally, voltage per cell should never fall below
0.9V)
-NiMHs aren't the best at maintaining a charge over long periods of
time, so if your charged pack has been sitting around for more than a week or
so, top it off before flying (this is when peak-detect chargers are really
handy)
Charging our NiMH packs:
-Charging NiMH battery packs for the first time
may require a trickle charge to wake them up
-Never charge at a rate greater
than 1C (typical charging rates range from 0.5C to 1C), where "C" is the
capacity of the battery in mAh. Therefore, to determine the fastest charging
current in mA, simply multiply the capacity of the battery by one.
-Never
overcharge packs.
-Auto-cutoff charger for NiMHs is recomended. Set Delta
Peak to 0.01-0.02V for adjustable chargers.
-NiMH batteries tend to get
warmer during charging than NiCds, so whenever possible, remove battery from
aircraft during charging to prevent excessive heating of the battery (mainly
during a fast charge).
-NiMH batteries SHOULD NOT be cycled. NiMHs do nut
suffer from the "memory effect" as do NiCDs. You can top NiMHs off at any point
during their use without having fear of damaging the battery.
 PLEASE
RECYCLE your old batteries.
