Ni-MH-Delta-Peak (-
∆∆∆∆∆
Peak) trigger voltage
It is possible to adjust the trigger voltage (in mV
per
cell!) of
the automatic termination circuit for Ni-MH batteries.
However, Ni-MH batteries have a less pronounced voltage
drop than Ni-Cd cells, and a practical range has proved to
be 5 ... 25 mV / cell. If the trigger voltage is set higher, there
is a danger of overcharging the battery; if set lower, there is
a danger of premature termination.
We recommend that you carry out a series of test charges
to establish the ideal trigger value for your batteries. Start
with 5mV / cell.
