Charging techniques
A) Linear charging
- The charging takes place with constant and linear amperage.
B) Impulse charging
- With this method there is a short amperage "spike" (approx. 100ms) every full second
during the entire charging time. The continuously appearing "spikes" are providing an
amperage approx. 1.5 higher than the main charge adjustment.
- This system was developed to reduce the oxidation within the batteries, which results
in a better cell structure over longer time of using the batteries.
Amps.
C) Reflex charging
- This method is actually a "reversed" impulse charging. The "spike" comes every second also,
but it is much shorter in time (approx. 4ms), much stronger (about 4 times higher) and it "goes"
into the opposite direction. So actually it is a very short, quite strong discharge "spike".
- This system is especially good for older NiCd batteries to give them some sort of refreshment.
