I saw even 2500mAh NiMh somewhere,
that's fantastic, but look at it practically.
15V Nicad packs with 12 110 mAhs has capacity for 40 rolls,
How long time would you use the Grip with 2500s? The answer is maximally
2 monthes, because of very high self discharging 1,5%/day.
Why Alkalines were "faster"?: 12*1.5V > 12*1.2V.
But internal resistance of alkalines is poor (high).
NiCd is best of all in this parameter, but has lower voltage.
If you used 15 Nicds with voltage 18Volts the same like 12 alkalines
you would get the best results. Catalogue mentiones
"large potential power supply 12-16 Volts", so it's not
recomended to exceed 16 Volts with "hard" sources.
I think 1/3AA 110mAh Nicd cells are not so hard to damage
relay contacts in the Grip and MD1/2 electromotor(s) and
electromechanical contacts. In fact fps was 5.4 with MD2, roll
loaded and 15*1/3AA Nicds.
I don't like alkalines, because they do NOT work in cold.
But anyway, this is really NOT important for taking pictures!
