The battery housing must not be fitted with NiCad batteries! The contacts of the battery housing are only intended for alkaline manganese batteries.
The lower resistance of NiCad Batteries means that more current can flow, and this can damage the flashgun. (..) |
Any idea if Ni-Mh could be used?
I've been using them with modern flashes. _________________ MF: Kodak DCS SLR/c; Samsung NX10; OM-10; Canon T50

All are used batteries.
Duracell Aerocell Super-Alkaline 0.28 ohms.
Duracell ProCell 0.26 ohms.
Varta Alkaline 0.30 ohms.
Panasonic Ni-MH 0.25 ohms.
Tecxus Ni-MH 0.24 ohms.
Does this make a difference?
edit: corrected the ohms, damn USSR meter. _________________ MF: Kodak DCS SLR/c; Samsung NX10; OM-10; Canon T50

I have used both NiCa and NiMe on older flashes.
What to be concern is the high ampere rate of these batteries. Full power continously after 30-40 shots will melt down the battery compartment and deformed metal springs. These parts need to be replaced. I also had modified several of mine with thicker internal electrical cable or, if place is problem internally, added few more thin cables.
I have been used these batteries with maximum 1/4 power. No problem so far, as long as you aware of heat problem.
Now, if i need power, I use many flashes, bundled with cheap eby radio receivers, but still at 1/4 power. Old manual flashes cost me approx 10euro a piece.
edit: high Ohm low ampere rate |

Ok, thank you. The basic problem is this, I can deal with that, just turn it off when the handle starts to feel too warm.
I was afraid it would disturb the electronics or explode the capacitors which is not nice when they are just about where my left eye is. _________________ MF: Kodak DCS SLR/c; Samsung NX10; OM-10; Canon T50

Here is something but I don't understand the ohms and amperes, I studied to be a mechanical engineer. _________________ MF: Kodak DCS SLR/c; Samsung NX10; OM-10; Canon T50

The site has some good hints on rechargable cells.
I have 50+ AA NiMh 2300 mAh and use them with flashes.
My charger is per cell, designed for NiMh.
I also nummerize 4/6 batteries as a set (a1, a2, a3, a4, b1, b2...) and always keep them as a set for ease maintenance/charge/discharge. I may depend on these cells one day. |

$89.85
I got most of my Ni-MH:s from a local store for a give-away price. Something like 1,50 € for a charger and 4 AA-s. But they are probably not the best quality. I've usually tossed the chargers away and kept just the batteries. _________________ MF: Kodak DCS SLR/c; Samsung NX10; OM-10; Canon T50

The MAHA does both AAA and AA batts, if that lessens the sting. Having a smart charger that will drain out
whatever residual power is left before recharging is a definite plus. Using a cheap charger, my batteries were
crapping out in half the time as they do now. |
