"Wich batteries are better for a flash: alcalines or ni-"
Buenos Aires, AR
Hi, I'm using an automatic Sunpak auto383, and I've no money to upgrade to a SB600 or SB800, so I want to take the best from my current unit. I guess this question goes for flashes using AAs in general. Which type of cells gives better performance (shorter recycling time and/or more firings per pack of batteries)? I'm more interested in shorter recylcing times, so maybe oen of you experienced a difference when switching from one type to the other. Regards and thanks,

The only thing you need to watch out for is the trigger voltage. Depending on the voltage it could be fatal to your camera if over the designed max. My D70 manual says the D70 is OK to 250 volts, which is OK for my Sunpak 611, but I think my old Strobonar is way above this.
Check the manual to see what the max voltage you camera can handle. If you have a friend with a DIGITAL multi-meter or an electronics shop nearby, ask them to measure the voltage across the hot shoe after the flash has FULLY charged. This will tell you if you can use it on your camera or not.
note: you need to use a digital meter because you need HIGH impedance meter that will not trigger the flash. Even so, I have one flash that will trigger with my digital meter anyway. If it triggers the flash, you can't measure the voltage.

The NiMH should give shorter recycle times due to lower internal resistance, especially in cold weather. One thing to watch out for is that NiCd and NiMH will self discharge at approximately 3% and 6% / day respectively. So if you use the flash occasionally, you need to make sure that you charge the batteries if they have been sitting a while. NiCd's, and NiMH's to a lesser degree, generally do not like this type of use and should be discharge fully and recharged from time to time. Stan
