"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,

NimH. I have used all three. The new ones are in the 2500 to 2800 MAH ranges and some will recharge with the right charger in 15 minutes but they get very hot so I slow charge mine.

You should be able to get 4 for under $10

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.

Sanyo has some new NimH batteries which according to a review I read do not loose their charge as rapidly as the all the other kinds.

I think the only way to know what they are is that they are 2600 Mah. I think they are the same ones Costco has in a set of 6 AA and 2 AAA and charger for $20

on Nikonians to the Sanyo site but I can not find it now.
