Max speedlight discharges

[Livin The Dream]

Has anyone either tested, or got a decent link to a typical large speed light duration test with eneloop pros or similar? I'm wondering roughly how many discharges you can get out of eneloop pros, under normal working conditions, at half or full power?

That would be an almost impossible thing to do! I use a nikon body with battery grip! I shoot a full wedding 1000 shots plus and battery still full power! Go out on a night shoot and take 10 x 30 second shots and batteries flat! Too many variables

I use Duracell rechargeable batteries! I have 5 or 6 sets of varying amp rating and don't notice much difference! I do have also a set of gold cap enloops! They are good but I wouldn't replace all mine

Different spedlights differ

Are you referring more to the camera Mark?

Appreciate there are variables, especially temperature, but thinking a typical 580EX/SB910 etc with an eneloop pro (2500mah)set of batteries. 50 shots at full power?

I've not used much flash at the odd wedding I have done before but I reckon the December one I have will be quite heavy on flash. So have been contemplating how many spares I really need. I have 5 sets, so should be ample, but I plan to use a couple of brollies for the group shots if the weather is bad with two speedlights at half power which will be quite intense on the batteries.

What does the handbook say? Manufacturers usually quote the maximum number of flashes you can expect out of a set of AA alkalines with a nominal rating of 2500mAh, same as the black Eneloop Pros. It's only a rough guide, but the figures given for larger speedlites is usually at least 100 full power flashes, probably a fair few more from Eneloops.

If you'e really hammering the guns, they could overheat and either cut out or go into slow recharge mode. Doubling up with two guns at half power should avoid that, and recharge faster.

Thanks Richard, didn't realise they quote that figure. Upon checking my Godox 685's they state approx 230 at full power with 2500mah, impressive.

I was going to double up if needs be, but certainly not scared of ramping up the ISO either to save the heads. Was contemplating taking a studio head but keeping it simple sounds a better idea.
