Interesting observation...
I googled for "eneloop flash recharge time" and found several links.
Another interesting read is the Performance testing of Eneloop AA 2000mAh vs PowerEx Imedion AA 2100mAh NiMH Battery
eg.

http://www.photomalaysia.com/forums/showthread.php?t=73833nb: I misunderstood your post when you wrote recharge time to mean battery recharge time..
Rupanya you were refering to the flash recharge time... aiyyaa

hehe

read that already, and i also very sorry lah for my bad english!

vandechrome, I have not found my batteries to recharge any faster if I have higher capacity batteries.
I have 4 Energizer 2500 mAh AA batteries and 4 Sanyo Eneloop 2000 mAh AA batteries. Both take 4 seconds to recharge from a full 1/1 power blast (press Test, then wait for the light to come on again in 4 seconds.)
Do you mean that when you fire one 1/1 blast, then fire another 1/1 blast in 2 seconds, that second blast has much power as the first one? I always presumed that I will only get full 1/1 power again when the Test light comes on again after 4 seconds. I usually don't fire one shot then wait 2 seconds; I most certainly always fire 2-3 shots in burst mode of 5 FPS (so it's 0.2 seconds between 2 flashes). This is to lower the chances of blinking eyes (and have a chance to merge pictures where different people blink.) If I was to shoot again in 2 seconds I'd certainly have a hard time realigning the flashed images.
The Eneloops however are low-drain batteries so they still have power after a week whereas I don't know if the Energizers will. So I always prefer to put the Energizers in the flash to use first, then switch to Eneloops when the Energizers are finished. I always carry alkaline AAs as backup for paid events.
hafeez71, yes the Imedion makes a good backup set.
From what i read and wat i learned before buying my batteries pack a year a go, mAh determine how fast the current can flow, yes, it will have faster charging time and also faster discharge time, so based on theory, more current flow or conductivity, more faster recharge time for the flash, i dont know about ur situation, because u are using F58, but with my situation, using manual power level and usually bounce the flash, that wat i can conclude.
yes, i'll wait until it fully charge before another blast.

If your flash is eating batteries:
- don't be a pixel peeper, use a higher ISO! ISO400 at least. People ask you to shoot events
to catch the moment, not to pixel-peep at how sharp an uncle's moustache can be at ISO100 F8
- remove diffusers if shooting over large distances, it makes no difference.
- point your flash forwards instead of bounce for much, much faster recharge times.
vandechrome, forgot to note that I use TTL all the time so I don't have a good idea whether I'm at 1/1. Though I'm usually on ISO400 onwards so chances of that are lower. Also back on my old F56, I could hear the full recharge sound, but I know that I rarely heard it so I know I don't hit 1/1 in TTL much.
the full charge sound always occured when the batteries near to die..hmm, i guess we need another TT for this experiment...
