Rechargeable Batteries

I have plenty of energizer and uniross rechargeable batteries over the years, which I very seldom use.
Now I am trying to get into off camera flashy stuff.
But none of the batteries seem to hold any charges, and I don't know if it is the energizer quick charger that is at faulty or the batteries are no good anymore.
So, I am looking to get new charger and batteries.
Is Sanyo Eneloop still the people's choice?

Eneloop every time for me. Ordinary NiMH are the work of the devil.

Eneloops hold a charge for ages no worries about them discharging when not in use

Eneloop here to, Once you have tried Eneloops, You will never want to use anything else.......!!!

There are some pretenders out there, They claim to be using the same technology, How good they are is anyone's guess, I'm testing some " Energizer " ones at the moment, But its to early to say how they stack up against the Sanyo Eneloop versions, On the face of it, They should at least be similar, They are also a similar price, However they are 2300 mAh, So slightly more grunt.

But the Eneloops are tried & tested, Can't fault them at all......Grin

Eneloops are overpriced.

These Uniross Hybrio Industria l batteries perform just as well and are much cheaper

Edit - I've had four sets running for the last 3 years and can't fault them

7dayshop 2900 mAh batteries are the best I've tried. I always take several fully charged sets to weddings but hardly ever need to change the batteries in my flashguns. They're also a good deal cheaper than equivalents.

Some of my 2700 mAh batteries are date stamped 2007 and they're still going strong.

Cheap as chips!

Most AA NiMH only operate at 1.2volts, whereas Durcell, Energizer et al, work at 1.5volts, in fact most alkalines work at about 1.7volts.....If, like me you want fast recycling times on your flash, NiMH are fairly useless, I always whack Duracell's into flash. Expensive yes, but I need the speed.

NiZn batteries are rechargeable and can provide 1.7 volts.

And I said NiZn, not NiMH ! Wink

So you did.....Doh, I haven't had a play with those as yet, but they do look interesting, having very quickly just read an article on them.

NiHM just don't supply enough oomph in my flash, but these look promising?........I suppose they'd need their own charger though?

That's not strictly true about recycle times Ade.

NiMh will tend to give faster recycle times, even though they're voltage is lower. This is due to the internal resistance of NiMh batteries being much lower than Alkalines, lithiums etc.

For example, with those Uniross Hybrio batteries in my sb-800 I can get a full power flash every 2 seconds... with Energiser Alkalines (which I keep as emergency spares) it's only every 4-5seconds.

For really fact recycle times, you could try NiZn batteries... they have been known to kill flashguns due to their high voltage output. A Quantum battery pack is really the way forward if you need machine-gun flash speeds. I don't tend to hose people with flash though, so I'm fine with NiMh.

The same info about battery types is provided by Nikon here
