Hi people, please could someone recommend me some decent rechargeable AA batteries for my yonguo flash. I've been looking on the aegis site and there seems to be so many different 1s with different mah and I'm not sure what I'm meant to be looking at. Any input appreciated.

Thanks. Kris
 
mAh is basically how much power the batteries will hold, so the bigger the number the better.

What he said. I use these batteries in my model planes to power the servos/receiver and in my transmitter. They hold their charge really well. Only other battery would be the 123 cells, they charge really FAST!! and are the safer alternative to lithium polymer cells. Higher mah = better power delivery and longer lasting between charges.

Is there a quick charge charger anyone recommends aswell to go with them?
 
Well with the current offer on 7dayshop it would only cost you an extra £1.10 to get a charger with a pack of 4xAA batteries although doesn't seem to be the quickest.
 
Does anyone know where I can find these in shops. Do any stores stock them?
 
I use the Eneloops in the controllers for my consoles and tv remotes, etc - devices that might not be used continously. So a battery that doesn't drain (quickly) when not being used is ideal. But I'd have thought something with a higher rating would be better for a flash (high drain device). Eneloops are 'only' 2000mAh.

I used these in my Speedlite.

I've asked the same question about batteries in the last week on here and 2 other sites and everyone recommends the Eneloops.

There must be something about them. :)

I am sure I have read somewhere too that sometimes, the more powerful isn't always the best:)
 
'Some' rechargeables 'may' cause overheating with 'some' flashguns...

I've tried several types of rechargeables and following an off-the-record chat with the Nikon and Calumet peeps at Photokina, have gone back to Duracell disposables in my SB900's instead.

Spot on...

I have two Oly FL-50 dedicated flash guns which are fine with any battery, but I recently purchased 3 Yongnuo YN460-II's for some off camera strobe stuff and when I used one of these with Duracel 1700 mAh rechargeables, it overheated after 5 mins of use, rendering it u/s. Supplier quickly repalced the unit, but it makes me weary when I use these rechargeables with the Yongnuo's.

mmm... interesting, I use Eneloops in mine and it's not blown up yet- then again it's not like I use the machine gun approach of many so I've not even managed to overheat mine either which seems to be a complaint from some.

In fact, I was using my flash earlier - good job it was -3 outside so no issues with overheating:lol:

I do charge mine properly- none of this quick charge rubbish though I suspect they think there could be an issue with the chemical reaction in these types of batteries?
 
Batteries get hot when you charge them, especially quick-charge. They also get hot when you discharge them, 'strenuously'. Seems logical that a higher capacity battery, being used 'energetically' might also get hot, hotter than a lower rated battery. But I've never known it to cause any problems in the device I'm using them in. Interesting...I'll definitely keep it in mind.

Annoying music, but it tells you why and how to avoid it.

Basically rechargeables are 1.2v and disposables are 1.5v
The mAh has NO EFFECT on voltage rate. It is simply a measure of battery capacity.

Disposables have an average mAh of between 1,700-3,000mAh, while rechargeables have between 500-1000mAh for NiCd and 1,300-2,100 for NiMh batteries.

This is the batteries' capacity, not it's output rate. Don't be confused thinking they're the same.

Buy good quality (expensive, yes, I know, but cheaper than a fried Speedlight) disposables and you'll avoid many of the problems people have been complaining about.

Thanks for all the info. How would I know if my yongnuo has overheated? Ive used duracell but only seem to last a couple of flashes.
 
I use an Energizer charger purchased from Tesco's last year.

In my flash units I use 4 x 2450Mh which are again Energizer, and in my receivers (which take 2 AAA's) I use 700Mh Energizers, which in my experience last a very long time and havent had any issues with overheating,

It gets hot...it stops...you have to buy a new one.

Buy proper batteries and you'll be fine...
I swap them out after more or less every job unless I only fire a couple of flashes.

Thanks, good info on mute;)

Seems the way I operate is fine for but worth bearing in mind should any of that change

Just to point out though, that I had only inserted the batteries and NOT used the flash - which caused the Yongnuo to overheat. I'd say this was more a faulty flashgun than caused by the specific type of battery I inserted.

Strange though, but as they're only £35 a pop, you get what you pay for, eh!:D
