3000 mAh AA battery for Flash ?

[surapon]

Dear Sir, / Madam
I Use Eneloop AA Batteries for many years and Love them, But Eneloop =1.2V Min. 1,900 mAh.
Yes, I use to use Energizer 2,500 mAh too, But I not happy about short Life per Flash.
Now, My Photographer friends from the Local Camera club in my home town want me to try the Made in China AA Battery = 3,000 mAh 8 pieces = $ 12 US Dollars

I so afraid that this High Power Cheapo might Kill my Canon Flashes.
What do you think, Sir ?
Should I try ?
Thanks.

Dear Surapon,

I know that you can find Eneloop XX 2500 Mah Batteries. I never used them, so I'm sorry, but I can't give you a feed back on them.

Thank you, Sir, Mr. Click.
I will wait for some of our friends , who know these 3,000 mAh, the Cheapo.
Thanks again Sir.

I've got the Eneloop XX 2500 mAh, and they work great. Can't specifically say about how long they last, but it's a long time. I don't use my speedlites as much for a while, but they certainly have quite a bit of power in them, and if if I need to I don't worry about pulling them out after having left them sitting there for a couple of months. I know they'll still have quite a bit of power left in them.

Dear vSir, Mr. Drizzt321.
Thanks for your information, Yes, I will order more of Eneloop XX 2500 mAh, and will forget about Cheapo 3,000 mAh.

I'd doubt if the cheap battery would ruin your flash, but I'd also doubt that it even comes close to meeting the claimed specifications. Unfortunately, some manufacturers make claims they know are false because they know that few if any will realize it.

If the battery actually had that capacity, it would likely self discharge very quickly. Design of a battery is a trade off between capacity and battery life. Increase one, and decrease the other. Sometimes its a drastic decrease.

Thanks you , Sir. Mr. Mt Spokane
I am glad that I have you and so many Friends in CR as the teachers, and learn from all of you all the times.
Have a great night, Sir.

As far as I know, the AA batteries of higher amperage on the planet are the German "Ansmann" reaching the threshold of 2850 milliamps. Chinese batteries are said to be 4800 milliamps, but obviously a lie. I would only use batteries of known brands, store-bought respected.

+1 on the eneloop XX (in the east they are called "Pro") they are great.
One thing to consider is the life span they are rated as "Can be recharged up to 500 times" where the "white"
eneloops are 1000 recharge cycles.

LOL, why not try the new 3500 mAh imports from Afghanistan :-> ?

* they are unlikely to really contain that much charge, will you measure it?
* they are likely to loose max charge quickly after some cycles
* they will loose charge each day, so you have to actively keep them charged taking turns

There is a reason so many people use LD-NiMH like eneloop - and if you need more power, get an external power pack for your flash(es).

Plenty of photographers put their trust in the 2700 mAh Maha Powerex batteries http://www.mahaenergy.com/batteries/ which are optimized for power intensive devices such as on camera flash.
http://www.protog.com.au/buy/maha-powerex-2700mah-nimh-aa-rechargeable-batteries-4pk/2700H

I've got 20 of their AA cells and ticked the box for the 8 cell smart charger.

I'm constantly amazed at the capacity of these batteries. Find what you want at Protog which seems to have excellent information, then check eBay for local pricing.

I use Eneloop AA batteries (White) , is there a big diffence with the Eneloop XX 2500 mAh in a flash?

 

[cocopop05]

Before I knew any better, I purchased Inca 2700mAh NiMH AA batteries, they did not last particularly long in my 600ex-rt. I then found out about Sanyo Eneloop XX rated at 2500mAH, the Sanyo's lasted about three times as long.

Then I bought a MAHA Powerex C9000 and found the Inca's were only able to hold 900-1100 mAh.

I cannot answer about standard eneloop vs XX. All I know is the XX's last ages.

Don't go cheap and you will have a pleasant user experience.

I too use Eneloops (the 2000mAh version) for flash. It's nice to know that you can keep them and they will still be charged when you use them again.

 

[surapon]

Thank you, Sir, Dear all of my friends and my teachers.
Yes, Most of the time in our life = Cheap, might not good as they promise.
And Trust the brand name that we Know = Better than the New Goods from Afghanistan = Now, But Next 20 years in the future, The Afghanistan Goods/ Products may be Great as Japanese car in 1971= Datsan and Toyopet= yes, It will take 30-40 years to make the products great, after Copy, Copy and Copy from USA, and Improve the product until great as the Lexus, Acura and Infinity.
Thanks again.
Have a great Friday.

If we look at what is written in flash (6 volts) it seems that alkaline batteries are better than NI-MH, because alkaline nominal voltage is 1.5 volts each, while Ni-MH batteries have nominal voltage of only 1.2 volts each one. ??? The problem is that this nominal voltage does not match the use of high current in a short time. In fact, alkaline batteries, measuring 1.7 volts when new, but at the time much energy is drained drops to approximately 1.1 volts. ??? Batteries NI-MH actually has 1.45 volts when they finish loading in a high quality charger, but when too much energy is drained, drops to 1.2 volts. 8) This explains why the recycle time is faster with NI-MH batteries of good quality. The actual voltage at the time of high consumption is higher in Ni-MH batteries, even if the nominal voltage is lower.

Wow, Wow, Wow------Thanksssssssss, Dear Teacher---I learn some thing New and great, to day.

When I recently purchased my Speedlite EX 430 II, it came in a kit with a diffuser, off-camera bracket and among other tidbits, a set of 3000MAh NI-MH batteries. Since the whole kit only cost a few bucks more than the Speedlite, the batteries were obviously cheapos from China (the name on them was "Digital"). I have a Lacrosse Technology charger that has a readout for each battery and keeps track of all aspects of the batteries while charging. I put the batteries through some gentle discharge-charge cycles and could only bring them up to less than 500 MAh --nowhere close to the 3000. Obviously they didn't last long in the flash unit. Stay with the high capacity Eneloops

That's a typical story, I bet you did not demand a refund. That's what the scammers count on.

No, I didn't. The whole kit was only about $10 over the price of the Speedlite so I knew what I was getting, and I was indeed able to use most of the odds and ends. I did leave feedback on Amazon, though.
