John the Energizer batteries are well if i may say _rap when they first came out i bought them for my boom box to see if they compared to duracell that takes ten D batteries and they only played tapes for @ 2 hours and after that you couldnt use the volume past about 3-4 this was to go on a camping trip with which was terrible due to the lack of music because of the batteries. My Duracells will play the tapedeck for three days straight.
I alway use Duracell and have many of the AA that are the NiMH type and they work well in everything i have they have one that comes with a fast charger that will charge them in an hour only thing is when you buy new batteries it is best to get a new charger as well because the cost is ony a couple dollars different hope this helps.
You can also get them with a slow charger but remember NiMH needs to be discharged completly before you can properly recharge them.
They can be purchased at Wal Mart and anywhere where batteries are sold.
Here is the power rating 2650 mAh AA and a link for you to look at http://www.theessentials.com/products/H58716.jsp
Google Duracell NiMh batteries and it will take you to the website for Duracell. |

Also John like everyone here says buy the best once and you need not worry. Only buy namebrand batteries anything else is a waste of money some things i power with my AA's are Bearcat scanner,Radioshack scanner,Sony camera,Lowrance GPS,Motorola weather radio,OTC computer scanner,AC sniffer,many led flashlights,A Tom Schultz Rockman portable guitar amplifier,and many more things not mentioned good luck. |

I think I use the same batt's for my canon light. I've never had this problem but when charging on the 15 min charger I notice the blinking sometimes which indicates that one battery is not working properly. I'll drop it on the ground from about 3 feet a few times and it's back to normal. After a while they do fail permanently so I'll save them and buy new ones and return the non-functioning ones. I used to hate swapping them out all the time with fresh ones so I got some alien bees lights and battery (vegabond). I use the speedlight for night shooting with high iso at low power and stuff. |

I use Ray-O-Vac NiMH 15 min. rechargeables in my SB-800s and haven't had any problems. The charge seems to last forever. I've also been using the same batteries for almost 3 years and can't see any noticeable loss in charge. (It also helps if you have/use the fifth battery attachment for the SB-800). |

I use the rechargeable energizer batteries. I have them all over the house in my kids toys. |

If I could afford a SB-800 Speedlight then I would also purchase a High-Performance Battery Pack SD-8A. It uses 6 AA batteries and provides extra power to the SB-800. I used the High-Performance Battery Pack with my SB-24 and F4 for years. The 10 batteries working together had plenty of power and the recharge time between flashes was excellent. Ten batteries outlasted 4 batteries by a long way. The High-Performance Battery Pack is slim and easily slips into a pocket or could be worn on a belt. (The new ones look like the old ones.) I would also pitch the NiMH batteries and purchase non-recharble Duracells. I have not needed any lately but in the past I have purchased them in packs, of 20 or so, at Home Depot at a very low price. |

I use energizer "Industrial". Rechargeables burnt out a pocket wizard last year and aren't made for that.. i just buy a pack with 10 4 packs, Last about a year and don't have to carry extra stuff like chargers around or on the road. No Problem.I use a lot of batteries. And I like them fresh. |

Just a thought but some of the issue may be due to voltage rather than the capacity of the battery. Voltage is the force behind the battery whereas current is merely the capacity expressed in mAH
Single cell alkaline batteries tend to have an output voltage of 1.5v -1.6v. However, NiMH have an output of only 1.2v.
In most cases this difference doesn't seem to be a problem but in the case of products that need all the juice they can get then it can make a difference.
A flash that needs 4 batteries will get 6v from alkaline but only 4.8v from NiMH. That may not be enough to load the capacitors in a heavy duty product.
All the current in the world goes nowhere with the voltage to push it. |

Everything that PJ has said here is correct, I just want to clarify one one statement he made
"Voltage is the force behind the battery whereas current is merely the capacity expressed in mAH"
As it it is not quite clear enough.
I will try to make an analogy for you.
Imagine we have a container of water (it does not matter how large, but we elevate it it 1.5 yards above the ground, this is the potential difference or "voltage".
Now if we connect a drinking straw from our container and allow water to run through it back down to the ground, the speed at which the water flows is the "current" just like a stream, and is expressed in Amperage, or in the case of a battery it is expressed in milleamps per hour (the current capacity and the longevity). By increasing the size of the straw, say to a garden hose, the water can flow at a faster (greater) rate, if we go to a larger hose the faster the flow hence the greater the current.
A 2500mAH battery (or 2.5 Amps) will give that current for 1 hour, or any other combination that comes up to 2500mAH. Like for example: 250mA for 10 hours, or 25 mA for 100 hours.
In a flash it is the voltage that gets charged into the capacitors that fire the strobe, if as PJ pointed out you have a lower voltage, it will never fully charge. It is the current capacity of the battery that determines how fast the flash recharges, so both are equally important. |
