What are the mAh capacities on the Rayovac Hybrid AAs?
What are the mAh capacities on the Rayovac Hybrid AAs?
The Hybrid's are under $10 here at local Walmarts for a regular 4-pack. The capacity for the AA is 2100mah and the AAA are 800mah.
Great info on the batteries OVF...
I just got a C9000, and it's excellent...still learning how to use it...seems to have rescued my Energizer 2500's that have been idle for the past 18 months.
My C9000 gave my Hybrids an average 2050 mAh and my Eneloops 1950 mAh.
My brand new Titanium Enduros tested on my Maha c9000 after refresh cycle tested at well OVER 2100 mah, more like 2400 so I am assuming the 2100mah is after losing some charge due to storage. Any way I am very happy with them, just wish they were cheaper! Also the only place I was able to find them was at Amondo Tech. While they are a great co. a little competition might help the consumer. I have heard they are just re-labled Rayovac hybrids, any confirmation Wayne?
Sony are now selling AA LSD batteries in their CycleEnergy range (NH-AA-B4K). Rated at 2000mAh these are stamped Made in Japan so they are probably rebadged Eneloops.
Might want to add the Kodak Pre-Charged AA and AAA to the list -
on Kodak USA web site -
They sell @$7.88 4pk from WalMart
Couple of threads here on the Kodak Pre-Charged -
new Kodac "Pre Charged" NiMH batteries?
Kodak Pre-Charged NiMH
Chevrofreak tested the Kodak Pre-Charged, and seems to think well of them -

Posts #13 and #14 in new Kodac "Pre Charged" NiMH batteries?
OK, here's another - Hahnel Synergy:
I wonder why the Hahnels and some others are only rechargeable up to 500 times and the Eneloops and others are up to 1000. I realize these are both optimistic marketing ploys but still, seems kind of like a no brainer since the price for all of them are basically the same. Wouldn't you go with a cell you can supposedly charge 1000 times over a cell only giving you around 500? Just kinda wondered about this. Doug
Grateful friend of Bill W.
I have now updated the list of "LSD-cells" in the first post in this thread.
I am sorry for the delay! Still using the Eneloops I bougt from CPC in the UK and I could not have been more saticfied. /LRE
Just want to inform you that The PowerBase Instant Battery is being sold at ACE hardware stores and SM Workshops (Philippines) for 995.00 PHP (that's roughly 22.00 USD).
- 4 x AA 2100 mAh
- 4 x AA 800 mAh
- Standard Overnight Charger
In my opinion this one's a steal, and some shops sell the Sanyo Eneloop at insane prices (132.00 USD for a charger and 2 x AA's)
SilverFox/Tom in another thread mentioned -
Radio Shack Pre-Charged.
web page claims -
"- Last about 500 charging cycles, reducing the number of batteries dscarded into the environment
- 1.2V/2000mAh capacity
- Hold approximately 80% of their charge for a full year"
Priced at $19.99 for pack of 4
that sounds really expensive -
more than double for most other LSD AA prices.
Anyone have more thoughts on this claim by Sanyo?
Here are graphs of an Eneloop and two Sanyo 2300 mAh cells, one old and one new. As you can see, the Eneloop voltage is higher than the old 2300 and lower than the new one, for most of the discharge period. This is of course a test of only three cells, so can't be used to draw any general conclusions about Eneloop voltage -- except that not all Eneloop cells have higher voltage than all other NiMH cells.
Anyone who has a concept of a battery as a constant voltage source should read this.
I'm questioning Sanyo's claim that their 2000mAh Eneloops are as powerful as 2500mAh NiMh batteries. How could that be true unless the Eneloops had a nominal voltage of 1.5V...and that can't be true (as seen in the graphs that you've provided). So I was just wondering if anyone has seen evidence to back-up Sanyo's claim.

Combined with a higher voltage during discharge, it's quite possible that a 2000 mAh rated Eneloop could last longer than a lot of 2500 mAh rated cell in some devices.
If the device in use will discharge the cells to a sufficiently low voltage or the 2500 mAh cell is of decent quality, it's still likely that the 2500 mAh cell will last longer than the Eneloop. (Assuming that self discharge hasn't played a part)
Pure Energy NiMH Pre Charged
C$12 at WallMart Canada for AAA4
RayOvac Hybrids are C$14
The Source by Circuit City still wants C$30 for a 4 pack of Eneloops
In Post #49 (link) over at the PentaxForums for use of LSD (Uniross Hybrio) and NiMH (Energizer 2500mAh) in a Pentax K100D - a dSLR that's pretty sensitive to batteries - it's in a thread called -K100D - "Low-Battery" Problem
"I'll just add a few facts as measured with my particular K100D........
Battery meter shows full charge at > 1.25v per cell, i.e. >5.00v
Battery meter shows half charge at 1.25v per cell, i.e. 5.00v
Battery meter shows empty and camera shuts down at 1.19v per cell, i.e. 4.76v
I'm an electronics engineer and took great care in taking these readings by the way, it's very easy to get it wrong. Other K100Ds could be a bit different of course, and temperature may be a factor possibly, I'm not going to repeat these measurements to find out.
As far as batteries are concerned, Uniross Hybrios are SO EASY to live with, I get 5-600 shots over just about any period of time I'm ever likely to leave them in the camera and they outlasted a friend's Canon 5D Li-On batteries at the same airshow and I took more pictures, so where's the problem? I've about 9 months experience with these batteries, they're great.
Energizer 2500mAh (Sanyo manufactured) NiMh batteries last for 900 shots if used the same day as charging, but may only get 2-300 after a week or two. Now, I've measured the remaining capacity of Energizers after a 2 week rest, and it's hardly dropped at all, what's happened is that the voltage has depressed to a level where the K100D cutoff voltage is approached, so only a couple of hundred shots max is likely whereas there's actually plenty of charge in them for 2 or 3 times that. So, when the K100D says they're flat there's actually 75% of the charge remaining. Hybrios' voltage doesn't depress so much after a rest period so still can deliver most of their charge into a K100D."
Another CPF thread with the same theme -
My Eneloops charge to and hold a higher voltage than other LSD's
I'll probably just stick to my Rayovac Hybrids (though not claiming they're better than all others). Thanks.

Even better, at Amazon is the 4 pack of AA for $9.39. Get two of these packs for a total price of $18.78 ($1.21 cheaper than buying the 8 pack).
