As much as I loved reading this article it's a bit of a waste for us Europeans. Of all the batteries tested, only the GP and the Energizer is available here in Norway. I'd love to see other brands tested as well. I currently use GP, Sanyo, Hahnel and Energizer. cheers,.

I was wondering why the Sanyo Industrials (Green Batteries) weren't tested? I know they're not readily available at stores and such but it would be nice to know how they stand up to their labled brethren. JP..

Useful, but is you had included Strobes in the mix as well as digicams, the even higher drain ~5 amps that they require would have given more information...

Comment #3

What about the issue of voltage? As far as I know, all of the NiMH batteries are only 1.2 volts. Why aren't they 1.5 like ALL of the AA alkalines they are replacing? Doesn't the device suffer from the lack of voltage? I bought some Energizer NiMH to use in my Canon flash, but I'm not sure if they are compatable. According to Canon, since they have not tested them, they do not recommend them. So now I'm using them in my cordless mouse and Mini-Mag Lite. And the Mini-Mag is very dull. Also they don't seem to last any longer in the mouse.

 Thoughts, comments?..

Very useful, but the value conclusions are not usable because they are based on retail prices that are not listed anywhere that I can find. The conclusion that the Ray-O-Vac are high priced compared to the other top 2 doesn't match my experience of $10.99 per 4-pack for the Ray-O-Vac at WalMart vs. $11.99 per 4-pack minimum price for the other 2 anywhere I can find them. Am I paying to much for the PowerEx or did the reviewer pay too much for the Ray-O-Vac?..

The test left out the new 1800 Nexcell AA, GP 1700 mA, and the new GP 1 hour charger (with thermal protection). All of them are high end batteries and chargers that whould be included. Regards, Michael...

Comment #6

Would be great if you could comment on the battery weight (are they all quite similar) and on lifetime (number of recharge cycles).

Thanks prasanna..

Comments on the battery shoot out.

1. Please add Sanyo 1600ma and panasonic 1600ma nimh.

2. All cams, I know of, have internal regulators to 3.3v for the electronics and straight thru for the motors. The design of the load circuit assumed that there was a resitive load. NOT. The regulator will reflect a constant load(current) to the batteries no matter what the input votage is. This is what is critical.

Usually 1V per cell. But the load must be a constant current to meet the industry test specs. If you use a 3.3v LDO regulator for the buffer between the batteries and the resistor(3.3ohm) you will get a true reflection of the batteries capacity. One type of regulator that will change this is the buck switcher. The load(current) the battery sees will change for varying input voltages since it is a constant power delivery device.

For most of the digicams the LDO series regulator is the one used and the testing should have reflected this configuration. Walter..

Dave: Your Battery Shoot-Out report is another home run!! Granted a number of fine points in the early responses in this BB, you have stated that the results reported so far are preliminary, and will be updated pending time available. Here's another fine point to consider:.

  I've been a satisfied user of the MH-C204F charger for over a year, generally with 4 sets of the Kodak batteries (which get used only in my Nikon 990 camera). Tried to use a set of older Samsonite (Quest ??) batteries in a battery operated lamp of my wife's. After discharge, the C204F refuses to handle them. In your test, you might consider looking at what happens to rechargeability (battery life, ...) when one lets the voltage get well below that 1v per cell limit you mentioned. Thanks again for taking on this study ... Ken Bowles..

I have the RayoVac rechargeable AA and AAA alkaline and many of the AA and AAA leak. Recharged them 3 - 4 times. My nicads of 5+ years, 600 ma are still going strong. once, of the 4 AA's left in a charger, the RayOVac leaked, other Nicads didn't. Don't give me any crap about "special chargers" for RayOVac - I've used R. Shack's, "special" Nimh chargers, Sanyo, GE, Archer and other cheap ones - only the RayOVac leaked. Unless of course they are not meant to last considering the fact rechargeables are not popular in the US !.

I have GP and other general brands 1200/1400 maH Nimh and use them in digital cameras, Canon Flashes and other flashes and mainly in my son's toys and so far none have leaked or died out. Avoid RayOVac, unless you don't mind cleaning up the mess...

"For most of the digicams the DO series regulator is the one used and the testing should have reflected this configuration" Where did you get this tidbit that a 3.3V DO regulator is used in most digicams? How many digicams have you taken apart? I cannot believe that many high end camera manufactures would throw out so much battery power heating up an DO regulator, when switching regulators are more efficient and smaller. (linear regulators are big cause the get so hot). If the camera can run on alkalies (well over 7V fully charged), pulls and amp and uses a linear regulator, this means that more than half the battery juice would go to heating the regulator and the regulator would be dissipating about 3.5W, thus requiring a pretty good heat sink. You are picking on an excellent test set up...

Comment #11

How many times were the batteries discharged and recharged before the test measurements were taken? At least three cycles is needed to reach peak charge. In usage, like in the D7, there is a minimum voltage cut-off that kills the camera if the current drops below that point, so it doesn't matter what the battery has left at that point, as they can no longer run the camera. Can you address the cut off voltage for a camera like the D7 in your tests in some way? Were all batteries cycled at least three times thru a discharge/charge cycle to make sure the tests actually mirror the reality when using them?..

Qoute: "I have the RayoVac rechargeable AA and AAA alkaline and many of the AA and AAA leak" The Rayovacs reviewed in the article ARE NOT the same alkalines you are trying to recharge at home. They are not Alkalines at all. read the article...

Comment #13

The Maha C204 charger appears to run very hot (batteries included). Users report that the Lightning Pack 4000N from runs cool and is also safe and ver fast. Comments? P.S. - Disclaimer: I have not used either charger...
