The Great Battery Shootout Link

This is a great review for sorting out which NiMH battery actuall is the longest running, independent of the claims that manufacturers make about how many mAh they pack into them!!! This thorough review really shows how good and bad these batteries are, and which one's are worth the money spent on them!!!

This is why i posted it, Because i have been through my share of Junk NI-MH Batteries Most from Radio shack. The New ones thay cary that are green in color are Total Junk and Even the AA types only last a few Mo before thay go from 1600 MAH down to about 500 MAH. I have never had any battery that bad yet. and all 9 volt rechargables are junk Except some of the Old Ni-Cad GE Brand

Oh I love this. There aren't many choices here in Canada - I haven't heard about 2/3 of those brands - but those "Energizers" that are in top-3 are available in any local London Drugs store at a good price. I even have two at home... sweet. Thanks ppl!

The Energizers work great both the Old ones with the Green Label and the New ones with the Blue label. The Old Energizers in the Yellow label are not so good but those are Ni-Cads.

Yeah, I have the 1600mAh ones but I might want to upgrade now. I need 10, and I need lots of capacity. My charger takes 12 hours to charge or even more though and that's tough, besides I need 3 of them for 10 batteries...

One option is to get Maxim chip from Digikey and build your own charger. Then you can charge whole bunch of cells in series (max of 12 or even 16?), and the chips have dual cycles - first fast and later trickle top-off if I remember well. Shouldn't be too hard. Apheared used to make his own chargers with these chips.

I can't recall the blue colored ones, but I'm sure I've seen the ones labelled 1850mAh...

Most, but not all. I've had very good results with the Plainview from Thomas Distributing.

If you want some great NiMh batteries for super cheap, check out this link here , you can find some great batteries. I'm pretty sure they're the same as the Sanyo batteries from the shootout, but these are rated at 1800mah. You can read some impressions here .

grancasa. thanks for the Link it is always nice to Know about low cost battery sources. I can't say how good the Batteries from them are since i have not tried them. I am cautious now days about the High capacity Batteries since i have Old 550 MAh Ni cads from GE that still put out and have got lots of use in flashlights. Ge later teamed up with Sanyo and again All those batteries still work great. Now Sanyo is alone but i still would think thay are as good as ever must try. My concern on the new 1600 & 1800 MAh is i have had three different brands go bunk after 6-8 Mo. this is unexceptable to me. The last batch of 1600 MAh AA's i got appear to be the same brand as the ones depicted on the link grancasa posted green plastic rap with black lettering. these i got from the C. Crane co. http://ccrane.com/batteries.asp. Note thay now have 1800MAh for $2.29 Ea. I have never had a problem ordering from them. real frendly people.

aos> The Max-712 is the chip myself and Apaheared used to charge 16 cells. However since i had this set up for fast charge and the batteries were mounted above the Amps board the fumes from the batteries venting coroded all the Contacts and solder joints in that Amp. if you do this mount batteries in there own separate box within the amp and set the chip for max charge to 5 hours rather than 1 hour to reduce venting. the batteries should be at the lowest point on the Chassis.

Hirsch> I have used the plainview and it is indeed one of the Best 9 volts available, However due to the small cells these can not be fast charged with the exception of one or two types. also if you need to draw anymore than 10-15 Ma on a consistent Basis the batteries will not last worth **** and i hate to have to buy new batteries every few Mo. My alternative to 9 volts is the AAA';s. I do use 9 volts in my pocket amp but that amp is battery frendly.

About the RadioShack batteries, with the green label, I agree that they are junk. Even their chargers aren't as great as I have originally thought some of them to be. Why does RadioShack charge $35 for an 8-cell smart charger that not only requires batteries to be charged in pairs, but actually has only one commonly shared charging circuit (that I found out simply by looking at the unit: The bay-selector switch is a giveaway that it uses only one charging circuit)?

By the way, I have a set of four RadioShack "gold label" 1500mAh NiMH batteries that are still going strong (well, they were at the time the highest-capacity NiMH AA rechargeables that could be easily purchased at stores - most other brands had only 1200 or 1300 mAh rated capacity at the time). On Consumer Reports' most recent test on NiMH rechargeabe AA batteries, they did a test between RadioShack 1500mAh batteries, Ray-O-Vac 1300mAh batteries and Energizer ACCU 1200mAh batteries. The Energizers back then performed worst of the three, and by a large margin, at that. (CR had charged the batteries in the charger that's the same brand as the batteries themselves, so much of the differences in the results is attributable to the chargers themselves. It appeared that the Energizer charger didn't charge batteries anywhere near as completely as those from the other battery brands tested in that report.)

Energizer has changed the label again for their NiMH batteries: The original Energizer ACCUs (rated at 1200mAh in the AA size or 600mAh in the AAA size) had a green-and-gold label. The next generation of Energizer NiMHs had a blue-and-gold label, and were rated at 1200mAh or 1600mAh in the AA size or 700mAh in the AAA size. The current Energizer NiMH label is green, black and silver in color - and AAs with that label come in 1700mAh (last year's version) - and now, 1850mAh (AAAs are now 750mAh). All Energizer NiMH AA and AAA batteries made recently are manufactured by Sanyo. (These label changes carry over into the C, D and 9V sizes - but the C and D size Energizer NiMHs are still the same archaic design as the first-generation ACCUs, with both the C and D sizes using the same actual 2200mAh cell in a larger-sized shell, and the 9V model is still of the same archaic 7.2V/battery design.)

The Old Radio shack gold label batteries i have no fault with except the 9 Volt. I still have some old 1200 & 1500 mAH AA cells going on five years old and still as good as new. All the New green ones are bad and i threw them away 6 mo on the oldest. The Charger i use is Hear http://ccrane.com/chargers.asp i use both the CHG at $49.95 and the Solar charger SBC at $14.95. the solar charger takes all day on AA 1800mAH. but the CHG is alot faster about 2 Hours. The C Crane co. is also a great place to get Rechargable batteries http://ccrane.com/nickel_metal_batts.asp

Actually this is a Canadian website and I have bought from them. http://www.onlybatteries.com/main.asp

I ordered my batteries from here: http://www.gadgetnerd.com/order.php

Great place to deal with.

edit: (its a canadian site)
