I have some Imedion 2300s in addition to my eneloops and the C9000.  I've also found them to be high quality cells.

Welcome to BLF!

You or Keith have a good source for Imedion cells? I'll try them out.

From my previous research, Thomas Distributing seems to be one of the better places to purchase in the US.  Unfortunately, shipping costs make it less practical for me in Oz.

They currently have a 16pack for $41.97 but I'm sure there are other quantities as well.  http://www.thomasdistributing.com/16-Pack-Maha-Imedion-2400-AA-Low-Disch...

Apparently if you order over $75, US shipping is free so you might be able to ask around if any of your mates need batteries to bump up your order quantity.

(FYI, the same 16 cells here would cost me about $78 delivered from a local seller.  Sucks!)

 

Other bargain hunters can probably steer you to Amazon, Adorama or Ebay deals but I doubt you can go too far wrong with Eneloops or Imedions from TD.

I bought some of those yellow ones for a bike light, which then left me stranded in the middle of the woods at night. After I tested them, they came out around 700mAh like yours and I got a full refund. I really can’t explain my total lapse of judgement, live’n‘learn I guess. Have a bunch of Tenergy LSD AAs now – I haven’t tested capacity but they last for ages and don’t noticeably self-discharge.

I also bought a couple of Uniquefire 2500mAh 18650s off eBay for $hits’n‘giggles – massive voltage sag @1A and ~800mAh capacity. Got my money back on those too. I even pulled one apart after soaking it in salty water for a couple of days and it looked like a real battery (no cell within a cell).

Moral of the story is… don’t buy non-brand batteries off eBay!

I see mention here that a test was done at 500mAh on these batteries but perhaps it should be kept in mind that this is a very high discharge rate for continuous discharge. It’s likely to cause some internal heating and would lower the capacity with the already high internal impedance (relatively) of Ni-MH cells. If you want this sort of discharge rate out of an AA size battery, your better at looking at Ni-Cad batteries which have a very low internal impedance. Sadly, it’s not possible to make Li-Ion batteries which could be used in place of 1.5V cells as these have a low internal impedance and a high storage density. I guess we have to wait till appliance manufacturers catch up now there is a ready supply of 3.7V cells with high capacity and relatively low price. I chose my torch based on this as I can get something like 24h continuous use on a single charge and the batteries are just a few $ on eBay.

500 mah is not very much for AAs, my eneloops can do 5 amps. 500 mah is not even .25c.

You can start a car on Ni-Cads, just you try that on your eneloops, it’s just a matter of what your using your batteries for. Bragging that my batteries can do 5A is great, but just what are you using them for that and, more importantly, how long do they last at that drain. I bet the capacity will not be the same at 5A than 5mA or 500mA… If you have an item that only uses a drain current of 50mA, perhaps some of these other batteries will show greater capacity at this rate (this is expected behaviour).

I agree that in high drain devices, like cameras, the batteries you mention are King but these may be an expensive luxury for low drain devices.

I have some of those and with a 150 mah discharge it lasted around 3 hours. Eneloops can do 10 amp discharges with a very good capacity. (Around 1500 mah) Also nicads aren't LSD.

So I just got myself one of them fancy battery chargers, a Triton Jr

Seems it can cycle batteries – discharge then recharge, and measure how much comes in/goes out.

Fascinating…. I’m looking forward to doing some tests on various rechargables I have!

LSD is a good thing. It means low self discharge. I’m not sure of the exact figures for eneloops but perhaps someone else can chime in Smile

To be fair to eneloop competitors, the batteries tested in this thread are not a comparison to any decent NiMH. This thread is not saying buy eneloops!

Before you think that eneloops are the only cells worth buying you really need to try the following:

Turnigy
GP
Vapex Instant

I own Turnigy , GP , and Vapex  ...

I have over a year now had several Turnigy AA "FAIL"  

No Eneloop has failed as yet , neither have my GP , and my Vapex are very old and still going ..

 

I tried ordering more AA ( junk ) , hmmm , last attempt to get a sample batch = failure ...

Seller did not want to co operate ?

The low mode should be lower.

I've driven hundreds of other batteries over the last 20+ years ..I was trying to show some old sanyos I bought probably 20 years ago . 1200mah nimh AA dark green rebadged sanyo white tops for a company named bt&t controls  I bought about 20 AA's and the next year at this electronics show all that could be had were sort of a lime green 1300mah cell I bought 50 of them AA and AAA's and everyone of those are dead , every energizer / rayovac kodak I've bought since then are all dead time and time again it's been sanyos  that are still kicking .Some of these batteries don't last a year .Buying anything but eneloops or rebadged sanyos is just wasting your money .  duraloops on sale were less than a buck  .Thats not rolls royce prices . They are always on sale and worth stocking up on.

Thanks for the valuable test man. Much appreciated. Less than 3x capacity than claimed.

Never ever forget and forgive. Niwal**er new kid on the block trying to act tough.

I have several non-sanyo cells that are still in A1 condition after 5 years. You seem to be talking about “lime green” 1300mAh cells vs old Sanyos – hardly a universally conclusive result in Sanyo’s favour… no offense but I think you need to take a little adventure and try some other brands, those 1300mAh days are long gone.

I have the same generic yellow cells but in AAA, and same generic cells but blue in AA.

Capacity is low but its more than enough for low power use : remotes,LED clocks and they are of-course the cheapest.

The PowerEx cells I got with my charger are rated at 2700 mAh and test at 2600. The Duraloops I got at Target were 1900. The black top Chinese Duracells tested a little higher at about 2000. I know with LSD cells you sacrifice some capacity, but I think the point is that there are other cells that can be good. The question is, do you want to stick with what you know, or take a chance?

2 x AA GP recykos, and 4 x AA Eneloops. Now, I thought the GP batts were pretty good, but the camera spat them out before I could take a shot.

I thought I should comment that my experience differs, and if I recall correctly, did not HKJ test the Recyko’s?

Anyway, I have had very good results from my GP AA and AAA Recyko batteries in both flash units and my SPark SD52 headlamp, as I also have Eneloops, I can say they are almost the same except the GP’s give me about 10% more run time.

If you are tempted to not consider GP due to heyho’s ad hoc comment, I’d suggest you do more research before you potentially talk yourself out of better value for your dollar.
