I wonder if this is a fake. This reminds me of the story about the rechargeable Energizer D cell battery, a product that’s actually less than you might think.

I question the energizer thing. According to the energizer data sheet, the D cell has a capacity of 20,500 mah, not 2,500 mah as stated on this web page. Also, he says that energizer D cells are $12, the actual price is $1.47 in single piece quantities at Digi Key. I smell either an outright scam, or someone trying to sell “Powerex “D” rechargeable batteries”.
That said, I have seen counterfit parts, most vendors are good about accepting return of counterfit parts.

Go to data.energizer.com and look up Product Group NiMH Rechargable. The D is listed as 2500mAh. I have these batteries and they don’t weigh much more than the AAs.
Umm, it’s called electrical tape because it DOESN’T conduct electricity.
This is my mistake as I was thinking Alkeline batteries, not NiMH.
Here are some comparisons on D cell NiMH
Panasonic:
8250mah or 6500mah
Energizer:
2500mah
Radio Shack also had and may still have rechargable “D” batteries that seem hollow ! Caveat Emptor !
Yeah #4 we know that. Did you watch the video?
The link is nothing but a sales pitch from an illiterate buffoon trying to sell his $15 batteries.
Hey, I can print 25,000,000 mAh on my batteries… it means nothing. Let’s see him cut one open.
That device may be designed that way to dissipate heat.
Intentionally building shoddy, poor or underperforming products in order to screw people is fraud against the customer and the active destruction of the environment. It is a crime with real victims, and should be treated as such.
@LES (#2):
Mark Erickson’s the shit!!!
Although I question the whole thing, that capacitor may have been customed up to fit a particular form factor in an older device.
They could also fill the outer case with oil – for heat dissipation or higher voltage ratings. Often newer components can do the same job in a smaller package….
Anybody’s guess, really. However if the things aren’t overpriced and work per spec, who cares?
Most “C” rechargeables, btw, are made like the capactitor. A slightly smaller cell is packaged in an outer skin for size reasons. Nobody seems to care.

Stu.
Its either a fake pic or a fake cap. Look at the labels on the outside. The outer skin says 6800uF, the inner one says 2200uF.
50 volts on the outside and 35 volts on the inside is likely to get prompt attention by someone using this part.
You get want you pay for. You pay shit, you get shit. Of course sometimes you pay lots and get shit.
#2 Les,
Is that Erickson guy supposed to be for real?
besides the electrical tape thing it is a bad idea (fire/explosion hazard?) to try and recharge non-rechargeables.
Uh, folks – these are capacitors not batteries. In this case they may have put the larger can over it for shielding. No way would anyone try to pass off a 2200uF 35VDC cap for a 6800uF 50VDC cap. Unless of course they were building some piece of crap for Microsoft.
Chickety china da chinese chicken!!!
Have a drumstick and your brain starts Cricken!
Open the blue one, might find a surface mount tant
#16 TatooYou,
If you watch all of his videos you will see that they are all satire, but he makes no disclaimer anywhere to indicate that they are.
I think he is hilarious, but to some it may seem like he is serious.
I was once the quickest path to ground for 3 cans hooked in series. 450v 100mf that hadn’t been discharged.
Blew a chunk clean out my little finger and made my arm numb up to my elbow.
Since then I’ve never forgotten to discharge those sucker before working on electronics.
A hot CRT is like a baseball bat across the kidneys.
I don’t think I want to do that again.
35V in a 50V circuit? At least it does not have an epoxy case. They are very hard on the nerves when they blow.
Fun to set up a co worker with one.
I’m thinking ‘fake’. Rubycon is a good-quality brand used by most of the majors – so putting one in a phony outer can – WTF?? Where’s the profit??
If the outer can said ‘Rubycon’ and there was a cheap No-Namo on the inside, that would make sense, but the other way around? It’s like selling a bogus watch that said Timex on the outside, but had a Rolex movement inside… no sense to it.
Sorry Les, I thought you were a dumb dumb. The part I missed was in your second post “Along the same line:”. Some people are dumb dumbs and I honestly thought you were one too.
# 20 Thanks Les, i went back and viewed the band-aids ski googles video, I didn’t have a clue, then I watched the Wi-fi cell phone video and realized he was kidding around, very dry humor!
At one time there actually were batteries made by (or for) Radio Shack, which were AAs inside C and D cell size cases. And if I remember correctly, they were only the rechargables. I quess RS figured that since you’d recharge them. It didn’t matter how long they held a charge. And they could offer their D cells for much cheaper than other brands. Frankly, I’ve never found rechargables to be much good for anything but flashlights. Standard C and D cell rechargables run down too fast for motorized devices and toys. You need those extra large cell packages, for RC model cars and such.
#26: NiMH batteries are much better for digital cameras than alkalines. Something about the way they discharge lets them last longer in service.
OTOH NiCds basically suck. Gel cells are pretty good, though.
I’ve had great luck recharging plain old alkaline batteries (Duracell, from 9V to D’s) with a Ray-o-Vac charger. The blurb for the charger does not state it will charge alkalines, but there is no warning against doing so either. I usually get about 10 charges per battery.
Not bad for a $35 device. I’d be glad to post a link for the charger if anyone is interested.
#24 KevinL,
no problem
I buy my batteries from http://www.nimhbattery.com/index.htm
Very good service!
They got 12,000mAh D’s
6000mAh C’s
2900mAh AA’s which I use for my electronics, they do good on LED based flashlights as well.
looking for some Li-ion on standard size batteries.
