New Battery Technology

[SCPD]

I am wondering if anyone here on Radio Reference has used these new batteries made by Powergenix ? They are a new NiZn type technology.

They seem to be a real big hit in the photography industry for use in flashes.
You can check them out on YouTube.

I am not related to the company in any way .. just wondering if anyone has used them in their scanners etc.

Thanks ..

I've never used them, but they are nickel-based and means that they will more than likely suffer from "battery memory" problems. Yeah, I know almost all batteries go through this, but some fair far better than others like Lithium Ion (which really do not need any training).

Seems interesting, though (to be back to your question) in that they are cheap, 1.6v and recharge.

I wonder what the mV is rated at for those in the video?

NiMH batteries don't have memory problems.

You mean mah (capacity in milliamp hours) rating?

NiMH batteries don't have memory problems.

Yeah, they only suffer voltage depletion. I guess it's not the same.

Actually, I meant mAh, but I was replying from my phone at the time and it didn't come out the way I wanted. I blame Swype for not knowing what I wanted.

I think you are talking about "self-discharge". All NiMH batteries do not have the same level of self-discharge. I find the LOWER the mah rating, generally, the lower the self-discharge.

For example; all brand of batteries I tried that were 2500 or more mah had a high self-discharge. The Sanyo Eneloops I am using, 2000 mah, have a relatively low self-discharge rate. I also have some Chicago Electric 2000 mah that are better than the higher capacity batteries, but not as good as the Sanyos.

No, I am talking about "voltage depletion." That is where a battery will not deliver the same voltage over time, after several recharges. While not "technically" the same as battery memory, it is essentially a memory-like effect. So while they will still charge to full capacity, they will deliver less and less voltage over time.

The powergenix appear to be a big hit in the photo industry. They are able to be used in electronic flashes and perform better than just about anything out there.

The powergenix .. have to be used with a dedicated charger (which is usually purchased with the batteries). Apparently this is the newest technology in batteries.

It doesn't look like the powergenix are available widely yet .. so amazon.com is one of several places where you can get them.

Here is a test that is on YouTube .. testing the powergenix versus others. http://www.youtube.com/watch?v=v54CN6pB2uA&feature=related

Personally .. I use Sanyo Eneloop as I like to know that when I want to use my scanner that the batteries are more than likely going to perform.

Damn. Time for a new phone, dude. Every time you type voltage depression, it comes out as voltage depletion.

Har har?

They are two terms for the same thing.

In case you were curious.

Well, I wouldn't rely too much one one misguided FAQ. The phenomenon does not match well with the definition of "depletion". I would go with more authoritative sources: Duracell PROCELL: Design Tools: Glossary

Oh, I'm sorry... you are right, everyone else is wrong. Only your sources are viable and "authoritative" when it comes to something like this.

Still, they are both terms used to describe the same thing. Regardless of how much you like one term better, that does not change the fact that both are used.
