earthCell batteries are a new type of battery technology called low self-discharge nickel metal hydride (LSD NiMH). These are some of the best batteries on the market, and are far superior to the regular alkaline batteries that most people buy and throw away. (details below)

They will last longer than almost any battery you've ever used. Then, at the end of the battery's charge, all you do is put them in the prepaid earthCell mailer. When the mailer is full, you drop it in the mail, and we'll take care of them.

(He had me at the following statements..)

We want to clean up the battery industry. We are proud to offer superior batteries at a better price, along with the earthCell mailer for super-convenient recycling through us.

Zero waste. Better batteries. Less money. With your help in getting started, earthCell will transform the battery industry, for good.

I think Energizer & Duracell might not like this at all... tongue.gif

So the bunny doesn't keep going? That must be why I chose DURACELL!

Back to the topic... cool. Can we has now? Can we has cheap now? Now?

I remember back in the day always needing batteries... now I have loads of them and very little to do with them.

It always felt like Duracell lasted longer then any other battery I tried.
It's TURBO TIME!

I remember back in the day always needing batteries... now I have loads of them and very little to do with them.

Well I don't use batteries much per se, and they don't really make a lot of cameras that use AA batteries any more, which suxs hard...

But my kids use the heck out of batteries, a lot of gadgets still use them...

I wish they would make more tech that used AAA or AA batteries instead of other batteries...

The thing is with super lower powered devices, it's just best to use Solar Power any more...

That's what I want to invent a solar powered flash light... (I K33D / I kid!) biggrin.gif

Awesome, now my tv remote will last 3 years instead of 1!

... Not sure what else even uses batteries anymore. Great article non-the-less.

Can someone translate the numbers presented in that battery capacity chart to mAh ?

This type of Ni-MH batteries already exists and Duracell also makes them. I have two of them, they are rated at 2000 mAh, while their conventional Ni-MH batteries are rated at 2650 mAh, but have, of course a much higher discharge rate, which means that you can't store them for very long with their charge.

I also have a pair of Varta batteries that are rated slightly higher, at 2100 mAh; I bought both Duracell and Varta batteries last year (or was it two years ago ? Can't remember), and they work fine and can easily be recharged in a normal Ni-MH charger. I haven't checked the market again, maybe there are higher capacities by now. Edit: see post below. Yes there are.

Now here is what troubles me about this project:

How different are these earthCell batteries from the ones I mentioned ? What capacity do they have?

And this in their FAQ is what troubles me the most:
Quote:
Can earthCell batteries be recharged at home?

Yes. If you buy the right LSD NiMH charger, earthCell batteries can be charged at home. We're of the opinion that most people don't want to manage their own battery stock. We've designed earthCell to give this majority of the market an environmentally friendly option.


Isn't this a little of a lazy mentality ? If you buy the charger - is a different charger needed than the current ones for Ni-MH ? (Edit: no, it isn't, you can charge them with your current Ni-MH charger, see my posts below), you can recharge them hundreds of times yourself. After the batteries have reached their useful cycle, then yes, mail them to the company for recycling. And this ties in with the first FAQ:
Quote:
Why are earthCells the LSD NiMH chemistry?

The Low Self Discharge Nickel Metal Hydride chemistry is a relatively new battery chemistry that is superior from a technical and an environmental perspective. These batteries will serve you better than alkaline batteries (the common household battery). Further, when we receive them, we can revitalize them with our specialized infrastructure hundreds of times, vastly decreasing the quantity of materials that need to be mined, reformed, and eventually recycled, and all of the associated environmental costs in doing so.

The added expense to us of using this superior technology is worth it. We believe we can transform the battery industry from a very wasteful, polluting one into a closed, zero-waste industry. All you have to do is make sure that your used batteries make it in the earthCell mailer and get back to us. We'll take it from there!

What does this mean ? "Revitalize them" ? They don't use the word "recycle", and it seems they are not using the word "recharge" on purpose.

So, this is basically a "We are selling you rechargeable batteries but we think that you are too lazy to recharge them yourself, so you can send them to us, we'll recharge them and sell them to someone else, perhaps with a new wrapping if the current one is getting too old. So, in the end we make money off your laziness."

Jues went to Wikipedia, and it seems the batteries I have are exactly what I'm talking about. Varta released a higher capacity version last year, at more or less 2300 mAh:
Quote:
Developments in 2011

Varta (USA: Rayovac) and Ansmann increased their LSD NiMH batteries' capacity to roughly 2300 mAh. Sanyo introduced a new version of its Eneloop batteries with increased capacity and life expectancy. The "Eneloop plus" incorporates a PTC thermistor that disconnects the power if the battery overheats, in order to make it safe for use in toys for small children.

So, these batteries can be recharged with normal Ni-MH chargers that people already have, there is no special charger for this type of batteries. This earthCell thing is smelling more and more like a scam, really.

As a side note, in Europe we already have a recycle program for all kinds of batteries, you put them in a container that is usually put next to the glass, paper, and plastics containers.

Just found this article with all makes of these types of batteries that are or were for sale (even Kodak made / makes them): http://mark-lawton.com/pre-charged-rechargeable-batteries/


So, this seems more and more like an elaborate way of saying they are expecting people to not recharge them, send them back after only one discharge cycle, and then sell them back. No wonder they are selling them slightly cheaper. What they forgot to tell specifically is:

- you don't need a special type of charger for these batteries - Duracell and Varta even label them as Ni-MH batteries (just checked with mine), not LSD Ni-MH, normal Ni-MH chargers work, so their FAQ is deceiving;

- other manufacturers make this type of battery, including Duracell, but they compared their battery to Alkaline batteries, forgetting to tell that you can recharge the Duracell LSD NiMH ones and theirs with the same charger;

- if they have proper recyclying facilities or only recharging facilities;

- what will they do when they actually have to recycle them;

- their business model doesn't work if people actually recharge them at home and send them back only when they are dead.
