Sanyo’s eneloop batteries have been around for a while. People seem to like them when it comes to powering our various toys and gadgets. And now Sanyo is offering some new AA and AAA eneloop rechargeable batteries that will give you 500 more charges compared to the previous versions.

They are already charged and ready to go in the packaging. The company claims that they can maintain about 75% of their charge for up to three years and they are capable of up to 1,500 charge cycles. Perfect for Christmas time.

Many devices have moved away from AA and AAA batteries in favor of lithium-ion rechargeable batteries. But for things like TV remotes, the use of AA and AAA batteries are still the norm. We have rechargeable versions of these batteries, but sadly most people still rely on the standard one use versions and throw them away.

Brother has an alternative for low-power devices. A new Vibration-power Generating battery (VpGB) has been created which can be produced in both AA and AAA sizes. It does not contain a certain amount of energy which gets discharged and then becomes useless though. Instead, shaking the battery generates power which can then be used immediately.

Mophie’s juice pack air external case added some battery life to the iPhone, but it also makes your iPhone chubby. Now Mophie is introducing a line of external juice packs that pop into your device using a retractable dock connector.

The smallest will be the $40 1,000mAh juice pack reserve, then the $60 1,500mAh boost. Both are compatible with the iPod and iPhone and also offer “super-bright” LED flashlights. Lastly there’s the juice pack power station, which hasn’t been given a price or mAh rating, but will be compatible with the iPad.

If we can harness the power of childhood energy, especially those who play jump rope, we could do very well. This concept aims to take that jump roping energy and make it useful. It’s called the E-Rope and can generate power to charge a pair of AA batteries in each handle.

According to the designer, 20 minutes of jumping would fully charge all four AA batteries. Not sure if I believe that, but anything that promotes exercise and gives you charged batteries is a good thing.

This interesting concept will let you know visually when your batteries are low. Designer Mac Funamizu came up with the Hungry Batteries concept that has the batteries physically slim down more as they hold less charge.

Great idea, but it’s cheaper to just include one of those strips that can tell how much juice is left. If our gadgets also shrank, this would be great. No idea what they are made of or how long they would last.

This was an April Fools joke. Looks like many of you fell for it too. Silly fools. Okay, they got me too. Don’t you hate April 1st?
Expecting some replacable batteries in Microsoft’s Windows Phone 7 handsets? Don’t. Microsoft is disallowing user-replaceable batteries. And why not? Apple already does this and sales are just fine. So they are following suit.

It’s annoying, but the end result is apparently that it helps in creating a better looking handset. So if you were hoping for a phone that is the opposite of Apple’s, forget it. How do you feel about the whole swappable/non-swappable battery issue?

Panasonic is always looking to improve the life of their batteries and so they have just announced a new battery that lasts 30% longer than today’s lithium ion batteries. Instead of a graphite anode, the new rechargeable lithium ion batteries will use an anode made of silicon alloy. Panasonic even claims that after 500 charge/discharge cycles, the batteries will still retain 80% of their capacity.

That’s pretty huge when it comes to battery life. Aimed specifically at laptops, Panasonic says that the new battery technology will be produced in volume starting in 2012.

Duracell recently introduced its new Ultra Advanced battery that lets consumers know exactly how much power is available in each battery, eliminating the need to guess. The battery comes with Powercheck, which is a gauge on the battery that can be activated by pressing two white dots on the cell.

The Ultra Advanced with Powercheck will make their debut at Costco and some other major retailers in December. There’s a small additional cost compared to regular CopperTop batteries though, as you might expect.

We’re used to seeing our gadgets come in a variety of colors, but rechargeable batteries are generally dull and boring. Not anymore. Sanyo’s latest Eneloop Tone batteries introduce bright colors that they hope will entice you to buy some.

Sanyo’s Eneloop batteries are capable of being charged about 1500 times, and are sold already charged up without losing much of their original charge by the time they get to you.

Sanyo’s line of Eneloop batteries are as green a battery as you will find and they have some more improvements to make them even more Earth friendly. These newly upgraded Eneloops can be recharged around 1,500 times, which is said to be a new record for the industry.

The batteries come pre-charged from the factory using clean energy from renewable solar power. If we had to guess, we would say that the other big names in batteries are watching very closely indeed.

Energizer is really onto something with their Energi To Go gear. A few weeks ago we told you about their new XPAL battery chargers. Well, here’s another highly convenient product.

This USB clip will clip onto your DSLR and camcorder batteries and charge them up via USB. So what we have here is a much more portable DSLR battery charger. Nothing on price, but we should see it soon. We’re hoping the price is as convenient as the clip itself.

Need to add some geek to your diet? The folks at Antrepo Design Industry can help. These “Salt & Pepper Cell” shakers are shaped like D batteries, but they don’t hold energy. Instead they hold salt and pepper. The Cells have a strip that will show you when they need to be “recharged” with seasoning.

They’re made out of stainless steel and perfect for your geek dinners. You can get either a red and blue set, or black and white. Sadly, they aren’t for sale yet though. Antrepo is looking for a manufacturer. Let’s hope they find one. These are too cool.

Our favorite batteries are back. We’ve missed them. What other batteries are powered by your pee? Only Nopopo. As far as we know. We’ve missed you Nopopo. Our urine feels wasted without ye. But no more. This compact LED lantern will be equipped with a NoPoPo battery that doesn’t require a power outlet to juice up. It’s powered by water. Failing that, it will gladly accept your urine and give you power.

Sadly, the NoPoPo battery has been rated at just 500mAh and has a recharge capability of just four times, making this Wiz-powered lantern only good for emergency use.

A few weeks ago HP recalled 70,000 laptop batteries, but they aren’t done yet. They are recalling another 15,000 batteries sold in China. There aren’t any reports of actual fire or flames this time, but the batteries are prone to overheating, and can pose a fire hazard.

At the moment, details about the models affected are scarce, but the batteries were used in laptops manufactured between late 2007 and early 2008, and include models sold under the HP Pavilion and Compaq Presario brands.

I’m sure everyone’s heard of this, the good ol’ Sound Activated LED Equalizer T-shirt. For those that have are out of the loop (don’t worry, it happens to us all sometimes), all you have to do is put this on your body, and music makes it lose control. Well, pending that you have 4 “AAA” batteries, that is.
This shirt is not for doing homework in, though. Unless by “homework” you mean gettin’ super duper crunk. The LEDs on the panel respond to particular frequencies (primarily bass hits), so it’s not exactly the most versatile equalizer. But I think that feature makes it more interesting, as when there are dramatic pauses in percussion, they are matched by the LEDs on the shirt. It’s hard to find this shirt for under 20-30 bucks, so I hope you appreciate that today Dillyeo is offering it for 15$, after shipping.
