The downside of these batteries is that they're not rechargeable, but they're still smaller than other standard batteries and will be great for newer, tinier gadgets. [Tech On via Engadget]

This DSLR battery clip charges via a special USB source (like Energizer's own portable battery pack, which has a higher voltage than standard USB) and clamps on to "any" digital camera or camcorder battery. The compatibility list is probably high, but we're unsure if any actually means any, so check out the site before buying. The entire Energi To Go line will be available next month.

The first new entries, two form-fitting, rubberized AP Charger battery packs for the iPhone, had me thinking of Incase Power Slider.

They're not as eye-catching as the Incase, but they're not as expensive, either. It's $50 for the AP1000 and $80 for the beefier, longer-lasting AP1500. Weigh your options, battery pack wants and desires accordingly. Also, in the case of the AP1500, Energizer promises to double the battery life of a typical iPhone charge. Updated: As some commenters have noted, and I'm inclined to agree with, that branding front and center is fugly at best. Definitely not subtle.

In the aforementioned solar power category comes the SP1000 and SP2000, for $50 and $100, respectively. Boasting 500 charges each, these solar cells include a set of tips so that you can charge all manner of GPS devices, MP3 players and cellphones out in the wilds of suburbia. Or camping in the woods too, if that's your thing. More tips are available online, should the included six not meet your needs. The SP line even charges via indoor light sources, although not as quickly as the advertised 6-hour charge time in direct sunlight.

In all, there will be about 10 new additions to this line of battery packs and chargers coming in June, Energizer tells us, courtesy a new partnership with XPAL Power. Not much else to say on XPAL save a brief mention in our glorious Gadget Deals of the Day series.

The Energizer Hard Case Tactical Flashlight 2AA features a 70-lumen white LED, along with four additional LEDs including red, blue, green and infrared—a selection of fine lighting choices for incognito map reading or simply an impromptu infiltration disco.

Droppable from 15 feet and including a swiveling head with a range of motion of nearly 180 degrees, it's pretty neat for a flashlight, but it'll set you back $125. And you can call me cheap, but I just don't assassinate world leaders in the dead of night often enough to justify the purchase. [Popular Mechanics via Newlaunches]

If any of the consoles were in need of a wireless charging solution for their controllers, it was the Wii. All of the suggested Wiimote safety accessories make the thing such a hassle to try and keep powered. Now, it's just a matter of casually placing it on a stand and letting the charger go to work. It will be in stores in May for $50. [IGN]

The Energizer AA batteries are rated at 2200 mAh and the Duracells at 2000 mAh (that's milliampere-hours, a measurement of energy charge). But the Duracells last a lot longer.

I tested using an ICON LED flashlight, this solid aluminum model with high and low settings—the high setting killing a standard battery in about 3 hours. Through several trials using different cells, the Energizer lasted 2 to 3.5 hours, while the Duracells took anywhere from 5 to 6.5 hours to drain. Not an insignificant discrepancy, and contrary to the respective charge ratings on each.

The Duracell family of rechargeable batteries also come precharged out of the package, so that's very convenient. They've also got USB ports for charging USB gadgets. Both companies offer car and 15 minute chargers. The Duracell Mobile charger is my favorite simply because it has a car adapter and a wall adapter, and can charge 4 AA batteries or any USB device from those sources. (It does not do 15 minute charges, however, but I'd rather buy extras and have them ready to go.) The only real drawback is that it can't charge D cells and 9V batteries like the giant sized Energizer family charger can. Both kinds of batteries are NiMH. Duracell claims their batteries will hold their charge for a year in storage, while Energizer claims only 6 months.

Frills aside, the bottom line here is battery life, and Duracell has a lot more of it than Energizer.

The heart of the gadget is a simple battery charger, intended for regular rechargeable AA and AAA batteries and primarily powered by an AC jack and assisted by a flip-out solar panel. A USB port is capable of providing power to a connected gadget, which allows the Solar Charger to also act as a sort of extended battery for virtually any USB-powered device, iPods included.

By choosing cheap semi-disposable rechargeable batteries as the guts of the device, Energizer will reportedly be able to keep the price down at a reasonable $50, 2 AAs included. Considering additional features like weatherproofing and a rotating solar panel, the Solar Charger could turn out to be a cheap, viable alternative to the endless droves of device-specific battery extenders and pricey solar chargers that are floating around for the time being. The official announcement is expected at CES 2009. [GoodCleanTech via CleanTechnica]

It's called Zinc Air Prismatic and the company promises that it will offer 3x the battery life of a similarly sized alkaline or lithium ion competitor—or the "highest energy density of any consumer portable power solution."

The battery will utilize zinc-air reactions (zinc oxidizes when introduced to oxygen), a known method to produce inexpensive, powerful batteries—their most famous use probably being hearing aids. (Why exactly we haven't seen bigger versions on store shelves already is beyond us—anyone in the audience know more about manufacturing the tech?)

Unfortunately, zinc-air batteries are not rechargeable. So it's doubtful that Energizer Zinc Air Prismatic will be either. [Energizer]

Household Gamers: Keep the Remotes Handy and Ready to Go with Energizer(R) Power & Play Charging Systems

While disposable batteries are an appropriate solution for many gamers and households, some - especially heavy battery users - prefer to rely on a rechargeable option. That's why - for active gamers - Energizer is now offering Energizer(R) Power & Play charging systems designed specifically for Wii(R) by Nintendo(R), Microsoft(R) XBox 360(R) and Sony(R) PlayStation 3(R) wireless controllers.

The Energizer(R) Power & Play charging system for Wii(R) by Nintendo(R) remotes, which retails for a suggested price of $39.99, comes with rechargeable batteries, replacement battery doors and a charging station. Replacement rechargeable batteries and covers are also available for $10.99. The rechargeable battery pack for the Wii(R) Fit by Nintendo(R) is equipped with an audible and LED low-battery indicator and has a suggested retail price of $29.99.

The Energizer(R) Power & Play charging systems for the Microsoft(R) XBox 360(R) and the Sony PlayStation 3(R) include a charging cradle and A/C powercord and have a suggested retail price of $29.99. Additional charging cables are available for $12.99 for the XBox 360(R) and $9.99 for the PlayStation 3(R).

Sleek, convenient and easy to use, all of the new Energizer(R) Power & Play charging systems will be available in stores this month, just in time for the busy holiday season. Created through a licensing agreement with Performance Designed Products (PDP), the new Energizer(R) Power & Play charging systems mark the first time that Energizer has partnered with a manufacturer in the gaming arena.

"With the popularity of gaming, we wanted to give gamers two viable solutions to power their favorite wireless controllers," said Laakko. "Whether using Energizer(R) Advanced Lithium or our new Energizer(R) Power & Play gaming charging systems, gamers using Energizer products can rest assured that their fun will last and last."

Unlike many of the backup lighting solutions out there, some of the 7 available products in the On Demand lineup are built for everyday usage. That, combined with the wireless factor would make them an attractive choice. Plus, in an emergency situation, the lights can be removed and utilized as a flashlight. No pricing information has been released, but the devices will be available in Target starting this month with a full release slated for the summer. [Energizer via PR Newswire via Gadget Review]

The Energi To Go portable battery chargers from Energizer have just been updated to support the latest iPods. The chargers, which are powered by Energizer e2 Lithium AA batteries, can supply the new nano with 46 hours of battery and the new classic with 32 hours. Seeing as the iPod connector is pretty much standard over all the recent iPods, including the iPhone, it should be able to charge pretty much every Apple player you own. [Energizer via Mobile Whack]

Energizer has two widgets, one for Macs and one for Windows, that let you monitor the charge as it's happening—in real time. It's like a mini-episode of 24 happening in your own machine, except instead of bombs getting found, you're making sure you have enough batteries for your Wiimote. Price is still $14. – Jason Chen
