Preorder The Roost: A 9V That Gives Smoke Detectors Notifications

Back in January we got our first hands-on with the Roost at CES, but anyone who’s ever used a 9V battery is already familiar with the product. The only difference is that this 9V includes built-in Wi-Fi to give your standard smoke detector the ability to send alerts to your smartphone.


You Can Jump Start Your Car With A Dozen AA Batteries

Although you should probably just keep a set of jump leads and a spare $20 in your car, it turns out there’s a non-conventional way to revive a dead battery, using a dozen AAs, a little soldering, and some firmly-crossed fingers.


Tesla's Battery Gigafactory Is Coming Along Nicely, Thanks

Video: Just like the massive Apple Campus 2, Tesla Motors’ US$1bn battery-building Gigafactory is under construction — out in the Fallout wastes Nevada desert, rather than in the heart of Silicon Valley — and the building process looks like it’s well under way. A drone enthusiast took the opportunity to take a look at the nascent plant, and filmed the entire thing in 4K.


Tesla Australia Is Bringing Fast Chargers To You With Destination Charging

The biggest concern about driving a Tesla on a giant, barren island at the bottom of the world is wondering where you’re going to charge it.

Four Easy Tips To Make Your Batteries Last Longer

Here are a few things you can do to make your lithium-ion (Li-ion) batteries last longer, whether they be used in an electric car, a large home installation – such as Tesla’s newly announced Powerwall – or in your portable device, such as a smartphone or laptop.


Tomorrow's Battery Technologies That Could Power Your Home

The recent announcement by Tesla of Powerwall, its new lithium-ion (Li-ion) based residential battery storage system, has caused quite a stir. It even raises the possibility of going off-the-grid, relying upon solar panels to generate electricity, and storing it with their own battery and using it on demand.

Yet the lithium-ion technology used by Tesla isn’t the only one on offer.


This Tiny Battery Could Make Small Chips Entirely Independent

While chips have gotten increasingly smaller, even low-power silicon usually uses off-chip power supplies because shrinking batteries down is difficult. This new super-small battery could finally put power supplies on the chip — and tiny computational systems anywhere you can imagine.
