Duracell’s “coppertop” batteries are engineered to be some of the most dependable in the world, and with a plethora of cool new gadgets out there this holiday season, you’re going to need a near endless supply of juice to power up and play. The problem is, good batteries can be expensive.

But not if you take advantage of this awesome offer from Cult of Android Deals. For a limited time only, you’ll pay less than half — just $52.99 — for 100 AA and 52 AAA batteries.

Researchers at Stamford University have developed new lithium-ion batteries that could triple the battery life of future smartphones. The new batteries have higher energy storage density than existing lithium-ion packs, allowing them to pack as much as three times more power inside the same space.

Every smartphone I purchase for my household has to have a few specific features, one of which is a removable battery. Lately, I’ve been concerned over the growing trend of OEMs locking up the backs of their devices and thus making the battery non-removable (at least without having to grab a screwdriver). I’m not sure what advantages, if any, having a non-removable battery provide, but I am certain of the advantages having a removable battery provide.

Laaaaaaaaaaadies and Gentlemen, welcome to Friday Night Fights, a new series of weekly deathmatches between two no-mercy brawlers who will fight to the death — or at least agree to disagree — about which is better: Apple or Google, iOS or Android?

After this week’s topic, someone’s going to be spitting teeth. Our question: Should The iPhone Allow You To Easily Swap In And Out Batteries? A lot of Android phones let you swap in and out batteries if you’re low on power, but Apple’s never done so. Is this just another example of Apple hardware oppression, or do they have a good reason?

In one corner, we have the 900 pound gorilla, Cult of Mac; in the opposite corner, wearing the green trunks, we have the plucky upstart, Cult of Android!

Place your bets, gentlemen! This is going be a bloody one.

If you own a 4G LTE device from Verizon then you already know all about battery drain. There are many ways to help improve your battery life on a 4G LTE device, but one of your best options, is to simply purchase an extended battery (if your device has one). It was the first thing I purchased alongside my Galaxy Nexus, and one accessory that I recommend to anyone looking for an extended battery life. Not too long ago, Verizon had the Galaxy Nexus extended battery on sale for 50% percent off, and we’re happy to report that this deal extends to all extended batteries available for Verizon’s 4G LTE devices.
