The External Battery Round-Up Review

Posted by Jason Dunn in "Laptop Thoughts Articles & Resources" @ 07:45 PM

"Shopping for a notebook involves a delicate balance between battery life, performance, usability, and price. No two users share the exact same criteria for what they consider the right blend. That's why we try to evaluate mobile platforms based on their perceived strengths. Take last year's Netbook Buyer's Guide as an example. We considered the fact that some buyers are willing to spend more for battery life and forgo a bit of performance. Others are willing to pay an extra $100 or $150 to get both. Another group cares more about usability. The list of ways to break even this one specific market into tiny pieces goes on and on."

Looking to get more run-time out of your laptop or tablet? These external batteries are your ticket - though all are definitely not created equal. I've been a fan of external batteries for years, though I've always ran into the same problem: I'd get an external battery, it would work great with my current laptop, then I'd upgrade the laptop and the external battery would support my new laptop. The myriad of changing tips and the weird incompatibilities introduced by the laptop OEMs when it comes to third-party power solutions - my Dell Vostro V13 won't charge from my iGo Juice for instance unless it's in sleep mode, and Apple is infamous for making life hard on the people who make these products - can make for a lot of headaches.

On the plus side, when you have a combo designed to work together, it can be handy - I have a Tekkeon MP3750 that was sent to me for review, and I've used it with my Dell V13 with great success. Carrying an external battery can add to your overall travel weight, but if you need to work for long periods on your laptop or tablet device, they can be worth their weight in gold!

Battery Recharging Myth-Busting: Don't Completely Drain Your LiIon Batteries

Posted by Jason Dunn in "Laptop Thoughts Articles & Resources" @ 01:30 PM

"Battery-centric web site Battery University explains the real relationship behind battery life and charging. Lithium-ion batteries-the batteries present in most modern smartphones and laptops-don't need to be fully discharged every once in a while to retain battery life, as many of us have been told. In fact, it's quite the opposite..."

Over the years, I'm sure we've all heard a lot of crazy battery advice: don't recharge your phone/laptop/MP3 player until it's completely dead; don't charge it too often; when you're not using it, take out the battery, etc. Much like telling someone they need to defrag their Wi-Fi connection, some of these "tips" just aren't true. This article gives you some important tips about how to maximize the battery life on your portable device.

Boston Power Batteries Broadly Available...via Generic Third-Party Batteries?

Posted by Jason Dunn in "Digital Home Talk" @ 02:00 PM

It seems like an eternity ago when I was at the first - and so far, only CNTRSTG event - and I heard Dr. Christine Lampe-Önnerud talk about Boston Power's battery technology. Go check out that article for details on why Boston Power's battery technology sounded so promising; I've been waiting since then to see Boston Power batteries show up from Dell, HP, or pretty much anyone else...and for the most part, I've seen nothing. So imagine my surprise when I was looking for a battery for an old Toshiba Satellite M50 and saw that the Dr. Battery site had Boston Power's Sonata batteries available for hundreds of laptops! The basic benefits are 1000+ charging cycles before a reduction in performance is seen, a three year warranty, and a performance cycle of 3-5 years. The latter is important for those laptops that stay plugged in most of the time and don't get a lot of charging cycles.

I'd absolutely pay more for Sonata batteries on my next Dell or HP laptop - so why aren't the big guys giving me this option? Is the only way to get this technology from Dr. Battery? Something seems quite wrong about that...

Valence Technology Exits Mobile Battery Power Market

Posted by Jason Dunn in "Digital Home News" @ 01:00 AM

"Valence Technology Inc. (NASDAQ: VLNC) today announced that it will discontinue manufacture and sales of its N-Charge ® Power System on July 31, 2008, in line with the company’s previously stated strategy to focus on the large-format energy storage market. “Response to the N-Charge system has been positive,” said Bob Kanode, president and CEO of Valence. “However, our decision to discontinue the N-Charge product helps us to focus our resources more effectively on the large-format energy storage market where we expect to see significant growth opportunities.” Affected products are the VNC130 (1001153) and VNC65 (1001152) and associated accessories and peripherals."

If you read my review of the Valence N-Charge battery two years ago, you'll know that I thought very highly of the product - it was an amazingly powerful battery, giving me nearly 20 hours of total battery life with my little Fujitsu P7000 series laptop. The biggest problem with it was that Valance used a specific connector for each laptop, so once I stopped actively using my Futjisu laptop (it sits in our TV room now and doesn't leave my house), it essentially became useless to me. When you buy an expensive accessory (it cost $299 USD) you want to be able to use it for longer than your laptop lasts - and Valence had no adaptor for my Dell XPS M1330, so I was out of luck (you can read all about it in this article). It's really unfortunate, because a properly-done mobile battery is a powerful tool - yet I struggle to find one that really fits my needs. Valence evidently doesn't think they can get this right - is there anyone out there who can?
