suggestions for long-lasting battery

<p>i heard that toshiba has long-lastin battery...is that true? if not, can you give me suggestions for laptops that have good batteries?</p>

<p>Any laptop where you can get a 6 cell battery will last longer than a 4 cell or a 3 cell battery… a netbook with an Atom processor (designed for power efficiency) would be ideal if combined with such a battery. I happen to have that setup in my msi Wind, and let me tell you, the battery lasts *forever<a href=“well,%20okay,%20not%20literally%20but%20that%20was%20the%20impression%20I%20got%20when%20I%20first%20realized%20how%20many%20hours%20I%20could%20push%20out%20of%20this%20thing”>/i</a>.</p>

<p>Nuclear powered laptops last quite a while between charges.</p>

Yeah, I’d definitely go with a nuclear-powered laptop if I were you.</p>

<p>Hopefully there is no radiation issues while you use it on your lap.</p>

That won’t be a problem, as long as you wear one these suits while your operating the laptop <a href=“http://www.benthic.ca/data\reports\33\A%20bit%20bananas.jpg[/url]”>http://www.benthic.ca/data\reports\33\A%20bit%20bananas.jpg&lt;/a&gt;&lt;/p&gt;

<p>Also, make sure you DO NOT drop your laptop.</p>

<p>And whatever you do, do not use it in your lap, lest your future children become eligible to apply for entry into the X-Men.</p>

<p>Besides those things though, nuclear powered laptops are great!</p>

<p>LED backlights, as well as low-power CPUs (like Atoms or M-series ones, NOT the desktop models stuffed into laptops) tend to improve batter life by a drastic amount.</p>

11

<p>LED backlights also happen to be very hard to find as well as very expensive and probably not worth the extra 20 minutes of power you are going to squeeze out of the battery. Low power CPUs on the other hand is crucial for long battery life.</p>

12

<p>LED screens are becoming a lot easier to find.</p>

<p>and really each different model of computer will have a different battery life even ifthe components are almost identical…</p>

13

<p>Two different life questions for batteries:</p>

<p>1) How long will the battery power your computer between charges (run-time: how long until you have to recharge); and</p>

<p>2) How long until the batter no longer charges (have to replace the battery)</p>

<p>Figure out how much run-time you need, and get a batter that is rated to last twice that long.</p>

<p>Hard to know how long a battery will last you. I would guess the better brands will last longer, and don’t buy a used battery.</p>

<p>Run-time is just one factor when choosing a laptop. Not my most important criteria, unless I was on international flights without a power port. If you really need a lot of run-time, you can always buy extra batteries. I prefer to sit near a plug.</p>

<p>The battery by itself doesn’t determine how long it’ll last. It also depends on how much power the laptop draws.</p>

<p>I ended up getting a Thinkpad T500 with a 9-cell battery because it had a 15.4" screen that makes it comfortable for use, but also the DDR3 RAM that made its power draw very low compared to similar laptops. It lies flat and the battery lasts more than 6hr on 75% brightness.</p>

<p>Meanwhile, my old laptop was very cheap (costed only a third as much as my current one when it was new), but it was a Toshiba. It had a 3-cell battery and used some high power draw components. The battery life only lasts 90min on that one.</p>

15

<p>I have an HP laptop with a 6-cell battery, and the battery life is okay, but not great. It really depends on how bright you want the screen–at the brightest setting, the battery will only last about an hour and a half. At the lowest, i’ll get three hours, but it’s also nearly impossible to see the screen at its lowest setting (meaning I usually get around 2 hours of battery life, since I tend to stick somewhere in between the two). Also, I’m sure more energy-efficient laptops last longer on one charge than ones that aren’t energy-efficient.</p>

<p>I have an E6400 with a two 9 cell primary battery. It gets 7 hours per battery so 14 hours of runtime is more than sufficient for most tasks.</p>
