<p>is it a bad thing to use the battery power? lots of people use the adapter, but i don't want to carry it all around. i just charge the battery over the night when iti runs low.</p>
<p>i've heard that for cell phones, it's not good to charge the battery only when it's hald full. it will gradually diminish the battery capacity.</p>
<p>in the case of a cell phone, it’s just the first few charges. afterwards you can recharge whenever you want. all rechargeable batteries will lose capacity over time, regardless of whether you discharge it fully every use.</p>
<p>there’s nothing wrong with using the laptop battery, just keep in mind that it can only recharge so many times before you need a new one. not many people carry around the adapter…they just leave the computer plugged in when it’s at their desk. there’s no point to using the battery all the time, other than shortening its life.</p>
<p>You can also remove the battery when you are working at your desk and use only the adapter. This will also increase your battery life. Just don’t forget and unplug it without shutting down :)</p>
<p>aswat made a good point… most people think that using the computer on battery power will ‘wear it out’ but in reality it’s far worse for the battery to leave it plugged in on full power all the time. That will kill the battery really quick. As a rule of thumb, you should run your battery down to near empty at least once per week. If you alway just use your laptop at your desk then just unplug it and run it on battery power about once a week.</p>

<p>false. the battery should only be run all the way down (as in until the computer shuts itself down, not literally 0%) every few months to calibrate the computer’s power management software. leaving the battery while the computer is plugged in will not “kill the battery quick.” it will shorten its life faster than it will naturally, but that doesn’t make it anything near quickly. leaving it in for a few days or a week or two won’t do much. leaving it in for a month certainly won’t kill the battery either.</p>
<p>if you run the computer without the battery, discharge the battery to 40% first. it will preserve the battery’s capacity best.</p>
<p>How do you not notice? the weight of my macbook pro goes down by like 2lbs when I take out the battery. Not to mention the giant indent in the middle of the bottom of the laptop.</p>
<p>And with the magsafe thingies and if you use it a lot on your lap, you DO want to keep the batter in, just in case the magsafe falls out, as it often does.</p>
<p>If you have a high performance laptop (read: runs hot), remove the battery while you’re using the power adapter. The heat from the system drains the maximum battery capacity quicker.</p>
<p>You should never deplete a lithium ion battery entirely. This damages the cells inside- and, if your battery is left depleted for too long, it could dip below the minimum voltage, rendering it unusable.</p>
<p>You should only buy lithium ion batteries as soon as you need them, with the most recent manufacture date possible. If you will not use them for extended periods of time, keep them in a cold environment- above -40C but below 0C. This will minimize loss. Also, the ideal charge for long term storage is about 40%.</p>
<p>You should, however, do a decent discharge once every 5-10 cycles- around 30%. This will keep the battery life accurate on the PC.</p>
