SFD07 Posted February 7, 2007 Share Posted February 7, 2007 I run my laptop off AC power while at work (~6-8 hrs) and battery power at home (~1-2 hrs). When I bought it last year (September or so), one of the employees recommended removing the battery while running off AC power to 'preserve it', saying that leaving it in while it's getting AC power can shorten its life due to heat.. I didn't think much of it and just took his word for it, removing the battery every day at work (once its charged) and plugging it back in when I get home. I havent seen any other comments about this and it's starting to become a bit of a hassle to do every day. Is this true or am I just wasting my time? I wouldn't mind continuing this process if it will actually preserve the overall life of the battery but I'm starting to feel like I'm just doing it for fun. Anybody know?

TurboTuna Posted February 7, 2007 Share Posted February 7, 2007 If you have a decent laptop it will cutoff power to charge the battery once it gets to a particular point as to not "damage" it. If you have a cheap generic battery then removing it would be an option but i wouldn't bother. imho, i wouldn't be able to justify the time taken to remove the battery and put it back time after time after time and would just leave it in there.

bigcalmr Posted February 7, 2007 Share Posted February 7, 2007 I wouldn't bother with removing the battery when using the AC cord. I'm sure that is getting old! I work with Dell, HP, and lots of IBM/Lenovo notebooks... and never had an issue w/ early battery deterioration. Now, I have seen many batteries "die" after several years (4+) of use, but feel that it is a typical occurrence of the batteries made today.

J400uk Posted February 8, 2007 Share Posted February 8, 2007 I bought a dell inpsiron 1300 last april and have always left the battery in. Now it only holds a 45% percent charge :( Link to comment Share on other sites More sharing options...
arturogoga Posted March 25, 2007 Share Posted March 25, 2007 I'm also interested in this subject, since I recently bought my first laptop (an Acer Aspire, mostly for college stuff), and the store clerk told me the same thing - to remove the battery when unused. However, since she also told me I had to let the laptop do a full charge/discharge cycle (which was wrong, since with Lithium-Ion, that method of charging isn't necessary), I'm having my doubt about the whole -remove the battery to preserve it, thingie. Any advice on the subjetc? Link to comment Share on other sites More sharing options...

Any advice on the subjetc? In terms of charging/discharging, its still recommended to do such procedure even on Lithium Ion batteries. Why? Lithium ion batteries begin to lose their charge capacity the moment it leaves the warehouse of production. Doing the charge/discharge cycle 2-3 times gives the cells inside the battery some workout and gets them ready. Here's a few very helpful links from HP that contains very accurate information. Calibrating your battery Understanding Lithium-Ion batteries How can I maximize the discharge time of the battery?The discharge time will vary by user. It depends on the features you are using while on battery power. For example, if you are playing a DVD and are connected on a wireless network, your battery life will be shorter than normal. If you are just reading or editing a file or answering e-mail on a wired network connection, you will experience maximum battery life. Please note that maximum discharge time will shorten over time, as the storage capacity naturally decays. Tips for maximizing discharge time: Lower the brightness on the display. Check the Power saver setting in Power Options. Remove the battery from the notebook PC when it is not being used or charged for a long period Purchase another battery to extend the overall operating time on battery. Store the battery in a cool dry location. Will the battery performance degrade over time? The storage capacity of the battery will degrade over time based upon usage of your notebook PC. This degradation is normal for all rechargeable batteries and is not specific to notebook PCs or HP products. If you run your notebook PC on battery power often, requiring one or more recharges per day, the battery will degrade faster and require replacement sooner than a battery that is used occasionally. Temperature and humidity also impact battery storage capacity. Store the battery and notebook in a cool, dry place. Under normal operating conditions, a battery should perform well for over a year, but it will retain less charge each time it is recharged. HP Battery Check will display a "Replace" status if the cells are not functioning normally. Link to comment Share on other sites More sharing options...
trek Posted March 25, 2007 Share Posted March 25, 2007 I bought a dell inpsiron 1300 last april and have always left the battery in. Now it only holds a 45% percent charge :( less than 1 year and you lost >50% of the capacity? time to call dell... Link to comment Share on other sites More sharing options...
gnuman Posted March 25, 2007 Share Posted March 25, 2007 hence why i recommend to take out the battery as well. I haven't used the batteries in months. Also to prevent the dreaded DC in jack issue (where you plug in your laptop from the DC jack) I would recommend disconnecting it from the adapter box and not pull it out from the laptop itself. Remember when plugging and unplugging the solder that holds the jack will get loose from all that pressure. It will save you a motherboard but really you can solder it, Link to comment Share on other sites More sharing options...
.Markus Posted March 25, 2007 Share Posted March 25, 2007 I've never encountered any shortening of battery life with my three Sony Vaio's. It has been pretty much static throughout, without bothering removing the battery... Link to comment Share on other sites More sharing options...
