EatOut Member 38 Posts 5/08	Posted - Dec 13 2008 : 12:27PM What's the name of the longest lasting (from one charge) laptop battery? When I say 'name', I mean maybe you know a brand name that stands out from all the rest. Sort of like the Ferrari of laptop batteries, if such a thing exists. And how many hours would you expect to get out of it from one charge? My laptop is an old 2003 Dell Inspiron 5100: http://www.pcmag.com/article2/0,1759,997075,00.asp [Link]

It's not like laptop batteries are "standard" and can be swapped between different makes and models like AA/AAA/C/D sized Duracells and Energizers. I can see comparing the runtime of different laptops but not comparing the batteries in them. [Link]

Click to expand Until recently you could pop off the plastic enclosure of a notebook Li-Ion battery and find standard 18650 cells that could easily be replaced. It's harder now for two reasons. First, modern batteries are Li-polymer and pretty much whatever whatever shape the designer wants. While you might be able to open the battery pack up and find Li-Poly cells on the market to put in the pack that may be wishful thinking. Secondly, modern notebook batteries are getting smarter and the microprocessor in the battery pack less forgiving about unexpected events on the battery cell terminals. Even if you can replace the battery cells the pack controller may refuse to cooperate. Finally remember that Lithium batteries are, with few exceptions, quite hazardous. They don't explode often any more but they can start a fire bad enough to burn you house down, and the chemicals released can be very toxic. Be careful about buying replacement batteries purely price. [Link]

Click to expand The few notebook battery packs that I have opened have all had a string of cells soldered together with conductive strips. I figured this isn't the kind of thing the typical user could handle. [Link]
