Laptop battery Reivew:

“For those that are confused about the physical size of the replacement battery, this is an extended size dell latitude e6220 battery. There is the standard size that is flush with your laptop when inserted and there are the extended sizes that protrude out approximately one inch from the back of your laptop. You will find this same protrusion on any extended size battery you purchase directly from Dell; it will stick out the back a little and that is normal. The standard size is a six cell battery and will give you a shorter run time on a charge. This is a nine cell battery; this is how they get more run time out of the battery… it’s bigger ;

You can save yourself some headaches though on having to replace your battery more often than necessary:

– If you generally have your laptop plugged in and the dell e6430 battery is sitting there fully charged all the time, unplug it and let the battery run down a bit (about 40%) and then remove it. Your laptop will function just fine without the laptop battery. When you need to use the battery, put it back in, let it charge up a bit, and use it.

Well, a few months down the road has passed by. First, a little background info so you can relate my usage to what I am saying. I am a full time tech college student, I drive a small fifteen minutes both ways to campus, and I attend class four days out of the week. I have the computer on pretty much the whole time as that is where I store my notes, take my notes, and do some of my homework. I use the the battery for latitude e6220 fairly frequently. With all that use my battery still reads 6.5 hours. Not sure if it is reading right or not, but it does hold a charge through all my classes down to about the 15-20% mark at worst (depending on usage). I do keep the battery on power saver settings while in school; display dimness turned all the way down, display turns off in 3 minutes, goes to sleep in fifteen minutes, and WiFi turned off unless I need to look something up. I do occasionally turn the display brightness up, but turn it back down after. One needs to realize that the more you are demanding out of your laptop it will shorten how long your battery will keep the laptop running; I am pretty much using it for Office 2007. I remove the battery on the weekends as I can run it off the power cord at home.”
