I thought I would write a little guide on Acer 2480 Travelmate laptop computer batteries. This computer only comes with a 2000 mah battery which at full charge lasts only about 30 to 45 minutes. (Hardly worthy of calling it a laptop as it is not useable for any length of time without having an outboard plug-in-the-wall power supply). The good part is that there IS larger capacity batteries that are available. There  is a 4400 mah and a 6000 mah battery available. Now to the point of why I am writing this. Please BEWARE there are sellers here on Ebay that are selling the WRONG battery for this laptop. Please look at the picture below. The one on top of the box is the one that was sent to me that I purchased on Ebay it said in the auction that this battery was compatible with my Acer 2480 Laptop Computer. The one that is in front of the box is the actual battery that is out of my Laptop. You can clearly see it is totally different. Its not even close and the shame of the whole situtation is that 90% of the Ebay sellers that ARE in fact selling the wrong battery for this laptop. I am not saying these sellers are bad. I am saying that they need to check more carefully into the correct information in what is compatible and what is not instead of copying someone elses auction and getting the wrong information. I have lost weeks of portable usability of my laptop because I was sent the wrong battery. Fortunately the people that sold me the battery here on Ebay are more then happy to rectify the problem. I would be willing to bet that there are alot of batterys that are the wrong ones too. Please remove your battery from your laptop and compare it to the pictures the Ebayer has listed and don't be afraid to ask if it will fit your computer. Also state the make and model number of your computer when asking. Another nice thing to do is this, if you notice the Ebayer has the wrong battery listed then tell them so they know its wrong, this also lets them correct the mistake so other Ebayers (Like me) don't get the wrong battery sent to us.  I have just found out there are other issues with this battery and MANY others that are sold here on EBAY save yourself alot of headaches and ... ****** PLEASE SEE MY OTHER GUIDE WARNING THAT THESE IS COMPATIBILITY ISSUES WITH ALOT OF THESE BATTERIES IF YOUR RUNNING WINDOWS XP AND OR WINDOWS VISTA ******
