Not compatible with Inspiron 1505, October 5, 2009

Hi All,I have been a great fan of all products and customer reviews provided at amazon. This is the first time that a product that had 17 4 reviews failed miserably. The battery seems to be not recognized by Dell. Once I put the battery in my Inspiron E1505, on booting the laptop, i get the warning message stating"Warning:The model number of the primary battery can not be recognized by DellThe battery would not be charged."I spent almost 2 hours trying to resolve this issue, upgraded my bios from A03 to A17 but still nothing changes. Either all the 17 4 reviewers were affiliates of the seller and are bogus or my case is a one of scenario. Whatever be it, I am highly dissatisfied by the product and would appreciate if anyone knows of a valid solution for the 50$ spent on this item.

Just a little tidbit for everyone using laptop battaries(specifically LI-Ion)Most battaries that favor a constant charge and recharge capacity work in two different forms. Your standard Ni-Cd or nickel cadmium battery is a slow drain slow charge type battery, a complete drain and recharge is a standard that most of us know. Not the case with Li-Ion, the lithium battery, and newer Metal Hydroxide batteries work better and last longer using the 100-40-100-20-100-40-100-40-100-20% recharge plans. On your initial charge of 100% charging you let the battery drain to 40% and then recharge to 100% and then the second depletion to 20% and back to a full recharge cycle. This helps maintain the battery condition and in some aspects the "Brain" of the battery so to speak is set in motion and maintains battery health througout time.I myself thought the cycle was complete depleation of the battery on each recharge which actually shortens the life of the battery.(learn something...

In spite of Amazon's product title, this battery is not compatible with my Inspiron 1505. The 1505 does not recognize this battery, and it does not charge. Save yourself the aggravation, and avoid this product.
