For a few euros more, this battery lasts much longer than the basic battery (4400 mA) Used on a HP Pavilion G61 According to my initial tests, it takes to charge about 1% per minute (100 minutes for a full charge) which is quite long but not déconnant Autonomy in semi-intensive operation (intensive surfing the Internet) is up to 6 hours which is significantly better than the basic batteries but it is of course to be expected that these performance degrades over time. This applies even when the cost given the small difference in price (10) Disadvantages: -Battery Spring 2cm in thickness and enhances the PC at the back but honestly this is rather an advantage, this will comfortably raise the keyboard and prevents heat underneath. -The Weight is significantly higher and significantly increases the PC besides the clutter that may interfere in the pocket In summary the benefits far outweigh the few drawbacks to know before you buy.
