Hi All, I hope I'm not breaking any rules by asking this question... The 6 cell battery in my HP ProBook 5310m is pretty much worn out. It lasts approximately 15 minutes on a full-charge. I want to buy a replacement battery , however considering the age of the laptop (almost 2 years), I'm not wanting to spend a lot of money on it. I really just want to keep the laptop useable for maybe another 6 months or so when I'm planning to replace it. I figured it might be worth going for a 9 cell, as even when the laptop was brand new, the 6 cell never lasted more than 2 hours on a charge. From research I've done this seems to be less than normal, however I suspect this might be because I opted for a faster 7200rpm drive (wasn't a standard option, had to specifically request it by phone). Can anyone recommend a good place to get good quality (non-genuine) replacement batteries for Dell laptops? It doesn't need to be as good as a genuine Dell, but I obviously don't want the thing to leak or explode either. Thanks, Eugene
