What a disappointment. My dell battery now needs to be completely replaced after a mere 13 months of service. Even worse, the battery stopped providing reliable power without being plugged in only a couple months in to owning my computer. It'll now cost me about $150 to replace this piece of crap with another one just like it. If actually want a halfway DECENT batter, it's going to run me $300.
To anyone thinking about purchasing a middle-of-the-road model Dell laptop, I'd advise you to do your research on what batter you're getting and insist it come with a proven performer that won't crap out after a year like mine did.
