Everyone who travels with a laptop knows that gut-wrenching feeling when you�re far away from an outlet and your battery is at 4%, and to top it off you�re halfway through writing a report for your boss. This is not a feeling anyone wants ever, and so American Power Conversion came out with 3 Universal Notebook Batteries at CES. The 3 models are the Universal Notebook Battery 50, 70, and 90. The smallest one (the 50) retails at $100 and is supposed to provide up to 4 hours of battery life, depending on what you�re charging. What�s great about this model is that it is really small so you can take it almost anywhere without a problem. The middle one (the 70) is set to retail at $150 and is said to give an estimated 6 hours of battery life. This one is a little bigger, and it can go underneath your laptop. Now for the big daddy: the 90 is said to give a whopping 8 hours of extra battery life and is set to retail at $200. This one is just sweet because it fits under your laptop and has an LCD to tell you how much battery is left. If you�re prone to forgetting to charge your notebook, or you just are away from a charger for long periods of time, spending $200 on the big battery might be a great purchase for you. — Nick Rice
