How to increase the battery life of a Compaq Laptop.?
I have a Compaq Presario CQ 60 209TU a 16 inch laptop and it gives around 3 hrs of battery life. I saw Macs(8 hrs) and other laptops such as dell(4-5 hrs) having better baterry life. Can I increase my battery efficiency or change my battery to a more powerful one(9 cell battery).How much would it cost??If possible please provide me the links. Thanks in advance

There's a huge difference between the cheapest and smallest laptop batteries and the more powerful ones. They usually run $60 to $150 and give about 500 charge/discharge cycles before losing capacity. You get what you pay for, and original manufactured batteries are often best. Your best bet is to use them only when you can't plug in so that they last. Otherwise, the lithium just breaks down a bit each time you go through a complete cycle.

Well, simple ways for you to increase battery life: -Turn your brightness down to low. -Use power saving options in the power window. -Turn off unnecessary peripherals (such as wireless) if you aren't using them. You would increase your battery's capacity by getting a 9-cell battery, and they cost about $80 (maybe a little more, maybe a little less). However, you won't be getting 8 hours on a 9-cell battery. Maybe about 4-5 hours maximum.

By visiting the HP website, I have found a guide on how to Improve the performance on your Laptop's battery http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01297640&tmp_track_link=ot_faqs/top_issues/en_uk/c01297640/loc:1&lc=en&dlc=en&cc=uk&product=3876940&lang=en

My Macbook pro doesn't get 8 hours. Those specs you read are just marketing hype. Most laptops if you are doing anything serious on them will get about 3 hours or less nominally. If it is new, yeah you'll get a good charge, maybe for the first 2-3 months. After that, don't expect better performance. They get those numbers by turning everything you need off. Turn off Wireless, low brightness on panel, don't play any music, don't run too many apps - and there's your max battery life. It is worse than the MPG ratings on your new car. Batteries degrade. Even the newer Li-ION ones. They degrade faster if you plug / unplug / plug and don't follow the directions given by the manufacturer. As they degrade, it holds less charge for you to use. At some point it won't hold a charge at all. If you suspect you're not getting good performance from a battery, your best bet is to replace the battery with the "original" manufacturer one. And don't buy it from some weird place you've never heard of, and don't buy a after-market, that is touted as good as the original equipment. Always recycle your old battery.

Make sure you lower the brightness, set it to sleep if youre going away for a short amount of time, turning it off when you aren't using it, removing the battery if you have the ability to use the charger instead, and make sure you go to Power Options and set it so it saves power. Good luck!
