Extending the life of my laptop's battery

Dear CNET members,

Happy Friday! Just a quick announcement for all you Dell fans, owners, or potential Dell product owners. CNET has recently partnered with Dell to bring you the Dell forum on CNET. This forum was built just for you so that you can talk shop about anything relating to Dell products. And the best part about this forum is that there will be Dell representatives present to take part in the conversation. So if you have Dell product questions, troubleshooting needs, or just simply are in need of some buying advice from your fellow members or Dell staff, swing on by this new forum and get your post on! Now let's tackle Raji's question on how he can extend the life of his new laptop battery.

This past week we received a bunch of answers from our members regarding Raji's questions on how he should properly maintain his new, expensive lithium ion laptop battery that he just replaced. However, although many answers were submitted, many members gave general answers on how to maintain batteries that weren't necessary specific to what Raji owns, which is a lithium ion (Li-ion) battery. And Li-ion battery maintenance differs quite a bit from nickel cadmium (Ni-Cad) or nickel metal hydride (NiMh) batteries. For example, Li-ion battery should not be frequently discharged and recharged (or cycled through), whereas with Ni-Cad or NiMh batteries, deep cycling is a known practice to help preserve the battery's life. In fact, Li-ion batteries shouldn't be completely drained at all, as this hurts the battery.

These are just a couple of the many things that make Li-ion batteries different from their older counterparts and it just goes to show that not all batteries are created equal. Depending on the type of battery you have, there will be different methods of maintenance used to prolong the life of that particular battery. So please check out the few selected answers in the Q&A section that go over in detail the dos and don'ts on Li-ion batteries and hopefully Raji, you'll have enough information to go on to prolong your new laptop battery. If not, there is always the link to Wikipedia that member Aparicio Mart?nez provided that will surely help. Thanks everyone for you participation. Have a great weekend!

Cheers!

Last week's question
Extending the life of my laptop's battery
QuestionHello, I have a HP laptop that about 1.5-years-old and its battery is in such a pathetic state. When I pull the plug on it the laptop, it completely dies off (shuts down). It's as if my laptop is on a respirator (the battery) and it can't breathe on its own. Since it was getting highly frustrating that my original battery would not hold any charge whatsoever, I resolved to get a 12-cell lithium ion battery. Now, I am more concerned about how I can use my battery more efficiently. What should I do to preserve the condition of my new battery so it can work longer? It is expensive to replace a battery every year. Please let me know what all I can do to extend the life of my battery. Should I be plugged in all time while I'm using my laptop or should I charge and discharge it? I will greatly appreciate your recommendations. Thank you!

Check out next week's question:
Should I go with digital compact or a digital SLR camera?
Next week's questionDear CNET friends, you've shared so much valuable info with us over time that I feel you are really good friends. Thank you! My question is in regards to choosing a digital compact or a digital SLR camera. Finance is an issue though I am willing to save up till I can get what I want. I love taking macro shots but also like using zoom for better bird shots. My present camera is a compact Canon Powershot A620, 7.1 megapixels and 4x zoom. It's been a great camera for me but now that I've learnt more about photography it's time to move on.

I had almost decided to get the best Canon compact with 18x zoom, but a camera salesman told me if I want good (sharp) macro shots I'd be better with a lower price range SLR body and pay extra for a reasonably good macro lens. His opinion is that Canon had added more zoom etc. to their compacts but that the lens was still the same quality. Could someone please advise me for what I need? Many thanks in advance.
