Hey, I'm just wondering as to what everyones avg battery life is for their notebooks, and what their specs are. Personally, my battery life sucks...I unplug it and walk upstairs, and its down about 3-4%...its almost pointless as a notebook...so is there any way to improve battery life? Any tips/suggestions would be nice.

Buy a new Centrino notebook!

Seriously! The power management features double the best battery lifespan available in any other form of notebook.

Well, I've already bought one...as I said. So I can't quite buy a centrino, I'm just wondering what everyone else's battery life is like, so I can compare to mine.

I hear ya...my battery life on my laptop is now down to the order of 15-20 minutes now.

what is the avg life on batteries and how to best preserve/maintain/take care of Li-ion batteries?

these days, I often leave my laptop plugged in much like a desktop for extended periods of time (days or even weeks) and wondering if it's worth the trouble to remove the battery.

The only plus I can think of leaving it in is you've got pseudo-built in UPS :)

Any comments appreciated!

Don't leave ur laptop plugged in persistantly, it wont do the battery any favours because while your leaving it on the mains its constantly putting charge into the battery and therefore shortening the battery life. these batteries do have a memory in them. the more you charge them the less output you'll acquire from them. try taking off the charger and only charging when you need to i.e when the laptop only has a few minutes left.;)

hmm..i would figure that everytime you want to dock your laptop while you're at your desk, you want to charge the battery, use your laptop for some period of time before you undock. I can only imagine the standard design spec is to leave the battery so as to avoid the hassle of (1) unplugging your laptop all the time or (2) removing the battery when its full.

in other words, a circuit in the laptop would stop charging the battery when it was full...something wrong with my logic?

at this point, the battery is so toast, i just leave it plugged in all the time! a bit of a sacrifice for convenience :rolleyes:

ok, let me point out that I dont have a docking station for my laptop. apparently they dont make them for my particular model anymore.

It sounds like your battery has been over charged or has just simply got old. Im remaining neutral here so I'm not going with any logic. thats not saying whether you are right or wrong tho.;)

Thanks for the input guys!

Yes - my battery is definitely old and admittedly, I bought a refurbished battery 2 yrs ago - my mistake - you get what you paid for! (ie. $50 for a $150-200 battery!)

When I'm ready to upgrade my laptop and start over - I'll definitely bring this issue again!

My internal laptop battery life also sucks. My solution was to pick up a batterygeek ultra high capacity external laptop battery which is now giving me over 6+ hours of run time per charge. Also, they have a full 1 year extended replacement warranty. They also offer some nifty free gifts... Thier website is at www.batterygeek.net

Best of luck,

I just received a lease return PC off of ebay. A Panasonic "TuffBook". Processor speed is 1.8, ram 1/2 gig, 100gig HD, dvd and wireless. Testing it out it started by saying it had 100% and 2 hours life. An hour has passed and now it says just under 2 (1.45) @60%.

Does that sound like reasonable life span?

Cheers!

yeah 1 to 3 hours is average

I got a Lenovo c200. 1.78ghz Core Duo and 2gb of ram, dvd, wifi, and 120gb hdd. I get 1.5 to 2 hours out of it.

As a general rule with pc laptops, less than an hour is bad (but acceptable for a used laptop as after a few years the battery will be worn out so it only works for like 20-45 mins) and more than 3 hours is good.

@ jbennet,

Thanks for the reply. That is good to know. This is my first laptop and as a refurbished (eBay) machine, I wanted to ensure it was as it should be. It kind of ended up being a bit pricey, around $400 CAD after shipping and duty. But, so far it does seem to be a good machine. Just need to get the speakers working....

Cheers!

One would think that was a sensible idea... try telling asus that. they will probably jump on it and you will get... well, I couldn't possible say - but don't expect anything and you won't be dissapointed.

I have an ACER extensa 2000. batt life was around 2 h (5 yo notebook) but now I cannot get it under 45 deg celcius, the fan goes constantly and I am lucky to get 20 mins.

Well, one thing I can definitely tell you is that the laptop makes all the difference in the world. My Acer 3502WLCi has a battery life of approximately 30 minutes, while my Compaq Presario F769WM will run about 3-4 hours on it's battery.

My notebook specs dell n5010.

Notebook computer to plug in the power match does not boot, you can charge your laptop. Most books are charged in this way. The proposal does not plug in the AC charging boot, so easy to notebook battery saturation charge. Other batteries and some tips:

Finally, in the long-term use of AC powered battery, so the AC repeat to charge the battery, the battery's charge cycles with certain restrictions 9000.

2, the battery is not used, over time took them out once, to charge and discharge, to prevent premature battery aging.

3, not every time when a battery with the cleaners, but over time also need the battery to the two deep charge deep discharge, battery use cleaners for a long time sufficient, thus extending battery life.
