jkandra Posted December 15, 2005 CID Share Posted December 15, 2005 How long should the life of a battery in a Laptop last? Mine lasted for 2hrs. Is that good or bad? This is a brand new Laptop 3 weeks old. Most of the time it was sitting on the table with testmy.net page open while I was trying to fix my granddaughter's intercom.

richcornucopia Posted December 16, 2005 CID Share Posted December 16, 2005 2 hour battery life doesn't seem to good for that model when it is supposed to get 4 hours and 24 minutes. I'd call hp or if you bought it at a local retailer, call them and ask about getting a new battery maybe they would replace it for free.

jkandra Posted December 16, 2005 Author CID Share Posted December 16, 2005 This is what I found on Batterys from HP. I guess the battery is only to last 2-4hrs.

richcornucopia Posted December 16, 2005 CID Share Posted December 16, 2005 I see, I guess the site I saw was showing the best possible battery life. So 2 hours is right in hps specs of 2-4. Quote Link to comment Share on other sites More sharing options...
jkandra Posted December 16, 2005 Author CID Share Posted December 16, 2005 Thats terrible Isn't it. They should last longer. Quote Link to comment Share on other sites More sharing options...
richcornucopia Posted December 16, 2005 CID Share Posted December 16, 2005 What were you doing when it lasted 2 hours? If it was watching a dvd or something else very battery intense then 2 hours isn't too bad. But if it was just simple word processing or internet browsing then you might want to see If you can get a new battery. Quote Link to comment Share on other sites More sharing options...
jkandra Posted December 16, 2005 Author CID Share Posted December 16, 2005 I was working on a project and the Laptop was left unattended with the testmy page up on the screen. I will keep an eye on it for a bit to see how long it last, then I will call HP. Quote Link to comment Share on other sites More sharing options...
wingzero2309 Posted December 16, 2005 CID Share Posted December 16, 2005 It depends on your laptop and what you're doing. If you're gaming while on battery, then it'll of course run out fast. I get 3-3.5 hours on mine (with brightness at level 2 out of 7 and wifi on). mine is a 17in w/a GeForce 6800go, which are both pretty taxing on the battery. Oh, and its a 9 cell battery. The Pentium M is probably what is allowing me to get decent battery life though. But yeah, most laptops generally have anywhere from 2 to 7 or 8 hours of battery life (this is under the assumption that it's not being used for gaming or CAD rendering or something of the sort) Some manufacturers have like 12 cell and 16 cell batteries too, so if you want more batt life, you might wanna find out if your manufacturer has higher capacity batteries Quote Link to comment Share on other sites More sharing options...
Dirk Posted December 16, 2005 CID Share Posted December 16, 2005 I'm using a Compac EVO 610, and have a battery life of about 4 hours as a maximum, and that is with word, excel and filemaker open. Sometimes with older batteries, they will loose some capacity, and if you think the battery is really dead, get a ziplock bag and put the battery unit it there, and put the whole in the freezer for a few hours. You would be surprised how much the things improve with a temperature reset. (My battery went from 45 minute capacity to 4 hours again) Quote Link to comment Share on other sites More sharing options...
Dark_Matter Posted December 16, 2005 CID Share Posted December 16, 2005 When they say 2-4 hours what they really mean, but don't say usually is this 4 hours doing basic computing such as email, and internet. Even then your only likely to get 2, and a half 3 hours tops, 2 hours if you are doing intense things like playing cd's video editing ect even then don't expect much. battery life has always been a real issue when it comes to laptops.

resopalrabotnick Posted December 16, 2005 CID Share Posted December 16, 2005 i haven't seen a single laptop that has that one feature i would be willing to pay extra for. an internal battery that has just enough juice to run the thing for a few minutes, 3 or 5 or so, or even less, so you can swap the normal battery for the spare without powering down.

Right now I have an old one that only holds about 25 minutes and was about to buy a new one but then I saw this. What type of battery were you freezing, and is there a certain type that you should, or shouldnt put in the freezer? Quote Link to comment Share on other sites More sharing options...
Dirk Posted December 18, 2005 CID Share Posted December 18, 2005 All i know that it is a lithium ion battery that came with this laptop. it is not the original (slight color difference with the rest of the laptop) but it does the job quite fine. 14.8V 4400mAh 6 cell battery that goes in my laptop Quote Link to comment Share on other sites More sharing options...
richcornucopia Posted December 18, 2005 CID Share Posted December 18, 2005 Well I just put my laptop battery in the freezer, we'll see what happens in an hour or so. Quote Link to comment Share on other sites More sharing options...
