How long does your laptop last on batteries. I've a P4 Vaio desktop replacement. Its a few years old, has a P4 2.8ghz and on a single battery lasts about 1.15. You can stick two batteries in it and it doubles the time to around 2.30hrs. Its a lovely machine to use though with a 16.1" screen and nice keyboard.

Recently I've got a 14.1 Dell 640m Dual Core 1.83ghz. I don't think I'll be keeping it. But it has a 9 cell battery and lasts for about 7-8 hours which I thought was quite impressive. I was wondering what other laptops people have which have decent battery life. Especially Vaio's as I might get another.
 
(Old) Compaq Presario 705ea - AMD4 1Ghz, 15.1" TFT - 1hr 20mins... not bad for a 6 year old laptop!.. :)
 
Got a Dell Inspiron 630m (Pentium M 1.73GHz) with battery life of around 4.5 - 5 hours. Thats with the 6 cell battery.

Must get round to tweaking with the CPU voltage so I can squeeze even more out of it. Pretty tempted to get the 9 cell as I could use it throughout the day and not worry about it running out.
 
Compaq Presario 2100 which is an XP-M 2400 I think and that should last approx 1 hour according to Windows power management but then it is several years old now and I haven't tried setting up any power saving options.

No, no, don't have it plugged 24/7! I did that to mine and now the battery doesn't work, so 0 hrs. It is recommended to alwyas charge a battery fully and then use it till it diescharges completely to make it last. I apply that to mobile phone batteries as well.
 
Whose heard of the prototype methonol membrane battery they were developing at one stage. Something like 4weeks 24/7 battery life on a laptop, more than a year on a cellphone, and its supposed to be environmentally friendly :confused:

Not with Lithium Ion batteries! Thats one way of reducing the life of the battery. Warm temperatures is another along with the number of recharge cycles as you'd expect. That method was recommended for the older batteries and doesn't apply to the Li-Ion batteries.

You should only let is discharge now and again, never all the time. Best thing to do is charge it, let it run down to around 25% and then charge it back up again. If you're not planning on using the battery for a while, its best to store it with a 40% charge.
