Hi, is there anyone out there who can tell me why my Samsung Netbook NC 10 battery has a lower capacity each time it is used? I have tried using the mains lead where possible but as soon as I try using battery power, the time available is now down to around 30 mins!!! at this rate I will not have the option of using it as a portable device. I am aware that the battery life quoted is that under minimal load, but surely I should get more than a measly 30 mins out of it? The netbook is now just over a year old so no warranty.
Laptop, notebook & netbook batteries have a limited lifetime, but this can be extended by treating them carefully. If you discharge it fully and then recharge it fully three or four times you might be able to rejuvenate the battery. If this doesn't work you will probably need to replace it.
I've just got a new battery from SuperEtrader on Amazon for my Advent 4211 netbook. It's twice the original's capacity, was at a good price and arrived the next day even though I didn't pay for express postage and got free delivery.
Try doing a Google search for replacement laptop/netbook batteries.
How old the Netbook, I have this same Netbook and had it about 15 months mine seems just as good as when I bought it. Have it set to run on battery for about 6 to 7 hour settings though it will run longer if I really push it on power saver features. you may have a poor battery
