View Full Version : [other] End of life for laptop battery

June 2nd, 2012, 08:37 AM
I bought a second hand Dell Inspiron 6400 laptop back in 2010 and for the last two years has performed very well. I have just discovered over the past couple of days that I have a problem with the battery. I first discovered the problem when I was running Kubuntu 12.04 from a live disk, KDE told me that the battery had a fault and had a capacity of 48%.

When I connect the laptop to the AC supply it charges up the battery as normal but then once removed from the AC supply it loses power in a short space of time. I was searching the internet last night to see what the life span of a typical laptop battery was and according to Dell the battery lasts on average between 18 and 24 months. Considering that this laptop was built in and around 2007 I think the battery has lasted quite a long time.

I was also looking at the Dell website for a replacement battery and could not believe the price they were offering for a new battery. 103!, I almost fell off the sofa! I then searched Amazon.co.uk and found several replacement batteries much cheaper but are not genuine Dell batteries. The feedback I had read regarding these compatible batteries are quite good but does anyone know if they will last as long as 2 years or so?

i dont know about your battery, but mine needs time to time to refresh it: the bios have a setting to force emptying it before getting a new full charge.
