Hi,

Welcome to the Community. Check the below link on Dell Battery Laptop Faq's.

It depends on how old is the battery. Batteries come with a 1 year warranty, so if its over a year old and its giving about 2 hrs of backup, then its normal.

Thank you.

Thanks for the info.

Mine lasts 1.5hs, using wifi.

I just wondered if it was worth getting a new one... but perhaps not. The laptop is not that used.

Is a 9 Cell much heavier?

Thanks

Hi,

If you get 1.5hrs on it means it still has life. Check your Battery Meter how your battery is performing. Yes the 9 cell batteries are heavier than the 6 cell.

Thank you.

Thanks for info.

How long would a brand new battery lsat - using wifi - I wonder if its worth getting a new one. MUch longer than 1.5 hs?

How does one do this?

Hi,

A new 6 cell should give you 2-3 hrs of backup. This depends on alot of factors, from what type of applications you are using, the brightness on the computer, memory, processors etc. Check for a battery icon on the left side bottom corner, and click on it to bring up the battery meter.

Thank you.
