Q: i just bought a dell laptop battery here: http://www.power-battery.com.au my question is:How long does a Dell laptop battery last? When should I consider replacing mine? thank you.
A: Depends on how much you use your laptop. I had dell Battery and I was a heavy user like i used for many hours each day. It lasted me about 1 and half year. Replace it when you start to get fewer juice from it with each passing day. The more quicker the battery is discharging when youre using it, the faster it coming close to dying.
