Laptop Battery

I recently bought my first laptop. My desktop is not set-up at the moment. Does it make any difference in battery life if I keep the laptop connected to the charger? How often does the battery need to be discharged?

thanks in advance

Re: Laptop Battery

Most, if not all, new laptops (I assume it is a new model) use a Lithium Ion (Li-Ion) battery which does not have to be periodically discharged and can be plugged into an AC outlet indefinitely without causing any harm. These batteries have a longer life and are more stable than Ni-Cad and NiHM batteries used in the past. They can be overcharged, but the batteries contain built-in circuitry which monitors the battery's condition and prevents this. Personally, I leave my laptop plugged in until I travel, so it may go months at a time without being removed from an AC current.

Thanks for answering my question. My laptop is about 3 months old. Now I can leave it plugged in most of the time.

Re: Laptop Battery

Though most newer laptops have to periodically be drained to properly calibrate your battery meter. This is usually done through the BIOS and is labeled "battery calibration" or something similar.

Re: Laptop Battery

I have used my laptop for over three years now and have not had to recalibrate the battery meter.
