For sale is an OEM Dell rechargable lithium ion battery for laptops type 8N544 - rated 11.1v 6486mAH.I am the original owner, and was in the laptop I purchased my senior year of high school in 2003. It was something like an Inspiron 8500, the top tier one for that year. The battery is in good condition - my kids gutted the computer so all that was left any good was the battery.It is 23 years old, so the capacity has diminished, but it still charged and would work for a while. Because of the age of this, you are aware you are not buying a brand new battery, there are no returns accepted.
