all I know is that this battery will fit HP/Compaq labtop. i have an HP Pavilion laptop, this battery work really well for me. I don't know what kind of laptop you have, but on the original battery, there is a note on the battery itself telling you what kind of replacement you can use in case you need one.
Thank you and good luck for your battery search.
More than an hour so far. However, the darn thing won't stay in. Doesn't fit right. I have it held in with clear packing tape. Good price on the battery but although it clicks in it falls out continuously.
