Dell Laptop replacement batteries?

[JohnnyBoxer]

Can anyone recommend a decent quality replacement battery from a reliable seller

Mine has died and Dell want £140 for an OEM replacement

 

[Monsieur]

I bought one several months ago via ebay - no idea which seller but the battery is working well and cost around the £40 mark

I've been buying from these http://www.laptopsandspares.com/ recently. if they don't have stock it usually takes 2 weeks to arrive but they keep you informed all the way and don't take any money till dispatch.
