Notebooks Reputable 3rd party laptop battery vendors?

Got to get a couple of batteries for 2 small dell laptops that are now about 5 years old and their batteries don't seem to hold much of a charge anymore. Can anyone recommend a good supplier for batteries for laptops as Dell want £140 quid for one!

Thanks.

 

ebay mate? they wont be official as such, but will do the job!

 

Bought a third party battery from 7dayshop for my Dell D630 and it's fantastic, can last beyond 5 hours at a push!

Sold out on this model now unfortunately but they stock all sorts so it's worth checking out.

 

Just bought the battery can certainly use more than three hours, the battery's recommendation to purchase several well-known network shop online.

 

Have bought 2 batteries from Laptop Powerup on Ebay. Both came quite quickly and worked really well.
