Beware of Laptopartstore.co.uk
This is NOT based in the UK, they ship from China, takes 30 days!! or more so good bye refund, shockingly bad company to deal with, no email response at all, address is in the middle of a housing estate in Birmingham!! which does not exist.
You can't ship any batteries back to China without breaking transit rules. No tracking!!
I bought a Dell replacement
still in it's box... no help from PayPal. over £50 to ship back... if I could!!
