I wouldn't use them again
I ordered what was advertised as a genuine DELL battery for my laptop. The battery took 15 days to arrive as (despite the name) the company is based in China and does not apparently have a UK office. I installed the battery however, although the condition showed as healthy, the machine constantly crashed when switched on unless it was plugged in to the charger. I have no way of testing the battery so advised the company of the issue. They offered me a 10% refund and suggested I could sell the battery locally or said that I could return it to an address in China at my own cost. I blame myself for not checking before ordering but I took from the name that the company was UK based, my mistake! Needless to say I will never deal with this company again and would suggest others think very carefully before using them.
