Review: ... this for a family member & it is working fine. Excellent - I bought this for a family member & it is working fine. Excellent product
Review: Works but misleading information 😕 - Battery arrived quickly and despite the part numbers not matching the original battery it still clicked in and works. The problem is in the write up it says "lasts as long as the original battery" or something similar, it doesn't 😕general use, bit Web, listening to music, moving files to NAS drive and it's flat in around 2.5hrs. If I switch off WiFi and use lan I can stretch it to just under 3hrs. My original battery got 4 - 6hrs depending on what I was doing. I emailed the seller and got "please refer to desertcart's community questions." Or as my mate puts it "we've got your money, get lost!". I've given it three stars as it does work, I might increase that if it's just the battery needing time to work in. There's plenty others out their that are cheaper and probably last just as long if not longer. 😐 Update: even with very little use, mainly half a hour the odd time every few months, the battery is always flat if left (turned off). It now needs charging everytime I turn the laptop on 😕Complete Junk playing on the Eco Green label to boost sales. My advice buy another brand 😉
