I ordered a replacement battery for my Lenovo X1 carbon from AC Doctor Inc, it died in 6 months. I contacted AC Doctor INC, doubtful they would do anything. But THEY REPLACED MY 6 MONTH OLD BATTERY WITH A NEW ONE! These guys get 5 stars in my book! I would give them 10 stars if I could. They stand behind their products obviously! Thank you AC Doctor Inc, for being a great company!! Review: Great value, perfect match, easy to install. - The battery works great. It looks and fits like the OEM Dell battery - easy to install. It was packaged well and came charged at 90%. A screwdriver is included along with an extra screw. The battery health and wear seems to be reporting properly in HWiNFO.
