Welcome to a laptop battery specialist of the Lenovo Laptop Battery
The carbon fibre construction, combined with solid state storage, means that the X1 Carbon can withstand accidental knocks and drops better than most other Ultrabooks. Meanwhile, its spill resistant keyboard and weep holes allow it to survive moderate-to-substantial liquid mishaps.
Apart from that toughness, it's an Ultrabook with a very good keyboard, plenty of processing power and, dare we say it, good looks. Some compromises have been made in regards to onboard connectivity, but compensation is provided in the form of supplied dongles for VGA and Ethernet. Built in to the base are two USB ports (one which is USB 3.0 and one which is USB 2.0), a full-sized SD card slot with battery suc as Lenovo 57Y6528 Battery , Lenovo FRU 42T4585 Battery , Lenovo L08L6C02 Battery , Lenovo 3000 G430 Battery , Lenovo 3000 G530 Battery , Lenovo IdeaPad Z360 Battery , Lenovo 51J0500 Battery , Lenovo FRU 42T4801 Battery , Lenovo FRU 42T4819 Battery , Lenovo ThinkPad W510 Battery , Lenovo ThinkPad SL510 Battery , Lenovo ThinkPad SL410 Battery , a combination microphone and headphone port, a mini-DisplayPort and an externally-accessible SIM card slot (for the integrated mobile broadband in our test model).
