Gear: LenovoThinkPad X220T, 52+ Battery, 19+ Battery Slice, X220 Tablet Sleeve.
The X220T comes with a Lenovo 52+ 6-cell battery. I got the slice along with the review unit. Today I'll go over some of the details about each battery.
52+ Battery (6-cell) Notes:
- It comes with the X220T.
- The battery goes "deeper" into the X220T's body (this came a bit dirty).
- It does not go the full width of the system leaving a gap for the power and vent.
- It adds an angle to the X220T which makes portrait note taking really weird.
- The battery can be used as a carrying handle.
- When in landscape mode the battery does give an elevation that is pleasant.
- I get an average of about 5 hours with my usage (about medium settings)
19+ Battery Slice (6-cell) Notes:
- I assume that I would get an extra 5 hours of battery life for around 10 hours of computing (it's a 6-cell and no I have not perform a test)
- Hardware wise there's a power port, battery meter, speaker holes, latch crease, accommodation for the 52+ battery, connector to laptop, drain holes, lock and release latches.
- No it won't give you a "flat" angle in portrait mode (it does however improve it)
- This is not a docking station
- It doesn't add a lot of "weight" to the X220T.
- You can use the slice without having the main 52+ battery
- I get much longer battery life with the X220T's 6-cell (about 5 hours) than with the X201T 8-cell (3 to 4 hours). Average battery life will change depending on many things including the amount of usage.
- No 9-cell battery in existence as far as I know.
- The ThinkPad UltraBase Series 3 is the docking station for the X220T.
I hope this answers some of your questions. Thanks to Andy for pushing for me to checkout the slice battery which has been sitting in the box since the "unbox" video.
