-[* black] At last we carve out the (mightily adhered) 5- cell battery.
- [* black] Not to beat a dead horse, but for a "Pro"-level machine, we're a little disappointed it'll be ''this'' hard just to swap out a battery—which eventually, inevitably, you ''will'' have to do.
-[* red] The attached battery board hosts a Texas Instruments IC: BQ20Z451 (a possible variant of the [http://www.ti.com/product/BQ20Z45-R1|BQ20Z45-R1|new_window=true] SBS-compliant gas gauge and protection IC)
-[* icon_note] And of course, those battery specs: 11.41 V, 49.2 Wh, and 4314 mAh.
-[* black] So what about the weight? The[guide|72415|"Escape Edition" MacBook Pro's 54.5 Wh battery|stepid=144793|new_window=true] weighed 235 grams, while this slightly smaller 49.2 Wh battery weighs just 197 grams.
-[* icon_reminder] That probably partly accounts for why this machine weighs a bit less than its sibling. Meanwhile, the battery itself seems to pack proportionally more capacity to weight.

+[* red] The battery board hosts a TI BQ20Z451 (a possible variant of the [http://www.ti.com/product/BQ20Z45-R1|BQ20Z45-R1|new_window=true] line seen in MacBook Pros forever)
+[* black] Listing a 49.2 Wh capacity this battery seems a little piddly compared to the [guide|72415|Function Key edition|stepid=144793|new_window=true]'s 54.5 Wh, especially considering it's driving a lot more functionality (pun intended).
+[* black] Dotting our i's we slapped these batteries on a scale: the Function Key-equipped MacBook Pro battery weighed in at 235 grams, while this battery weighs just 197 grams.
+ [* icon_note] The weight disparity probably helps account for a lighter Touch Bar edition, but the battery seems to rate more watt hours than the decrease in weight would suggest.
