Lithium Polymer: 46% More Capacity, 0% More Weight
Today Apple is shipping lithium polymer batteries in all of its MacBook Pros. Only the original, white MacBook is offered with a removable battery. Most impressive are the capacities Apple is able to offer thanks to these new batteries.
The table below shows the old and new battery capacities:
|New Lithium Polymer Battery (Integrated)|| |
|Increase in Capacity|
|MacBook Pro 13-inch||58WHr||45WHr||29%|
|MacBook Pro 15-inch||73WHr||50WHr||46%|
|MacBook Pro 17-inch||95WHr||68WHr||40%|
Now there was no 13” MacBook Pro before, so I’m comparing to the old aluminum 13” MacBook. Also, the 17” MacBook Pro was the first and only unibody 17” MacBook Pro so the old battery I’m comparing it to was the previous generation 17” MBP battery.
73Whr?!? Holy crap
The biggest winner is the 15” MacBook Pro, it gains a 46% increase in battery capacity with zero increase in size or weight. The new 15” MacBook Pro is the same size and weight (5.5lbs) as the previous model, it just has a 46% larger battery. Did I mention it’s cheaper too?
