Will battery from Early-2015 work in Mid-2014?

Hello,

I was just wondering if the batter from the Early-2015 MacBook Pro Retina 13" would fit the Mid-2014 model in order to extend its battery life?

Is this a good question?

The amount of difference between the batteries is not worth the amount of work and cost - Save your money.

I should point out the real difference is how the newer system manage having more run time is the logic improvements needing less power not the slight battery improvement.

Hey Dan ! Is it the same connector though ? I need to troubleshoot an early 2015 battery. Can I safely plug a mid 2014 battery in an early 2015 logic board? Thanks a lot !!
