How to keep good battery health

[Samuelsan2001]

As I understand it, a lithium battery is best stored at around 50% of full charge. Having recently moved from Lenovo Thinkpads to Mac, I was disappointed to find that Apple don't have a feature in Mac OS that allows you to manually stop the MacBook from charging its battery at 50%, or indeed any % except 100%.

My solution. I discovered by accident that the 12W Apple iPad charger (model A1401) provides exactly the right amount of power to run a MacBook in normal usage conditions, but without charging the battery. Problem solved. Unless someone can explain to me that this is somehow a bad idea?

Its not a bad idea as such, its just pointless, its a laptop use it as a laptop fully charge it and get 7- 10 hours out of it when travelling or away from a socket, leave it plugged in and fully charged when at home sometimes because its convenient. That's the point of a laptop convenience of computing when and where you need it worrying about battery longevity and ruining that convenience to maybe make your battery last a few extra months is just not worth the trade off. That simple really.
