hey there, My current battery on my Macbook Pro is now ready for replacement. It still will hold charge for about 2-3 hours of regular use, so I will be replacing it. But was wondering if there was an enclosure that the old battery could be put into to turn it into a battery power bank. If there was a way to make that work, it still holds a charge and could be used to extend the battery life of my mac and possibly even charge my phone as well. Does this exist? Thanks!
