I have a mini (real ...) that does not run enough and whose battery eventually deteriorate from lack of activity. I was going to change again because the load did not take more than a week after a long immobilization. That's when I came across the CTEK MX 5.0 and there miracle, not only the battery has been recharged, but mostly it retains its charge again through the reconditioning system. It's really great. I recommend.
