I mentioned that he could also disable security. So he would be

to insert the battery after you do batman-start because
batman-start disables the EC's charging system. Its stays disabled
until you do batman-stop or until you reset the EC.

Its a 2's compliment number. Negative values are normal. But you need
more than 1 reading. A single reading of the ACR doesn't tell you

Running bat-recover is unnecessary and for your battery basically
