Wondering what to do if the seller HAS tampered with the battery gauge, I went looking for alternate methods to check. It seems these apps allow you to look at the health of each battery on an android device. Doing that would allow you to see if a given battery in the pack has become especially weak or defective.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
