The MESSENGER observations and data from the two earlier Mariner 10 flybys are consistent enough to describe a dipolar field with an active electrical dynamo in which the magnetic field is produced by electrical currents flowing in an outer core of molten metal (more discussion and images from MESSENGER's January 2008 flyby).
Options include breath testing, skin pinprick, a stomach gastroscopy, an intestinal biopsy, stool analysis, skin sample analysis, electrical current testing, muscle testing methods, and more — and there is lots of controversy in the medical and nutrition community about which test is best.
Another problem is that new cars have much larger demands for electrical current, so batteries must produce more juice but with the same physical volume.
If the batteries are of unequal strength, the weaker battery will be damaged more severely from that experience than it would be from a short - circuit, though if the weaker battery properly tied to its vehicle's electrical system enough current might detour through the electrical system to reduce the damage sustained by the weaker battery.
