Bullet proof, yes, precise, not quite... If a battery is charged up to
gassing every time and floated there, the voltage is above 13.6, more
like 14.6. A good 12 lead acid battery only needs to be floated at
14.200 volts for long life. Any more and it looses water by
electrolysis. Any less and it looses capacity by not being fully
charged. The SAE standards give a greater tolerance, but they cause
unwanted battery destruction.
