So I have two questions: when they say don't run down the battery to below 12.1, that means the resting voltage, right?
And second, is there an accurate correlation between working voltage and resting voltage? For example, if the battery reads 12.2 while under load, does that necessarily correspond to (let's say) 12.4 when resting?
To the first question: YES it means resting
To the 2nd.. YES but the correlation is specifit to both the battery and the day of the test..
That is a battery that looses say 0.1 volt under a given load TODAY,, Well in a month may loose 0.2
It is a function of the internal resistance of the battery which increases as the battery ages..
