Re: (ET) Battery bad lot? Open ?

["JohnR" <reinharj frontiernet net>]

If Open inter cell connector, would not a voltmeter show ZERO volts ?
NO current could flow, if there was an open connection between adjacent 
cells.

If one cell was shorted, but the others semi OK, you would see the sum - 
approx 2 volts per cell, of the good cells - or approx 4 volts, as was 
reported initially.

A load tester is always interesting also - just to see if the other two 
cells drop quickly ... but, with one dead cell, who cares ... as other post 
said ... time to recycle the battery !
