Bob - when new Lidl plugged in, immediately said '6.1V' and appeared on lowest block on the display. Was on 6.3 after 3 or 4 hours, so I think that the other unit must be defunct - and binnable.
(I wonder if a slight break in the wire to the croc clip could be responsible for it triggering off at too low a voltage?)
For anyone interested, Accumate sent me back this to an email enquiry about the detail of the stages. Posting in case it gives anything more than Timothy's post:
"The AccuMate 6/12 is a multistage 1.2A charger which operates has Bulk (constant current), absorption (constant voltage @ 2.4V/cell) and float charge (constant voltage @ 2.27V/cell). The switching point from absorption and float charge is set to 200mA. The charger will revert from float charge to absorption should the battery require more than 200mA. The charger also monitors the ambient temperature and makes adjustments to the bulk, absorption and float charge voltages.
We also supply a more advanced charger which has a 6V functionality, the OptiMate 5 Voltmatic™. In addition to the recharge and maintenance functionality of the AccuMate model, the 5 Voltmatic has the ability to access battery condition and then offer the charge mode best suited to its needs. The OptiMate 5 will also perform regular testing during the maintenance stages and report if the battery"
