STD, AGM and GEL 6V and 12V lead-acid batteries used for engine start & deep cycle applications. (Link: Learn here about batteries, this will be at www.optimate1.com/batteries).
For 6V batteries from 12Ah to 192 Ah for 24-7 battery maintenance. Can recharge batteries up to 96Ah within 24hours.
For 12V batteries from 8,5Ah to 134 Ah for 24-7 battery maintenance. Can recharge batteries up to 67Ah within 24hours.

The time required for the OptiMate™5 to complete a charge on a flat but not severely discharged and otherwise undamaged battery is roughly equal to 1/3 the battery’s Ah rating, so a 60Ah battery should take no more than about 20-25 hours to progress to the Maintenance charge cycle. Deep-discharged batteries may take significantly longer.

The OPTIMIZE mode starts when the voltage has reached 7.2V / 14.4V for the first time during CHARGE mode.

Selection of the 6V or 12V charge program is done by pushing the select touch button. Disconnect the charger from the battery and hold down the button for 3 seconds to switch the program.

Yes, if the battery Voltage does not match the Voltage charge program, the OptiMate 5 6V/12V will not charge.
