If I install new backup batteries in the control cabinet of an S4 M94A, how low have do they have to be powered before I can cut the power (for approximately one minute) and to be sure that there will be no memory loss?

The manual does a mention that the voltage must not be less than 2.7V and voltage ideal is 3.6V . Normally Lithium battery is not rechargeable then if it has not the right voltage is necessary to replace it. The right measure is done when, turn off the robot and take a measure in the X81 and X82 connectors on the backplane.
