Battery Specifications

• Nine 12.9 volt batteries connected in series provide approximately 116 volts at full charge.

Battery Capacity

• The GE AMX 4+ battery capacity can be measured by one of the following five methods. All capacities are measured after the AMX−4+ has been charged to the “CHARGE COMPLETE” state. Available capacity as stated applies only to new battery sets free of defective cells. Capacity may decrease as the battery nears the end of its useful life
