8. BATTERY OPERATION
8.1 Monitoring
Discover AES reports to the Conext SCP and/or Combox as a battery monitor (BATTMON) device. The AES
batteries provide signicantly more accurate battery parameter readings than the inverters and charge
controllers are capable of.

The charging voltage during Balance phase is a dynamic value determined by the state of all connected AES
batteries. Voltage and current values may vary between system to system.
▲ NOTE
When charging with Conext systems, AES charging
voltages may be up to 2.88V higher than specied in
published Discover Charge Algorithms.
8.3 Battery Maintenance
Batteries should be carefully inspected on a regular basis in order to detect and correct potential problems
before they can do harm. This routine should be started when the batteries are rst received.
• Look for cracks in the case
• Check the battery, terminals and connections to make sure they are clean, free of dirt, uids and corrosion
• All battery cables and their connections should be tight, intact, and NOT broken or frayed
• Replace any damaged batteries
• Replace any damaged cables
• Check torque on terminal bolts
9. RECYCLING AND DISPOSAL
Advanced Energy Systems are recyclable and must be processed through a recognized recycling agency or
dealer. Please contact Discover or your servicing dealer for details.
