Chapter 8 Operation
Note: The EBM will charge to 90% capacity in less than 3 hours. However, the batteries should be
allowed to charge for 48 hours after installation or long-term storage.
It is important to run a charge cycle of 48 hours to ensure the capacity and runtime is
synchronized. Two battery tests are performed during that portion of the ABM cycle, three
measurements are performed and will ensure there are no bad cells in the battery string.
The battery algorithm needs a known starting point for ABM functionality, battery test and the
estimated runtime to be reasonable. Charging the batteries for 48 hours ensures those
functions are set correctly and advised for any start-up to ensure the batteries are good and the
timers are setup correctly.
