  • nom 12.8v
    15Ahr 0.2C
    charge voltage: 14.6 +/- 0.2V
        ie. "fully charged" = 14.6v
    charge current: 3.2A
    max charge current: 7.5A
    max continuous load: 15A
    max pulse load: 40A
  • a single cell is 3.2v
    so this 12.8v battery has 4 cells
  • some sources say you can discharge down to 2.5 v/cell
    which is 10.0v for this battery
    which is about (12.8 - 10)/12.8 = 21% discharge
        ie. "fully discharged" = 10.0v
  • other sources say you can go as deep as 80% discharge without damage
