Self discharge is the loss of stored charge

  • A.through the load during normal discharge
  • B.in the inverter between battery and grid
  • C.through the cooling system of the pack
  • D.while the battery stands with no load connected

Answer: D

Correct answer: while the battery stands with no load connected

Self discharge is the loss of charge to internal side reactions when nothing is drawing current. Lithium ion loses a few per cent a month, lead acid rather more, and both rates rise sharply with temperature. It matters for standby duties and for anything left unused for long periods, and it is one reason no electrochemical store is suitable for seasonal storage.
