Which temperature does a discharged battery freeze at?

  • A.Zero degrees Celsius in every case, which is the freezing point of the water that forms the bulk of the electrolyte
  • B.A much higher temperature than a charged one
  • C.The same temperature as a charged battery, since the freezing point is determined by the water content alone
  • D.A lower temperature

Answer: B

A charged battery resists freezing to around minus sixty degrees, while a discharged one freezes near minus ten because the acid has entered the plates. A frozen battery cracks its case and is destroyed, which is why winter charge matters. Working the distinction through on a single concrete case fixes it more firmly than any rule of thumb. Naming what changes and what stays the same is the reliable route through questions of this shape. The quantity that varies and the quantity that does not are worth naming before any substitution is attempted.
