A surprisingly good battery, considering it’s from Halfords’ standard range. A night in the freezer still left the battery able to give five no-nonsense starts, and our part discharged cranking test showed equal vigour too – despite a relatively average 360 cranking amps rating. Even the bulb test resulted in a very impressive 315 minutes.
