One of the few batteries tested here to be priced under the £40 barrier, which makes its average performance in the test rather more acceptable. It managed 370 cranking amps to allow a start after the controlled partial discharge, and three starts from cold. It took over three-and-a-half hours for our bulb to go out, too, which is what we’d expect from a 43 AH rating.
