One of only two products to offer both 6V and 12V charging, the Accumate equalled the CTEK in picking up our battery at 7.6V. It comes with a plug-in battery lead, and the simple display includes three LEDs, which indicate full, charging and incorrect polarity. This unit revived and maintained correctly, with power rates varying from 0.72A to 1.25A. Light, versatile and easy to use, it pips the Airflow to our Recommended award.
