Halfords Advanced Electronic Battery Charger

Smart technology has blown into the Halfords range with this powerhouse that packs a hefty 9A punch. Although it’s quite bulky, it’s not especially heavy, and the large digital display usefully shows the battery voltage. The impressive nine-stage system goes from desulphation to maintenance on batteries up to 200Ah, and its insulated clips are absolutely massive. Sadly, they’re 

on the end of really short leads, with no permanent connection adaptor and, more unusually, it wouldn’t charge below 4V.
