Battery Charger & Alternator Checker (5) In Stock Now

First, re-charge that pesky flat battery, then start up the engine and use the alternator checker to see whether your battery is getting charged properly. Works with all main types of vehicle battery, including motorbikes and oldies with 6V batteries. It's only little, so it won't start the vehicle on its own; you'll need a few hours to charge the battery first.
