Worked right out of the box, batteries not required. Tested it on a lithium rechargeable battery and it worked exactly as it should. It is just a glorified test light but the digital voltage readout will allow you to determine whether the right voltage is traveling through your circuit, just because you get a light to illuminate doesn't mean it's the right amount of voltage, so this will help you through the process of elimination to decide what to do next. I bought it specifically to find out if my coil circuits to the spark plugs are all good because it's throwing out a misfire code. Review: good price, topproduct!! - good price, topproduct!! ## Features - 【3-72V WIDER TESTING RANGE】 JASTIND premium automotive test light is upgraded to 3-72V voltage testing range, wider than most test lights on the market.
