Affordable, no-fuss battery tester with fuse and bulb checker. Tests AAA, AA, C, D (1.5V) & 9V batteries and indicates their power level on the easy-to-read, colour-coded analogue display. It checks bulbs and fuses, giving a 'good' or 'replace' indication, and will also test larger 1.5V button batteries like the LR-44. There is also a handy compartment to store spare fuses, bulbs and button cells. A must for every toolbox.
