At first glance this low cost D/C voltmeter looks like any other one available anywhere, however, on close inspection you will see it is not. Standard voltage probes only go to 14 volts and are unable to inform you if the advanced charging cycle is in progress or a system has failed and is overcharging your system. The extra two LEDs re preset to give more useful information than the very limited standard ones. This is a Sterling product and is not available anywhere else.
