NICE TOOL. EASY TO READ IN DAYLIGHT LOOKING THREW THE WINDOW AND AT NIGHT. SEEMS ACCURATE AND SWIVEL FEATURE IS ALSO NICE.

I picked one of these up at a Wal-Mart in the Birmingham, Alabama, area about three months ago for $15.47 (plus 10% sales tax). I've used it in two different vehicles. It works like a champ. The Chevy S-10 truck shows a charging rate of about 14 volts and the Chrysler Town & Country van shows about 13.2 volts. The backlight works fine. I've had no issues with this device and I do recommended as a *simple* way to monitor your battery/alternator output.

I bought the voltage monitor and it works very well. I want to say that
the screen protective laminate, now has a small tab, and it is very easy
to remove. This comment is made to previous complaints regarding the
protective laminate removal. I would recommend this item, if you want to monitor your battery charge and/or if you have a power pack.

I have purchased two of these monitors. I bought the first one to monitor the battery on my van. I was so impressed with it that I bought a second one to monitor my Jump N Carry 660 jump start battery. Great tool!

This device gives a constant, backlit readout of battery voltage, together with color-coded info lights to help the inexperienced figure out whether those readings are good or bad. Sturdy, well-designed, and useful for basic battery and charging-system checking/monitoring.
