The LCD screen of the Equus 3721 will display the measured voltage and has a bar graph to show you battery charge level and also has a color coded LED which will allows you to see the battery charge status.

The battery monitor will also show the voltage value with .01 precision and that is more than enough for you to tell you the status of the battery. When you plug it into the cigarette lighter of the car it will automatically switch between “battery status monitoring” to “charging status monitoring” and if the engine is switched off it will go into battery status monitoring.

With the engine running you can quickly see the status of the battery with the LED light. You will see green for a normal functioning electrical system, amber where there is a marginal power loss and red if the battery is discharging.

By H.Wang:

The picture on Amazon site is not correct. This battery monitor shows the voltage value with .01 precision (or two digits after decimal point). That is far more then enought to tell the battery status. I put it in the car, it automatically switches between “battery status monitoring” and “charging status monitoring”. When the engine is stopped, it is in “battery status monitoring mode”, when engine is running, it will be in “charging status monitoring” mode.   Read More At Amazon.com

 

 

By J.B Syrett:

Seemingly just another auto gadget fortunately the Equus 3721 is more sophisticated than its ponderous description. A breeze to connect to any car’s 12 Volt electrical system. Simply push into the lighter socket or an auxiliary power outlet now found in many newer vehicles.

With the engine running the instrument constantly displays battery condition with an LED light; amber when marginal, red if the battery is discharging. A green light indicates a correctly functioning electrical system. All is well with both battery and, most importantly, the alternator.

The Equus is also an accurate voltmeter. Digital read-outs give exact voltage in the electrical system. Potential alternator problems or a failing battery will be indicated by below normal voltages, plus an amber or red light. Extra information is a battery icon graphically showing total battery charge. Tending towards erratic read-outs, and therefore unreliability, it is not the unit’s best feature.   Read More At Amazon.com
