Perfect for checking batter voltage
Excellent unit for checking the battery voltage with the Deltran quick connect in have installed on my motorhome chassis battery. Much more handy than using a multi-meter.

Works great and just plug into the battery tender and it works. Lets you know the battery voltage and the charging voltage when you increase the rpms.

GREAT MUST HAVE ITEM
This is a must have item for anyone who already has a battery tender installed or who is buying one now. Works as described and will show via the digital readout in numbers of your battery's state of charge and when your engine is running of how much your alternator is charging it or not. Which is important for most of us with regular motorcycles since only a few m/c's like full dress Harleys & Honda Goldwings types come with dash mounted voltmeters from the factory, and the rest of US don't want to be stuck on the road or highway due to a dead discharged battery because they didn't know their charging system failed earlier before they left home.

Helpful Diagnostic Tool
I got this in conjunction with a larger project; installing a second battery in my truck. The battery isolator I used was supposed to regulate charging from a range roughly ~11.5-14.5VDC. So I wired in a pigtail to plug this indicator into, and I’m happy to say the indicator and the isolator agreed on the operating range. Occasionally I plug it to monitor the battery health. It’s relatively inexpensive and compact.

Great gadget
I bought this to replace my old one. This device is good to help monitor your battery's health. Easy to use if you have the pigtail on your motorcycle battery.

Works as it should.
Very accurate, I double checked the reading with 2 other volt meters I have. I'm happy with this little gauge, it's small enough to leave in my windshield bag to double check voltage of my motorcycle battery on a trip.

This is spot-on and just what you need to see your battery volts. It fits and works very well on my 2013 HD sportster. Handy to place under seat or carry in jacket pocket .

Me pareció muy funcional, como revisar el aire de las llantas siempre es bueno conocer el estado de tu batería, y si es necesario recargar con el tender, antes de tus viajes.

This tool is a excellent addition for checking the battery's strength on hard to reach power sports batteries. It's affordable, convenient, easy to use. A needed accessory.
