Battery Tender Voltage Indicator for Easy-to-Use Accurate 12V Battery Testing - Easily Track 12V Battery Voltage Using LCD Display with LED Charge Indicator - 081-0157

Worked as discribed. Easy to use makes it easy to check the battery with out taking seat off

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.

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.

Small Accurate Easy to use

I have a restored car that I just don't drive very often... but often enough to leave the battery connected. I connected this Battery Tender LCD Voltage Display to a Battery Tender Quick Disconnect cable with ring posts and attached the cable to the posts on my battery. The cable is long enough to stretch out about 6 inches in front of the battery and the monitor lies on top of the coilover tower. Now, whenever I want to check the level of my battery, all I have to do is press a button, and I know immediately whether my battery will start the car, or if it needs a charge. The Voltage Display has both red yellow and green LEDs indicating the general state of the battery, and the LCD display shows me the exact voltage output. Once I start the car up, I can also see that the alternator is putting out a voltage of about 14.2 volts, so I can tell it's charging the battery. Great little tool, handy to have permanently in the engine bay. This isn't exactly on point, but I also bought an Optima Yellow Top Deep Cycle battery which enables me to go a bit longer between charges if I happen to forget. I know that's not the typical use for the yellowtop… but the deep cycle function is perfect for this situation because when I do get busy and forget to check it, the battery voltage can drop well below what would normally be catastrophic, yet I can still recharge the battery. Last time, the voltage dropped to 4.5 volts. In a regular starting battery, anything below about 11.9 volts would be considered completely discharged, and 10.5 volts would render the battery 'dead' and NOT re-chargeable. I know, because I've bought several batteries over the last few years. (Although there is a way to bring a completely dead battery back to life in some cases... Google it.) The final entry in my battery setup is the thing that drains the battery in the first place. Because the car is now an expensive property, I installed a VIPER GPS-enabled remote starter /alarm system. The Viper app has a setting that will alert me when the battery gets low. (Low by common starter battery standards, not deep cycle). So when my iPhone starts honking at me, I know its time to charge that baby up. Problem solved.

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.

Purchase this for my motorcycle cruiser and it works well to check battery life and monitor battery power

es lo que es! Funcionamiento correcto

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 .

Misura con valori esatti la batteria,le dimensioni sono piccole,lo si puo' portare e mettere ovunque. La consegna e' puntuale,che dire?Ottimo acquisto!!!

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.
