Review on 🔋 Innova 3721 Battery and Charging System Monitoring Device by Jeremy Romero

When it gets cold, my car battery is the first to fail. I started the car and drove it for several hours to recharge it. I have already ordered this product firstly to see if it works and secondly to see if it gives me an idea of the condition of my batteries. I restart the car and now plug it into the 12v socket and it says the battery is charging while I drive. Another cold night and a third jump turns me on, but now when I plug in my device I get a charging warning. After about 15 minutes of driving, I turn on the heating and now the device tells me that my battery is not charging. So I went straight to the dealer and I'm glad I did. The device gave me very accurate information and if I hadn't contacted the retailer I would have been in real trouble. My car was fine. My battery went from 640 CCA to 32 CCA and couldn't be recharged. It has 3 months left on its 3 year warranty so the seller kindly replaced my battery and extended the 3 year battery warranty. I now have a monitor for every car and I would be out on the road without it. This gave me the information I needed to know I had a battery issue that needed to be resolved asap. It has also saved me from being stuck in the cold waiting for service which could take hours during this pandemic. There are several such devices on the market, but I can assure you from my own experience that the INNOVA 3721 works flawlessly. It's also incredibly easy to understand.
