Review on 🔋 Enhance Battery Performance: Save A Battery 2120-S 12 Volt 2' SMART Battery Terminal Cable with LED Voltage Meter by Lamont Manjrekar

My cars don't drive much and every time you start the car you have to drive for some time to replace the charge used up when starting the engine so if you just break the fast drives every few days your battery will eventually fail, especially during the severe cold winter months, so I stick a smart cable out the front of the grill to see when the battery drops below its optimum charge level, and it's even easy to see a few meters, because only green is good, green and red together are a sign that your battery is not optimally charged. So all you have to do is plug in your charger/maintenance/air conditioner and it works by itself to maintain and condition your battery and it works. great because I switch between two vehicles when the voltage level in one of them starts to drop so they are necessary for little used or rarely used vehicles to keep you up to date without opening xy d and metering the voltage having to measure because the actual charger maintenance even tells you the current voltage going into the battery or the charge present and the smart cable is bridging the BC
