![]() I think batteries might generally be safer nowadays, but I *still* think of my uncle whenever I have to deal with one of them. You had to look hard to notice the scars, but one of his ears was shrunken and noticeably thinner than the other one. Years ago, I’m guessing around 1950, an uncle had a battery explode in his face while helping a neighbor with a car repair. I don’t fool around with batteries without wearing eye protection. And double-check to make sure the terminals are oriented the same as the dead battery. Not sure if the 2018 has those, but a picture would’ve shown that.įor replacement battery, especially if living in a cold-weather area, best to get the same CCA (cold-cranking amp) rating. Some vehicles have structural cross-members running over the top of their batteries that have to be removed first. I’m assuming the 2018 is similar to my 2011 (?) - you remove the engine cover (one 10 mm Bolt then yank it off the one or two studs it’s snapped down onto), then the computer sits atop the battery, so just a bolt or two there and gently push it aside, then remove the POS and NEG terminals, unbolt the “hold down” mechanism (typically a block at the “foot” of the battery), and lift the battery up and out? I realize maybe you’re not a mechanic, but you could’ve taken your engine cover off (if it even has one), and snapped a picture or two for him. So don't worry about it, if you are concerned you can have the dealership check the charge system but I wouldn't sweat it.Click to expand.Even funnier then : why didn’t *you* help the OP out? You own *two* of these vehicles. I also learned the car has an unintended battery monitor. My inputting something after crank, the display system detected the DC voltage was now to snuff after cold crank so the display turned on. I realized that there was an under-voltage lock-out circuit to protect the display system. At other times I will see 14.1, which is what I would consider normal charging voltage. Yesterday I drove 50 miles and it was at 15.3 the whole time. ![]() When the new battery was put in no more display issues ever since. I noticed during a couple of recent trips in my 2017 LT that the voltage that is displayed on the DIC can be as high as 15.3 at times. 48H6) DieHard Gold - Battery, Group Size H5, 650. Before it was replaced I had the store load test it, it failed. Battery for Your 2016 Chevrolet Equinox DieHard Gold - Battery, Group Size H6, 730 CCA (Part No. I thought "this might be the battery going bad", I took a look at the battery and saw there was crack in the case near the positive terminal and leaking acid. As time went by the 'off at crank" problem was more common but always the display would snap on if you changed it's state. ![]() It happened when I was in the car but as soon as I did anything that would involve the display, say increase the fan speed, change radio station (this display is a glorified LCD that is multi-function), the display snapped immediately on. I though "oh great, that's gonna cost some $$". old, she told me the center display would just not come on occasionally when she cranked it. When my wife's 2010 'Nox was around 5 yrs. An interesting story about how well they work: I design power management chips and it's in many of the power supply chips on board and also at a system level of the individual sub-systems. Equinox - 2016 Equinox LT Electrical Issues (Service Battery Charging System) - I am having issues with my 2016 Chevy Equinox LT (47K miles, purchased used). These circuits are designed with over-voltage and under-voltage protection. I would not worry about an over voltage condition. In older systems it just would charge all the time but with modern power management system the designers can monitor the battery charge more precisely. ![]() It must be the charging circuit monitoring the battery and topping it off in sporadic fashion, perhaps to keep the battery life as long as possible. Flip open the plastic cover over the positive +. I can never tell why sometimes the voltage is at 14V or higher for long stretches, sometimes it's 12.3V for long stretches. The 12V battery is situated behind the electrical fuse box and in front of the coolant reservoir bottle. I've seen voltages like this in my car and the variations Campb292 sees too.
