Make Your Car Battery Last 10 Years So EASILY It Feels ILLEGAL

Your car battery died again after three years, and the guy at the counter told you that's just how long they last. It isn't. Most batteries don't die of old age. They get killed early by summer heat, short trips, dirty terminals and hidden drains that nobody ever checks. I'm Frank Decker. I spent 38 years as a mechanic, 15 in dealership service departments and 23 running my own shop in Dayton, Ohio. In this video I walk you through the 10 easy habits that got some of my customers nearly 10 years out of one battery. Most of them are free, and every one of them is something you can do in your own driveway. In this video: Why most batteries die years early, and the 3 things that really kill them The $1 baking soda trick for cleaning corroded terminals, and the right order to take the cables off Why a loose hold-down bracket can short a battery from the inside How short trips slowly starve your battery, and why idling in the driveway doesn't fix it Why summer heat kills batteries and winter just shows you the damage What to do right after a jump start so the battery actually recovers How a hidden drain killed 3 batteries in 4 years, and the drain test to ask any shop for Smart maintainer vs old trickle charger, and when to disconnect the negative cable for storage What your battery voltage really means at 12.6, 12.4 and 12.2, and why charged doesn't mean healthy The free load test most parts stores will do in 5 minutes How to check your alternator with a $15 meter Buying a new battery: date codes, AGM batteries and cold cranking amps No gimmicks, no miracle additives and no promise that every battery will last 10 years. Most give you 3 to 5. These are the habits I watched make the difference between a battery that quits at 3 years and one that keeps going at 7, 8 or even 10. How long did your last car battery last you? And if you've ever gotten one past 10 years, tell me what you did in the comments. I go through every single comment.
