Rip it up and start again

By Anonymous - 04/05/2022 10:00

Today, I had to borrow my mom’s car to jump-start my battery-dead car. I got everything set up and it worked. Parked my mom’s car back into her spot, went into my car. And turned it off. Now I have to do it all again. FML

Unless you left your lights on and the engine off for a very long time or the car has not been run in a couple of weeks or more - Chances are if your battery is dead, it’s dead. While you can jump start a weak battery, once it’s on the decline it’s probably failed. You can jump start your car and go to your local car parts dealer and they will test and replace your battery - Usually for no extra charge over the battery price itself. Most of the time lead acid car batteries last about 3 years. First aid for automotive lead acid batteries: (1) Make sure the car is started and run at least 10 minutes once a week if you are no longer commuting. (2) Make sure to always turn your headlights off and shut the doors when you get wherever you are going. (3) If your battery connections are corroded or loose even a good battery will not crank the car or take a charge. The positive terminal is especially prone to corrosion. If you see visible corrosion as a “first aid” first rinse off the terminals with Diet Coke - The phosphoric acid dissolves the corrosion. Then wiggle and tighten the terminals so they now make a good connection. Later wipe up the mess around the battery terminals and spray the contacts with WD-40 to keep it from further corrosion. Lead Acid Battery safety notes: (1) Lead is a toxin, be careful to wash it off your hands and do not put hands or fingers in mouth until hands are cleaned. (2) The liquid in the battery itself is highly acidic. Fortunately most are sealed now. But if you crank over and over and over the battery can become hot enough to boil out. That is very dangerous. (3) The 12 Volts typically used in a automotive lead acid starting system will not shock you. You can touch it with your BARE hands. But if you short with a metallic object from the automotive frame or battery negative terminal to the battery positive terminal it can draw a lot of current and give you arcs and sparks - Do not do that! Take off rings, watches, bracelets while you work on the battery so you won’t get hurt from an accidental short circuit. By the way - I am an electronic engineer…

At least that’s something you can easily do.

Go to autozone and buy a new battery with your mom’s car

for next time your suppose to leave a car running for a little while after a jump to charge it. if still doesn't hold a charge get a new battery

Just drive your mom's car and tell her that your car is actually hers. If she gives you any pushback, start a discussion of senile dementia.
