What happens if you put a car battery the wrong way?
Connecting them the wrong way may cause damage onto the battery you want to charge. For one, this causes a reverse in the polarity of the car battery. it might even cause the battery to explode in some cases.
Why are car batteries around the wrong way?
Bear in mind that car batteries (lead/ acid) will degrade much quicker when they are constantly discharging (completely flat)/ charging and just sitting around. If the battery was ‘newish’ it’d pay to look after it more, but it could easily be buggered after a year of the type of use you have described… Mister X writes…
What happens when you hook up a car battery backwards?
When they put installed the battery, they hooked it up backwards and blew the main fuse. When the main fuse was replaced and I was driving off I noticed that the charging light was on, and the radio/clock was not working. Taking it back, they confirmed that the alternator was dead and replaced it (with me paying for it).
What to do if your car battery won’t start?
Also inspect the battery terminals and main cables for any signs of looseness / corrosion, and address as needed. If any doubt as to the condition of the battery, recommend removing it & bringing to a local Auto Parts store that has the proper testing equipment to get it checked out.
Can you move the battery from one car to another?
There are many battery configurations in regards to terminal position and post size and shape. You could extend positive lead to reach the terminal but it is not worth it as you want to keep moving battery from one car to another. Like the other bloke said get a battery charger. yeah, forget moving the battery all the time…
What happens if you connect a car battery the wrong way?
So the incidence of the wrongly connected battery rarely occurs because the cable will not be connected if the battery is backwards. However, when the battery died, the car owner had to replace it with the new one. If we replace it with the same type as before, the battery will not reverse.
What happens if you put a new battery on backwards?
New cars have a negative earth so reversing the battery would mean that the new car engine management computer would not function, and the ignition would not come on and the start relay would not function. The alternator diodes would not like being connected in reverse, and maybe cause the diodes to fail.
Also inspect the battery terminals and main cables for any signs of looseness / corrosion, and address as needed. If any doubt as to the condition of the battery, recommend removing it & bringing to a local Auto Parts store that has the proper testing equipment to get it checked out.
What happens if you start a car the wrong way?
Your car is equipped with a starter motor excited by permanent magnets (on newer cars). In this case the engine will turn the wrong way when cranked…It won’t start and it is also possible to already have damaged many things on that car. (On a very old car, a positive earth would be correct and it should start and run ok).
