What to do if your car battery is put in backwards?
If all the fuses and fuse links test good, check for spark at the plugs, make sure the fuel pump runs when you turn the key, and if you have a code reader, make sure the computer is alive and responding. Good luck and I hope no serious damage was done.
Can a battery be broken by connecting the wrong way?
Almost all consumer electronics have protection in place to prevent any damage when connecting the battery backwards. Companies know they can’t trust consumer to put the batteries in the correct orientation and it is usually cheaper for them to add the protection then it is to deal with support calls and returns.
What happens if you reverse both the batteries?
If you reverse both batteries the result may be worse: most likely the device will be damaged, esp. if it’s electronic. The batteries may survive without too much damage unless the reversal causes a short circuit. “esp. if it’s electronic” what else can you can you power batteries with that aren’t electronic? – Dean Dec 12 ’10 at 13:59
Can a stack of batteries be reverse biased?
Devices with five or more batteries in a stack could be reverse-biased if one connected the end batteries in one polarity and the inner batteries the other way, but that’s probably not a terribly common a scenario, and the properly-polarized batteries would help to impede the errant current. – supercat Feb 23 ’11 at 16:07
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 causes a battery to leak when left unattended?
A slow parasitic battery drain is common in many devices. It will slowly discharge the batteries until they’re ‘dead’. As a result, the batteries may eventually leak. A device that is left unattended for long periods of time (with the batteries installed) may drain down slowly and kill the batteries.
What happens if a car battery goes bad?
Ans: Depending on your car, the damage to your battery could be very high or very low. If it’s high, then you have no other options but to replace it with a new one. Q: Can cars run on batteries connected backward?
What can I do to prevent my battery from leaking?
And/Or, Remove the batteries from electronic devices that will not be used for a significant period of time. This will prevent a slow discharge of the batteries and therefore prevent leakage when the batteries get low or go dead. Dead or low batteries are more likely to leak.
