How Can I Tell If My Car Battery Is About To Fail (Or Has Failed)?



There are a few telltale signs that your vehicle batter is about to fail.


Take a look at them:

You can run into many factors when dealing with a battery, but you can eliminate them one by one. if the starter motor crank slow, but the engine won't start. it's a possibility it could be your starter.

Tip: You can always check battery with a battery tester. if the test read 12V, you have a good battery so there's a chance it could be your Alternator or starter.


2. Sluggish Cranking Times


Cold weather reduces battery performance.

However, if no cold weather, and your engine still stutters before cranking, then you could have a weak battery, bad alternator or starter issues.


3. The Engine Starts then Dies Quickly


The engine will start, but instead of idling it dies quickly.

If this happens, you may only have enough charge to crank engine but not keep engine on.

Tip: this happens often to many people

what happens is the battery shuts off, causing a signal straight to the (ECM) engine control mod

ule, which causes the engine to die.
