6. The Problem May Not be Your Vehicle's Battery

On that fateful morning when you turn the key and your Subaru won't start, your mind will probably go to the battery first. It may well be the case that the battery is to blame, but it might be something else. For instance, what seems like a dead battery could be a bad starter. Or, there might be something else that has run down an otherwise good battery.

5. Alternator

The alternator is the part on your vehicle that generates power to run electrical components and keep the battery charged. Inside the alternator, there are brushes that will wear out over time. If you can get your vehicle running, simply putting a voltmeter on the battery can tell you if the alternator is working. The reading should be around 13 or 14 volts. Much more or less is a good indication that the alternator isn't working properly.

4. Corrosion

A battery that won't start your car may not be dead. It could be that the connections aren't secure, and corrosion is a common cause of poor battery connections. If you look at the battery and there's a crusty mess around the terminals or wires, cleaning the connections with a mixture of baking soda and hot water could solve the problem. For excessive corrosion, you may need to have the battery connections replaced.

3. It's Cold Out

This isn't all that common here in the California Bay Area, but exceptionally cold temperatures are one of the most common reasons for older car batteries to finally give up. If you find yourself in a particularly cold environment and your car won't start, it could be an indication that your battery is near the end of its service life.

2. Battery is Old

As we mentioned in the beginning of this page, no battery will last forever. Aside from the new all electric vehicles, automotive batteries are typically good for around four to six years. Several factors determine how long a battery will last, but eventually it will need to be replaced. Regular battery inspections at an authorized service center is the best way to catch a dying battery before it leaves you stranded.

1. Left Something on in Your Vehicle

This is one of those things that most of us can relate to. You may have dropped your cell phone between the seat and switched the dome light to always being on, or you were in a hurry and didn't catch the beeping that told you the headlights were still on. Whatever the case, leaving something on for a while in your ride is almost certain to leave it with a dead battery.
