Regardless of what symptoms you`re noticing, the battery light is telling you a simple truth: you have battery problems, and your car isn`t getting enough current from the battery to operate correctly. That means it`s time to take action, starting with some simple maintenance.
If your 2012 Chevy Equinox battery warning light comes on while driving, be courageous to turn off your accessories, so the battery doesn`t eject further. The warning light usually means that the alternator isn`t working subsequently meaning you are operating solely on battery power.
Most modern vehicles have a dashboard warning light, typically in the shape of a car battery, that illuminates when the battery is not being reloaded properly or when it has an internal problem.
Your Chevy Equinox battery will typically last between 3 to 5 years, but that can vary heavily depending on weather conditions battery size, type of battery, and driving habits.
It is unsafe to drive with your car battery light on. Issues that activate your car battery light, like a defective battery or faulty alternator, can cause your car to lose power. In these instances, your car won`t operate as it normally would.
Low power mode reduces the amount of juice your device needs, so it`s not quite running on all cylinders. It works in more or less the same way whether you`re on an iPhone or an Android phone. Screen brightness is a big battery drain, and low power mode will dim your display accordingly.
Similarly, both iPhones running iOS 9 and later and Android phones running Android 6.0 Marshmallow include a low-power mode (sometimes called battery-saver mode) that significantly reduces the phone`s power usage by disabling power-hogging features.
In numbers, dark mode on an OLED smartphone is likely to save only 3 to 9 per cent of power as compared to a regular mode. These findings, however, apply to a phone`s use at 30 to 50 per cent of brightness, usually the range followed by an auto-brightness setting.
Measure your Equinox`s battery while the engine is off: After you turn the multimeter on, connect the red probe to the positive terminal (+) of the battery, which is usually marked in red color too, and then connect the black probe to the negative terminal (-).

Though turning on Low Power Mode permanently is an experiment you might want to try, if you find that you need to keep Low Power Mode on all the time to get decent iPhone battery performance, it`s very possible that your battery could be degraded or have other problems.

Keep getting Battery saver mode on my message screen and i replaced the battery like the dealer said.. message came back on?
ANSWER : Hello. A battery saver mode light can sometimes be set off by an issue with the battery, but it is also often set off if a problem occurs with the alternator, such as low or excessive output from a failed voltage regulator.

I would check the alternator to make sure that it is in proper functioning order, as an alternator issue can not only cause problems with the vehicle, it could also cause damage to the battery.

If you’d like to get this repaired, feel free to contact a certified mechanic who can diagnose the cause of the battery light firsthand and replace the alternator if necessary.

My battery saver active message came up on my car does this mean I need a battery or no?
ANSWER : Hi there. On a Hybrid vehicle, The Battery Saver Active message can appear on your driver information center (DIC) from time to time. In most cases, when the DIC displays this alert, that means that your battery has a low charge, and your vehicle is shutting off certain systems that may drain the battery of life.This doesn’t always mean that the battery needs to be replaced, but more likely that it simply needs to be fully charged.

How can I remove the message "service the battery charging system?"
ANSWER : Hi there:

If you’ve recently had major work done to your Chevrolet Equinox, it’s always a good idea to have the ECU reprogrammed or updated so it can monitor those changes; especially if any aftermarket parts were used. However, the service message is typically not fixed by reprogramming the ECU. In most cases, it’s best to start by having a professional mobile mechanic complete a service light is on inspection, which will allow them to download and remove any error codes stored in the ECU. The resetting of the ECU is typically done by a dealership for security reasons.

Battery light flashing at low rpm basically at idle my battery light flashes
ANSWER : Hi There,
You may have a failing voltage regulator that could be allowing the alternator to fluctuate too much resulting in the battery never maintaining a consistent charge as it is designed to. The voltage regulator is a unit that regulates the charging of the battery by the alternator. If the charging ability of the alternator is not maintained, this may cause a fluctuation in the power as you have described. In other cases it may result in the alternator not supplying enough power to the battery, resulting in undercharging the battery or not charging it at all. I would recommend having an expert from YourMechanic come to your location to diagnose your vehicle’s charging system.

Went got a test at Autozone for alternator, she stated everything test normal but battery voltage is too low? What does that mean?
ANSWER : Hello. This could mean the alternator is not charging the battery high enough or the battery will not accept and hold a charge. You may need to replace the battery first, then recheck the alternator charging system for proper operation. If you need help, an expert from YourMechanic can come to your home or office to inspect why your battery does not hold a charge and replace the alternator if necessary.

My Volvo XC 60 went into low power saver mode and the battery was already low what does this mean?
ANSWER : It sounds like you may have a weak battery, a failing voltage regulator or failing alternator. As you may know, the alternator charges the battery while the engine runs by generating amperage and recharging the battery while the engine turns the alternator pulley. The voltage regulator is a unit that regulates the charging of the battery by the alternator and maintaining a certain amperage while the engine runs. When the alternator is not working properly, this may result in the battery quickly losing charge and the car losing all power. You may also notice a whining sound as a result of the bearings inside the alternator begin to fail. I would recommend having an expert from YourMechanic come to your location to diagnose and inspect your charging system.

Battery light stays on and overnight battery drain. 2006 Land Rover LR3
ANSWER : Hi there – yes, something is going on here that’s draining your battery. Perhaps the pressure of the engine wash dislodged wiring which has shorted, or there was a chemical reaction to the cleaning solution that caused electrical damage in the alternator or voltage regulator. These componnents can be checked off of the vehicle. Vehicle wiring can be diagnosed by connecting an ammeter to the positive (red) battery cable, observe the current drain (likely less than 1 amp), then, one at a time, remove each fuse, check to see if the current drain has dropped to near 0, then reinsert the fuse. This process should identify the faulty circuit in most cases. The specific components on that circuit can then be checked for current drain problems. A professional mechanic, like YourMechanic, can come to your location, and perform this procedure for you, and replace/repair the failing component.
