Experienced mechanics share their insights in answering this question :
Hello. The alarm system must be able to draw power from the battery in order to work while the vehicle is off. Due to the recent after market installation, it is likely the vehicle’s battery and charging system have been comprised. Have you tried to jump start the vehicle? The battery may be dead. You are going to want to visually inspect the wiring connection for that new alarm system. Also verify the battery cables, battery ground, and connections to alternator are all clean, dry, and tight. You may simply have a bad connection or loose ground. The battery saver is likely stopping the vehicle from starting because there is not enough power to crank the engine. It wants to conserve what it’s got left and use it for the other components depending on it. Start by further resting the battery, alternator, and connections.
How to Identify and Fix Common car Problems ?

Hi there. The Battery Saver Active message can appear on your driver information center (DIC). 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.
An illuminated battery indicator can be caused by a number of issues, including: A loose or corroded battery cable. A problem with the alternator or voltage regulator. Damaged cells or plates inside the battery.
This indicates that the alternator is not working properly. What is this? The most common cause of this problem is an alternator failure. Alternators are responsible for charging batteries in cars and other vehicles, and when they fail they can cause all sorts of problems with your vehicle`s electrical system.
As you probably know, the battery saver mode will come on when there is a problem in the charging system. If the charging system isn`t working, with a new battery you can drive the car for several hours and a couple of dozen re-starts before the voltage gets low enough to cause a problem.
A blown fuse could be a cause of the battery light to come on. Excessive voltage in the electrical system can blow the fuse and prevent charging of the battery. A electrical technician can replace the fuse quickly and it an inexpensive fix.
The battery light on your car dashboard signals a charging problem with your car battery. If the light turns and stays on, it might be that your alternator isn`t generating enough voltage to charge it. Common causes can be a broken alternator belt, damaged battery cells or a failed alternator.
But if the alternator isn`t functioning properly and the battery dies, your car may eventually lose power and stall or completely shut off. So, can your battery die while the car is running? Absolutely. And oftentimes, this issue is caused by a combination of alternator and battery problems.
Some of the most common reasons for a car battery to die repeatedly include loose or corroded battery connections, persistent electrical drains, charging problems, constantly demanding more power than the alternator can provide, and even extreme weather.
When the battery current sensor fails, the vehicle will not charge correctly, leading to a DTC or a dead battery. Common signs of failure include: Irregular charging rates. Low battery voltage.
Battery Saver, Power Saving, or Power Saving Mode is a feature available on all Android devices that aims to limit power consumption, so that your battery lasts a little longer until you get to charge it again. When turned on, this feature can add another hour or two to how much your battery lasts.
No. There`s no risk to your phone`s battery when you use Battery Saver mode. In some ways, it may even extend the battery`s life as you aren`t constantly recharging it. Ultimately though, you don`t have to worry about it ruining the battery while using this battery-saving mode.
When the battery saver warning indicates that the battery voltage has dropped below and acceptable level and the vehicle is shutting off accessories to keep the vehicle running. If this light is seen the vehicles battery and charging system will need to be load tested.

ANSWER : Have the battery load tested in case it was short circuited. Reverse polarity, at the battery, in a 12 volt electrical system on a car can cause a variety of effects including damaging the alternator, diodes and the numerous microprocessors on a vehicle such as those in the powertrain control module (PCM). There are fuses, fusible links, circuit breakers, and many electronic components in many circuits that could have failed due to the reverse polarity. Inasmuch as the vehicle does not start, the simplest thing to do is diagnose the starting circuit first as, in the course of that diagnosis, other fundamental failures (for example if the PCM was fried) will come into view. If you want these steps performed by a certified Mechanic, dispatched by YourMechanic right to your location, please request an electrical diagnostic and the responding certified mechanic will get this resolved for you.

2005 Chrysler 300C changed battery and alternator. Car started, ran, and then battery light came on. Shut car off and wouldn’t start.
ANSWER : Hi. There is a couple of things that could be wrong here. The battery or alternator that was just installed could be defective. Theses parts need to be tested for proper operation. There also could be a fuse, fusible link, or wiring for the battery or charging system that is blown or broken causing the battery light to come on.
The codes that you have will cause the car to shut down, run rough, or not start at all. The crankshaft sensor and camshaft sensor should be replaced. I suggest having a certified technician from YourMechanic come diagnose the charging system and check engine codes to help you proceed with correct repairs.

ANSWER : Hi There,
You may have a failing voltage regulator that could be allowing the alternator to supply too much or too little amperage to the battery 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. When the voltage regulator is not working properly, this may result in the alternator allowing too much power to be delivered to the battery resulting in damaging wires and prematurely sometimes destroying the battery. A common sign of this is usually the acid inside the battery boiling causing the battery to swell. You may also smell a bit of smoke due to things potentially getting too hot. 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.

ANSWER : The battery should be load tested by a professional. Load testing can only be reliably performed on a fully charged battery. If the battery passes a load test be sure it is NOT a marginal pass in which case you should install a new battery to reduce diagnostic headaches. Batteries are a VERY important component in a car’s electrical system.
There is a 7.5 amp fuse that protects a battery sensor that is installed on the battery in late model Hondas. If that 7.5 amp fuse is blown, you will get a warning light pertaining to the battery and/or charging system. Check that fuse and, indeed, all fuses that might be electrically implicated in a charging system fault. If the battery passes a load test, or is new, and the fuse is intact, the cause behind the warning light will have to be determined as the warning light means there is definitely a problem. The fact that "a" mechanic is unable to "find" the problem obviously does not mean the problem does not exist. If the fuse or battery are not the issue, the service to request to get this resolved is an alternator/charging system diagnostic and if you request that service the responding certified mechanic from YourMechanic will test and diagnose the charging system and pinpoint the fault.

ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
When changing the car battery, do you "register" the battery to the car computer?
ANSWER : Hi there. Changing the battery has nothing to do with programming a battery. If the car was flat dead with a battery that lost all of the power because the dome light was on, then when jumped the vehicle will run fine. What may need programmed when the battery is replaced is the key fob. The key fob will lose programming to the computer as the vehicle computer is reset. However, if a 9 volt battery saver was put into a cigarette lighter and the car battery was removed, then the computer will not lose its memory and be just fine. If you need further assistance with your battery, then seek out a professional, such as one from Your Mechanic, to help you.
Water was spilled in the trunk which soaked the car battery. Car won’t start now. Does water destroy a car battery?
ANSWER : Hi, thanks for writing in about the concern with the BMW 320i. If the battery was submerged in water then it’s completely possible for the battery to short out and die. Your friend will need to have the battery replaced. Also be sure to get all of the water out of the trunk. Have a certified technician, like one from YourMechanic, help you guys out if you need assistance with replacing the battery. Good luck.
