Stop-Start Not Ready Battery Charging; Must Read.

Stop-Start Not Ready Battery Charging; Must Read.

If you see this message on your car’s computer, there is no need to worry as it is just a warning message that your battery is not charging up. 

A stop-start, not ready battery charging may be caused by various issues. The most common cause is a loose or disconnected wire. 

If you are unsure, the first thing to do is make sure that your engine is running and the battery has power. 

Next, ensure the speed control wires are connected to their respective connectors, check how much power leads from the alternator, and ensure it engages correctly with the engine wire.

 In addition, make sure there are no obstructions in your fuel line, which could lead to an improper fuel supply which would also cause the inconsistent performance of your vehicle when starting up or stopping and poor acceleration and deceleration at slow speeds. 

Another common cause is the ignition module itself. 

  • Disconnect one spark plug wire at a time and check how long it takes your engine to start up with only one plug wire connected. If it takes less than 10 seconds, this indicates an issue with your ignition module, and you likely need a replacement.
  • To install a new ignition module, disconnect your old one from its socket and install a new one by connecting it to its socket and reconnecting all wires to their respective connectors.
  • If you are still unsure that the issue is with your ignition module, please take it to a mechanic so they can properly diagnose the problem and replace the ignition module if it is faulty.

What Is Start/Stop Battery?

The start/stop battery is a rechargeable lithium-ion battery that provides electricity when the car’s engine is not on.

It powers many of your car’s electrical components, such as display screens, stereo systems, headlights, and interior lights. 

The primary function of a starting battery is to provide sufficient voltage to turn over an engine and start it. The function of a stop/traction battery is more complex and includes maintaining the supply of power for headlights and other accessories when an engine is not running.

When your Jeep says stop/start, not ready battery charging, what does it mean?

If your Jeep is on and you notice a message saying stop/start not ready battery charging, it means there’s a problem with the battery. 

There are a few different things that can cause this message. The battery most likely needs to be replaced, the alternator is not running, or there’s something wrong with the charging system. 

If you’re still unsure and it’s been at least three minutes since the message appeared, try starting your Jeep again and see if the problem goes away. 

If the problem is still happening, you should either:

1. Replace the battery

2. Replace the alternator

3. Replace the charging system and cables

Suppose your Jeep doesn’t start when it’s not supposed to; push down on the Jeep’s gas pedal with your knee while you’re trying to start it. If it still doesn’t start, then your Jeep most likely has a bad battery. 

To replace your battery, you will need to remove the following panels: engine cover, front fender well cover, and hood from around the bottom of your Jeep.

Why Is Your Battery Does Not Charging?

It’s most likely that the battery does not charge because the charging system has been damaged by water. You should bring your Jeep in for repair or replacement as soon as possible. 

If you do not, the battery will eventually overheat and rupture, causing damage to other systems and components of your vehicle. 

The battery is one of the essential components in your car, and it’s essential to ensure that it’s working correctly. If you cannot get the battery to charge, it needs to be replaced or repaired immediately.

Signs That Your Battery Is Bad

  • The battery gauge on the dash stays low with the engine running and does not go up when the engine is turned off.
  • During engine operation, voltage drops significantly under load (clicking of high beams, AC, etc.) during engine operation.
  • Cranks but does not start or cranks just a few seconds and then stops.
  • The battery is visibly leaking.

If you are sure that water has not entered the battery, it may be that the battery’s internal voltage regulator has failed. Because this device is essentially an electronic circuit board, it can fail from heat or age. 

The best thing to do is to have your Jeep checked by a technician and see what’s causing your Jeep not to charge or start. 

There are several reasons why the Jeep Grand Cherokee battery won’t charge. The first is due to a bad battery or charging system.

This is easy to check because all you need to do is have your battery and charging system tested by a mechanic. 

It can easily be replaced if one is faulty, and your Jeep will start charging again. 

The second reason your Jeep Grand Cherokee will not charge may be from the alternator being damaged or faulty. It will no longer produce enough power for the battery to charge when this happens.

How Long Does It Take To Charge The Start/Stop Battery?

The answer is a few minutes. You can charge a car battery in 20 minutes for a full charge. The time it takes to start and stop an engine while charging depends on the size of the battery. 

When a load is placed on the battery, it drains power. If the load is lower than the battery, as in your typical car engine, start and stop the process, you can charge a battery pretty quickly. 

The lifespan of a car battery is mainly dependent on its usage. A battery may last from two to six years, depending on how often it is charged and discharged.

In general, a fully charged car battery will die after about 24 hours without use, at which point the vehicle’s alternator begins maintaining the charge. 

The lifespan of a car battery is also determined by its quality; poor quality batteries typically have a shorter lifespan than high-quality ones. 

Additionally, temperature and climate affect the life expectancy of a standard 12-volt lead-acid automotive battery: for example, extremely cold weather can drastically reduce the range between 15°F and -15°F.
