How to save from battery overcharge - Computers & Internet

im sure it maybe fine to leave on the charging base since the battery pack in it is managed by an onboard battery management chip that protects it from overcharging but if you wish to it is save to unplug it if you only wish to do so

Change the alternator

i would say pcm.these. are notorious for getting spiked from ignition sys.have ya had any perfomance problems in the past?

battery sat inside to long or was overcharged... not worth saving

Did the overcharge or voltage regulator problem go away with the new ECM in it? If so the transmission code.. (turbine speed sensor input) code is probably another problem that the Jeep has.. and the ECM will not fix that, but the input speed sensor that it may need is not very expensive.

Over charging could be the result of several things including:

Faulty Voltage Regulator
1. A car's battery will overcharge if the voltage regulator isn't working correctly. A voltage regulator is usually part of the alternator, and is used to keep a steady flow of voltage to the battery. If the voltage regulator is defective, it will send either too little or too much charge to the battery. If it sends too much, the car battery will overcharge. The voltage regulator is easily replaceable at an easily affordable price, sometimes for as little as twenty dollars, as of 2009.
Faulty Alternator
2. Sometimes the alternator itself can be at fault. The alternator is the device that converts the mechanical power of the engine into electrical power to charge the battery. When an alternator breaks, it usually stops creating electricity for the battery, which will then eventually die. However, if the wrong alternator is placed in the car, or if the alternator is running at the wrong pace, it will create too much energy for the car battery, causing it to overcharge. The alternator is another easily replaced part.
Incorrect Charger Use
3. If a battery charger is used to charge your battery outside of your car, improper use of the charger can result in overcharging. If a battery is placed on the charger too long, it can result in overcharging, and a significant decrease in your battery's lifespan and efficiency. This is why it is important to read about your specific battery and understand how long it needs to charge to be effective. Too much charge will lead to problems.
Faulty Battery Chargers
4. Sometimes chargers can be faulty. Their settings may be wired incorrectly, or the charges labeled incorrectly. As a result, your battery may be getting overcharged, even if you are carefully monitoring your charging. This is a problem that is hard to avoid, as manufacturing mistakes can happen anywhere, anytime without warning. It is a good idea to test your charger regularly to see if it is running correctly.
Heat
5. Extreme heat in the summer can also have an adverse effect on the car battery. If the battery has been previously overcharged, extreme heat can increase the problems caused by overcharging, and exacerbate any other problems with the battery. This problem can be hard to avoid if you live in a warm climate. The only real way to ensure safety against this problem is to avoid overcharge in the first place.

Check your settings for power save and power management. I suspect the battery has been overcharged and has lost most of its power. Only charge the batteries when they go flat otherwise they will suffer storage loss as you now have.

Hi and welcome to FixYa,

Almost always, overcharging would indicate a faulty voltage regulator or more specifically, shorted.  A shorted condition would not adjust to the need/status of the battery but supply to the battery an always maximum charging current, hence the overcharging.

On most versions, the voltage regulator would be behind the cover below the battery.

Good luck and thank you for asking FixYa.

Never saw a charging system problem cause anyone to fail inspection. But, overcharging will cook the water out of your battery and can damage the computer system if not taken care of. Overcharge can be caused by either a grounded alternator field wire or a bad regulator. Since the condition appeared after replacing the alternator it too is suspect as an internal grounding can also cause that.
