Battery will not charge.

No continuity between the positive D C connection at the plug in point and the positive connection at the battery. As though the connection is broke.

    I figured it out. Took the battery out and made jumpers with paper clips and charged the battery out side the note book. After one hour installed the battery, it had 91% charge, plugged it in and it went on up to 96%, seems okay now. I did not use it for several weeks so the charge got too low.

Your not going to get continuity when you measure through a battery charging circuit. Check the power supply.

Charging system diagrams for 2002 dodge dakota


There is 4 gauge black/red wire going from te alternator to Fuse #2 in the PDC. The alternator and battery both connect (positive side) at this point. The alternator's path to charge the battery is from the alternator, to this tie point, then to the battery. In the wire, between the alternator and the PDC tie point, is a fusible link. This link may have broken or melted. That would keep the alternator from being able to charge the battery. I would check this wire for continuity and replace the link if necessary.

How to Charge a Car Battery Using a Battery Charger


If you find yourself with a dead battery in your car and have access to a battery charger you are only some time away from being on the road again. Whether you are using a small car charger known as a trickle charger or a larger unit on wheels, you can charge your battery effectively. There are safety concerns though. Be sure to check the warnings
1、Locate the battery or remote charging point by consulting the owner’s manual. You can also open the hood to find the battery. The laptop battery may be under a seat, in which case a charging point may be provided under the hood.
2、Remove any plastic covers that may be protecting the positive and negative posts of the battery. Just push the covers to the side as they are usually pliable. Note the location of positive and negative terminals signified by a plus and a minus sign respectively.
3、Locate the laptop car charger so that its cables will reach the battery. Make sure your charger will reach an electrical outlet. Add an extension cord if needed.
4、Place the clamps of the charger on the battery making sure that the red handled clamp goes to the positive battery post and the black handled clamp goes to the negative laptop batteries post. If you are not sure, trace the cable attached to the clamp back to the charger and look for a positive or negative designation. If you are still not sure, stop and seek professional advice.
5、Plug the charger in, making sure that the selection switch is set to off.
6、Select the appropriate voltage and or rate (almost all cars have a 12 volt system). If time permits choose the slower rate and plan on charging the battery for two hours. This selection will turn the charger on. If the charger has a timer, set it.
7、After charging the battery, unplug the charger, disconnect the charger’s cables and start the car.

Sony FD mavica will not run on charged battery, will run plugged in to charger


You either have:
1) a false positive on your battery, meaning that they aren't really charged even though they say they are (especially common the older a battery gets), or
2) the battery connection is faulty/dirty, while the AC adapter is fine. If the AC adapter uses the battery port, then the battery is your problem.

Yes it is, seems there is some problem with the power state detection and changing of the load mode. Might by a physical problem, so I am not sure you can fix it.
At least check your power plan details and see if there is any error with the ACPI devices in the device manager.
In general, if you use the laptop when plugged, you should take out the battery to maximize the battery life (prevents useless load cycles).
Also configure Windows to optimize battery usage.

I have a Panasonic KX-TG6051CM


I had the same problem, and it seems that the battery charging circuit in the handset had locked up, constantly charging the battery until it overheated. I was able to reset the circuit in my handset by completely draining the battery. Here is the procedure:

1. Remove the handset from the charging cradle, and leave it on for a few days until the battery runs out, and the handset finally turns off. At his point, the battery will be very low, BUT NOT COMPLETELY DRAINED.

2. Next, you must manually drain the charge remaining in the battery by shorting out the two contacts on it. Shorting won't damage the battery, since it is holding very little charge at this point. An easy way to physically do this is to remove the battery, and place a piece of thin wire across the the two contacts of the HANDSET. I am referring to the contacts inside the handset that connect to the battery, NOT the contacts on the bottom outside that connect the handset to the charging cradle. Next, put the battery back in, sandwiching the wire between the battery's contacts and those inside the handset. This will hold the wire in place. DO NOT PUT THE HANDSET BACK INTO THE CHARGER, WITH THE BATTERY SHORTED OUT.

3. Wait about 30 minutes for the battery to completely die. Remove the jumper wire, and but the handset back into the charger.

4. If the battery was fully discharged , you will get a message on the handset telling you that you should let it will charge for 7 hours. If you do not get this message, then either the battery was not fully discharged, or your problem is different from mine. Try the procedure again in Step 3 for another 30 minutes to discharge the battery some more.

5. If you get the "Wait for 7 hours to charge" message on the handset, then leave it in the charging cradle for the 7 hours requested. After that, it should work fine.

Let me know how you make out.

SPS1 charging system


Borrow a multimeter and check the voltage (and current if you can) going to the battery while the unit is turned off. It should still be charging the battery if it's still plugged into the wall socket. If it is not getting about 13 volts, it's not going to charge the battery. If that's the case, then there's something wrong with the transformer, or another part of the charging circuit. The downside is you can't use the unit without the battery being connected. If the unit still works and sounds good even though it's not charging the battery, then just put the battery on a separate charger every week or so.(I use the SPS1 for my computer and love it!) Good luck with it. H.
