My charger cord seems to have a short and it's not charging the battery or connecting so it runs on the battery till the alarm sounds then it shuts down Could it just be a bad cord?

If your Pramac 12k battery charger is displaying a failure alarm, there could be a few possible causes:

1. Check the voltage level of the battery: Make sure that the battery is at the correct voltage level and that it is properly connected to the charger.
2. Check the charger connections: Make sure that the charger is properly connected to the power source and that the connections are not loose or damaged.
3. Check the charger's fuse: Make sure that the charger's fuse is not blown.
4. Check the charger's cooling system: Make sure that the charger's cooling system is working properly and that it is not blocked or damaged.
5. Check the charger's electronic board: Make sure that the charger's electronic board is not damaged or malfunctioning.

Do you also have a good battery that runs the drill well to proof the drill is good, and a volt meter (multi meter)?
I have several cordless tool batteries that show the rated voltage on a meter, and register as fully charged when on the charger, that no longer have any current capacity. They will barely turn the drill and die in seconds. This is a different problem than when freshly charged run fine but lose their charge in a few days or so. That is caused by internal short circuits in some or all the cells from "dendrites", a build-up of small amounts of the cell plates as little branches growing on the plates until they reach the other plate, causing a tiny short circuit. Dendrites can sometimes can be burned off, the way I do it can be extremely dangerous and I do not recommend it. I do it by putting 4 battery chargers in series, giving me an open circuit voltage of 59 volts. I for a no more than 4 seconds connect them to the battery - to - and + to +, with a current in excess of 50 amps. The battery gets hot and could explode, so I do it by reaching around a 1/2" thick poly-carbonate shield. Lacking a shield, i use a power strip to plug the chargers in Have the power strip unplugged from the outlet or extension cord, connect the charger clips to the battery, and from a distance, plug in the power strip just for 2-3 seconds. The battery may be quite hot. I then check the battery voltage, it is usually a bit higher than the voltage rating. I put the battery in the drill and if it makes a few turns, i run it till the drill stops, then charge the battery normally. I use 2 small 12 v chargers that have a 50 amp jump-start setting and two that have a 10 amp rating.
The proper repair is to replace or rebuild them.

3rd party battery?

Dear Mary. All car alarm systems drain the battery after one week of the car not being used. Also, car batteries are not always fully charged on short trips because to start the engine on each short trip it drains a tremendous amount of power and a short trips do not recharge it fully. Have the car battery checked because the alarm is always on and on standby once installed, they usually have a small back-up battery in the alarm in case of car wires to the alarm have been cut, but that battery is always kept charged by the car battery, so, that is only causing a fraction of car battery discharge. However, to stop it from draining the battery you have to disconnect the alarm, and that is not a good idea. No car alarm that I have known have caused any car battery discharge, but of course if the car is not being used, or it is driven for short periods you are likely to experience a drained battery. Some batteries last more than 5 years not stop while cheaper ones have a lesser life expectancy, but again that depends on a lot of factors, heat from the engine, not enough charge because the alternator has a burnt diode, interior lights left on, too much cranking of the engine to start it and not enough miles done to recharge the battery. Try to get the battery checked and if you do not do any driving for a week, there are a number of solar powered battery charging panels that trickle charge it on sunny days but in winter I suggest you buy a charger that you can connect to the battery to keep it charged. Once charged the charger automatically cuts off and stays on stand-by until the car alarm has discharged it a bit, then the charger sensed the voltage drop and recharges it again, repeating the cycles until you need the car to go out. These small car battery maintenance chargers are inconvenient if you're not using the car too often. Some car alarm with go off when the car battery is disconnected. It's part of the protection the alarm offer. They may not be disconnected from the car battery unless you have a key that shuts off the alarm. But remember, the key shuts off the alarm but it doesn't mean it has disconnected the power from the battery. Check the pilot light status. If it flashes after the alarm key has been turned to off, it means the power is always there. Other alarms remain silent when the car battery has been disconnected from the clamps. If you garage the car at night, you can have a switch installed in the car that switches on the power to the car alarm or you can have the switch connected to a special relay activated Kill Switch that disconnects the battery altogether, but if your car alarm starts to squeal, then you don't need this switch. so try it first, disconnect the car battery and see if the alarm goes off. If not, then the Kill Switch is an option. If it goes off, then there is nothing you can do but to try and have the car battery checked and if you're not driving much or drive short trips, either a solar charger or a Mains powered auto charger can be used to keep the battery trickle charged. But before I go, you say you got an after market car alarm. Looks like it has been wrongly wired, who know. Have it checked by whoever installed it. Good luck.

I had same problem. I found a Zip Tie had dug in the wires that only effected the charging not the controlling part. Till the Zip Tie dug in farther, till it cut another wire, preventing the chair to move. That's is when I discovered it. After finding this out, my old batteries were probably good. I just assumed it was their end of life

sound like you need to replace the power pack.

Make sure that the charger is fully connected to the scooter; ususally the controller lights will go slowly left to right to indicate it is charging. Make sure the charger is plugged directly into the grounded wall outlet, not into an extension cord or power bar. If the charger is not being recognized by the scooter, you may need to replace the charger, or at least the power cord to the charger.
If your scooter has been sitting unused for a while? If so, the batteries might not charge anymore and will need to be replaced. Contact the manufacturer for a service call or troubleshooting over the phone.
Good luck!

I got a brand new 170 battery for my studio 1737 . Now the battery has charged, but I plug it in and the window says battery plugged in, but not charging

First thing check that the battery charge light is on when the battery and the charger are connected.
If it is it indicates that the power supply is charging the battery,
If it isnt it may indicate a fault with the battery or that the charger is not compatable with the laptop or that there is a fault with the charger.
If the battery is charging then try running the laptop on battery only without the charger and on charger only without the battery.
This will eliminate which one is faulty.

You mentioned that if you wiggle the cord then the light comes on again.
Check to see if the charger end plug is lose or the actual port on the laptop is lose.
If the charger plug is lose then return to seller and make sure they gave you the correct charger. if the actual port on laptop is lose then perhaps u got a bad connection and you need electrician or local laptop technician to open it up and solder properly on motherboard.

Let me know how it goes.

IT sounds like your laptop or powersupply/charger is at fault. Try to use a different charger, and if possible use your battery in a different computer. That way you can narrow down where the problem is. It might ba a faulty connection where the charger is connected to your computer. To check this out, try running the computer on AC without the battery installed. If it suddenly shuts off it's a problem with your powersupply or possibly the connection plug in the cimputer.
