You cannot over charge a battery pack as the charger stops at full charge. However by recharging a partially used battery pack you can develop a memory in the pack that the charger will not charge past

Hi,
your NG3 should have been preprogrammed for the type of batteries you are charging. The NG3 has the 3 wires from the power cord. Here is what I have done:
Brown from charger goes to black wire
Blue goes to white wire
yellow green goes to green ground.

The battery is 14.4 volts so the charger should be 14.4 volts.

If you have tried discharging the batteries prior to charging them already with no result and from what you describe in your post, then I would have to say the charger has issues. Go to HD or Lowes (not sure if Lowes carry Makita) but another charger and test your battery again. If you get the same fault, there is an issue other than the charger, if not you need a new charger anyway. If you get the same fault with the new charger, you can always return the new one. Short of opening up the charger and using a volt meter, this is the easiest way to test to pinpoint the real problem. I hope this helps and good luck!

About the only indication if the charger is not working is when you put the batteries into the charger and no lights come on. This indicated that the charger is faulty. If the lights come on it is most likely the batteries. The best thing to do is take the batteries and charger to a Bosch service center and they will test them for you. Most will do this for free.

Can i over charge my mobility scooter go go pride


Yes you can overcharge a battery, it all depends on the charger your using. Most chargers are single stage chargers. Most scooters come with a single stage charger. My scooter has a built in single stage charger What this type of charger does is output a constant 24v @ 4amps.The problem is batteries amperage requirements decrease as the battery charges. An overcharge will occur when the battery is charged. It requires very little amperage to maintain a charge on a fully charged battery. A single stage charger like mine will output 4amps regardless of the state of charge of the battery. Batteries bring charged with single stage chargers loose their electrolyte. What happens is overcharged batteries break down the electrolyte into oxygen and hydrogen. So overcharging will cause a battery to "boil-out" its electrolyte. Batteries don't work without electrolyte. In the old days there were only single stage chargers. That was the state of the art back then. So to cope with the constant overcharging batteries had refill ports where you could replenish the electrolyte using distilled water.

Scooter batteries are far and away different from the lead acid of the 1970's. Scooter batteries are sealed, they are deep cycle, they use a glass mat soaked in gelled electrolyte. These glass mat batteries optimize the electrolyte used so they can use allot less of it. These newer batteries have a lot more power in a lot smaller package but they have a draw back, they must be charged properly. You can absolutely can not charge these batteries with a single stage charger. Actually you can charge with this device but you will loosed electrolyte each time you charge.

I use a three stage charger 24v @ 5amp. This charger s different from a single stage. Its what they term a "smart charger" it monitors the state of charge of the battery. As the battery charges it turns down the amperage. When the battery is fully charged the amperage is turned low enough were the charge is maintained. The entire charging process is designed to preserve electrolyte. In short this type charger will not overcharge the battery.

Will 18 volt black & decker charger over charge battery


Hello Howard, There are two different kind of cordless drill chargers. One is a smart charger that will not overcharge your battery. It usually has a stand alone base that the battery plugs into and sometimes may have a red and/or a green light to let you know it is charged. This charger will stop charging when the battery is fully charged after an hour or less. The other one is a dumb charger that can overcharge your battery if left on the charger too long. This charger usually has a square or rectangular transformer that plugs directly into your wall receptacle. This charger may take up to eight hours to fully charge your battery and will continue to charge until you unplug it.

Put a new alernater an still over charging


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.
  2. Faulty Alternator
  3. 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.
  4. Incorrect Charger Use
  5. 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.
  6. Faulty Battery Chargers
  7. 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.
  8. Heat
  9. 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.

The battery has been overcharged and is going to burst if you continue to charge it, Replace the battery again and the charger as well or only charge the new battery when it is low on charge

There are too many unknown variables in this. One is the charger that you are using. Two is the amount of charge in the battery when you charge it. These are things you must know. However with new chargers you can be sure they wont over charge the battery. If you are still worried about it, put it on charge and check it every hour or so and don't go past 8 hours.

if the charger is rated at 10 amps or more yes,it received a 'quick charge' enough to render it serviceable.the charger should be 'overcharge protected' so you could give the battery another 'zap' just prior to installation.

How do I charge My Pronto M51 motorized wheelchair?


Margie,   Yes you may charge it overnight. If you use it everyday,charge it every night. Once the charger senses 24 volts it stops sending a charge,so they cannot be overcharged.  I suggest when you go to bed put on the charger and unplug it when you get up in the morning.

I need to know what battery in float mode means on my battery charger. It doesnt say and its a smart charger 2amp 6amp and 12amp charger.


Float mode on a battery charger generally means that battery has been fully charged at a faster rate, and the charger is now maintaining the full charge, without overcharging the battery. You can usually leave the battery connected to the charger indefinitely - float mode will ensure it is always at it's peak charge.

Please rate if this helps :)
