Charging Will no longer charge. It's not the charger because more than one charger has been tried. The battery is virtually new

My Ryobi 18V One+ charger blinks green while it's charging. When the battery is fully charged, the LED goes to a solid green. However, one battery recently had a faulty cell. After several hours on the charger, the green and red LEDs both were blinking. That indicated that the battery failed late in the charging sequence. It didn't fail the initial testing by the charger. The other battery I charged that day charged fine.

The extended capacity batteries can take 12 hours to charge in my experience. The regular batteries take less time. The charge time will depend on the battery chemistry(The older NiCd batteries take longer to charge then the Lithium batteries.)

I hope this helps. Assuming you aren't dealing with a cold or hot battery or charging environment, if you have any suspicion about a faulty battery, replace it.

(Note: I have a 12V drill as well. Those batteries takes longer to charge for the same relative capacity than the 18V NiCd batteries.)

1 Battery no longer holds a charge
2 Charger is faulty
33 Charger circuit does not function

This is assuming the mains socket works ok

Try a different charger, if that does not do the trick you know it is either batteries or charging circuit. Then change batteries, if that does not work you know it is a charging circuit fault

the charging circuit does not charge or the batteries need replacement ....IT is probably the batter. Try new batteries, if they work the problem lies elsewhere
Also, try a different charger, and the tablets charger on something else...if the tablet's carger charges other batteries that can be discounted as the problem.

SAMSUNG GALAXY S5 - NO POWER, BATTERY, CHARGING AND CHARGER ISSUES

No power, battery, charging and charger issues

This guide contains troubleshooting steps and advice to help resolve issues you may experience when attempting to charge the handset.
After performing each step, please test to see if the issue is resolved.
Symptoms:

• Battery not charging
• Battery is not lasting long
• Phone won't charge
• Charging error
• Failure to charge
• Display remains black or blank
• No power
• Boot failure
• Overheating

Troubleshooting Questions

• Are you using the correct equipment?Make sure you are using an approved Samsung wall charger and USB charging cable. Other brands of charging accessories may have different voltage parameters and could cause charging issues when used with Samsung devices.
• Have you charged your phone for longer than 30min? Leave your phone plugged in to the charger for about 30min without powering on. In some cases, it may take slightly longer for your phone to charge.
  
• Is the battery icon displayed on the screen when charging? After charging your phone for a little while you should get a battery charging icon appear on the screen which will indicate that your battery is charging properly.
  If the charging icon appears, leave your phone for a little longer before you try to switch your phone on.
  If however, the screen is blank and nothing is displayed, follow the below troubleshooting steps.
  
• Is the charging cable plugged into a USB port? Some charging cables can disconnect from the wall outlet adapter and plug directly into a USB port. However, when plugged into a USB port, the charging process is much slower due to the limited power output of USB ports. Instead, plug the device directly into a wall outlet to speed up the charging process.
  
• Is the outlet faulty? Try a different outlet or check for a switch connected to the outlet. If possible, try powering a different device on the same outlet.
  
• Does another USB cable, or wall charger work? Charging issues can occur if either the battery or charging cable is damaged. Verify that the charging contacts are clean. If necessary, clean the contacts using a cotton swab and rubbing on isopropyl alcohol.
  If possible, test the charging cable by plugging it into another device and seeing if the device charges. Alternatively, try charging the device with a different cable. This may mean changing out the cable or the adapter on two-piece chargers.
  If charging through a car charging kit, ensure that the car engine is running, and if possible try to charge other devices using other cables, through the same car kit. If none will charge, then it is likely there is a fault with the car charging kit. It is recommended to continue to cross-test devices, cables, and car kits until the problem device can be identified.
  If the device charges when using a different USB cable or wall charger, the issue most likely lies with the charging accessory. In this case, follow the approved charger repair / replacement process.
  Also, if the charger is connected via an extension or other multi-socket adapter, remove this and plug the charger directly into the wall-mounted socket. This will eliminate the possibility of a fault with the adapter.
  If you are still unable to charge your device, continue to the next step.
  
• Has the phone experienced any shock or exposure to water? Accidental physical shock to a handset can sometimes cause problems to arise with battery or charger, as these components contain delicate parts, particularly. Damage can occur either to the component itself, or to the component's connection to the motherboard.
  Water exposure can also lead to damage of these components, however due to the slow way in which this type of damage can manifest itself, the cause may not always be readily obvious.
  With any physical damage of this nature, the only recourse is to contact the device manufacturer, and follow their approved repair or replacement process.

u r charging,but the charging stays for a few minutes,go for a new battery and try

NiMH is a universal replacement battery. It will work in place of nicad and other types of rechargeable batteries, and will work with virtually any charger

The rapid rate charger WPLN41__ will typically charge a battery in 90-120 minutes. Your battery should be depleted or nearly depleted when you place it in the charging stand. Be certain your radio is always turned off, when charging an attached battery. The NiMH battery will generally go 12-16 hours on a charge when new. If you work an eight hour shift, you might see if the radio will go 2 days on a charge. Later as the battery ages, you will need to charge it nightly. (Think of putting it in the charger as putting it to bed at night.)

Rapid charging is necessary on NiMH and Li-Ion batteries. They require a "hotter" charger, a fast rate, to completely charge the battery. It will not harm this chemistry of battery. It is safe to leave the battery on the charger overnight, or for a weekend. We would not recommend leaving the battery on the charger longer periods of time, as that will age the battery and reduce its life.

(Sidenote: Frequent rapid charging will however reduce the life of a NiCD battery.)

If very well could be the charging port. Have you tried a different charger?

If it is the charger port, You have 3 options.

1. get it repaired, warrant if possible
2. Get a new one
3.Get an external battery charger and charge battery separate from phone.Another battery and charger will set you back about 10 dollars on ebay.

For more information and links to the parts check the following link below.

Samsung SGH-D900 charging problem repair

You have defective batteries. Either they are old and used and can no longer take a charge and should be replaced, or they have a problem not allowing them to be charged.

If batteries are new, seek replacements. If old, time to buy new batteries.

If this happens with several batteries, and even new ones, your charger my be faulty.
