SOURCE: battery charger

Take your charger out on a boat and dump it into the sea. Then go to the store and buy a new one.

SOURCE: 18 volt ryobi battery charger...green & yellow lights come on wha

talked to Ryobi and they are vague. It can either mean that the battery is bad, or the charger is bad and another one that maybe the contacts of the battery are dirty or not seating fully in charger. What I would look for in this instance first unplug the charger and look into charging slot to make sure the terminals of the charger are not bent and they come out into the cavity where battery would go. If not gently pull terminal into opening and retry. Sorry I couldn't be of more assistance

SOURCE: can a bad ryobi 18 drill ruin a new 18volt ryobi battery

If the drill has a short in it, then yes, it could short the battery out. Probably in the trigger switch.

No, absolutely not! But it won't charge it either.

SOURCE: Red light in charger flash when battery is put in

This behavior is typical of trying to charge a battery that is wither too hot (let it rest for a hour) or one that has done its job and is ready for the battery retirement home. Replace your battery for best results with your Ryobi battery powered tool.

On some chargers, when the light blinks rapidly, it means that the battery is bad. Try looking up charger information on-line.

Makita battery charger wont charge


If both lights on the charger are flashing it is indicating you have a bad battery and the charger will not charge the battery. The charger has circuitry that tests the battery and if it 'thinks' the battery is defective it will not attempt to charge it. The only way to verify whether it's the battery or charger is to try charging your battery on another charger or try charging another battery on your charger. Most of the time it's a bad battery.

My charger is flashing red when i place the battery in it


Ridgid charger lights read as follows: Solid red; charger has power. Flashing red; charger is evaluating the battery, checking if it's cool enough to charge and if it is in chargeable condition. If the battery is hot, i.e. just came off the tool after extended use, it won't charge the battery until it cools down. Flashing red & green; the battery is defective and the charger will not charge it. Solid red & flashing green; battery is charging. Solid green; battery is full.

CHARGER PROBLEMS


The flashing light indicates the charger is charging the battery (or attempting it) and if it never finishes charging you should try to charge a different battery, if the charger charges that one ok then the battery is bad.

My new Black Max 24v drill charger will not charge the battery


You indicate that the drill is new. I'd suggest you return it for a replacement. Seems to be a defective or wrong charger. If you have problems and If you paid by credit card call the card company and have them stop payment on that charge.

Green and red light comes on when i put battery in charger what does that mean?


Here is the manual:
http://toolboyworld.com/eBay/Ryobi_P120/P120_566_eng.pdf

Red = quick charge
yellow = evaluating
green = charged

CHARGING A COOL BATTERY PACK
If battery pack is within normal temperature range, the red LED on charger will come on.

Red LED should remain on for approximately 1 hour then the green LED will come on. Green LED on indicates battery pack is fully charged and charger is in maintenance charge mode.

When charging battery flashes red then stays on red.how long should it take to change to green?.its a dewault9130 18 volt


it doesn't change to green, the solid red light means it is fully charged, there should be a legend on the front of the charger to help you with this. If it flashes real fast the battery is malfunctioning and slow flashing is charging and again solid is fully charger.

Batteries don't charge. I have a new battery, and neither of the old or new batteries work in the charger. I get flashing lights only, sometimes red, sometimes green, but in the end, the battery isn't...


Dust getting in the charger is a problem, Try blowing it out with a moisture-free dust remover, found at most any store. Green flashing means improper power, due to dust or power from the outlet, try a differant wall outlet. Red flashing means the charger or battery is to hot and must cool down before it will charge. The charger will not charge a battery if the lights are flashing. Solid Red light means it is charging and solid green light means it is charged. Plug the charger in first before putting the battery on the charger. If the charger has been droped or hit the floor the coil inside could have broke loose and dammaged the charger requiring it to be replaced.

Upon power up, 3 red LEDs flashing rapidly continously, no power.


The control systems on power mobility equipment have a "prevent" circuit that immobilizes the equipment while it is plugged into a charger, so folks won't take off with it plugged into the wall outlet. When you turn it on when plugged into a charger, the display will flash constantly, or sweep constantly, depending on the manufacturer. This is normal. Your off-board charger should have a red light to indicate power to the charger, and another light for the charge status. Yellowish means it is charging, when it turns green, you are fully charged. If the status light is green all the time, that is an indication that the charger is not functioning properly, or that the batteries are below a chargeable state. Check charger output, which should be 26-28 volts dc, and each battery should show at least a 12 volt reading, but around 13.5 volts with a full charge. If one or both of the batteries drops below 12 volts after a short period of time, it's time for a fresh pair. Fully charge new ones before using the chair.
