What is the residual voltage on your battery, if it is too low, charger will not engage. If the voltage is below the threshold allowed, simply jolt the Nickel Cadmium battery with a car charger to bring it up, then install on charger.

SOURCE: It tells you to that you should charge the battery

The problem is your batteries are either over heating or worn out. You might also have a problem with the charger but you'll need Dewalt tech support to determine if it's good or bad.
The first thing to do is clean the contacts. Use a white plastic pencil eraser and clean all the contacts you can reach. If there are any contact you can reach with the eraser use a Q-tip that is just damp (not wet) with rubbing alcohol to clean them.
Discharge your batteries completely then put them in the freezer for 8-24 hours. Take the batteries out of the freezer and let the set 24-48 hours after that put them on the charger, they'll either charge or you need new batteries (more likely) or a charger.

SOURCE: my charger displayed cold/hot pack

This is indicating the battery is too hot to charge, usually after coming off the tool right after some hard work. During the charging process the battey heats up so if you charge a hot battery, thereby making it hotter, you shorten the lifespan of the battery considerably. If you are getting a hot/cold pack delay indication on the charger, it should automatically start charging once the battery has cooled down sufficently.

CHARGING THE BATTERY PACK
Battery packs for this tool are shipped in a low charge condition
to prevent possible problems. Therefore, you should
charge them until the green LED on the front of the charger
comes on.
NOTE: Batteries will not reach full charge the first time they
are charged. Allow several cycles (operation followed by
recharging) for them to become fully charged.
CHARGING A COOL BATTERY PACK
See Figure 3.
If battery pack is within normal temperature range, the red
LED on charger will come on.
NOTE: If the charger does not charge the battery pack
under normal circumstances, return both the battery pack and
charger to your nearest Ryobi Authorized Service Center for
electrical check.
n Charge the battery pack only with the charger provided.
n Make sure the power supply is normal household
voltage, 120 volts, 60 Hz, AC only.
n Connect the charger to the power supply.
n Place the battery pack in the charger aligning raised rib
on the battery pack with the groove in the charger.
n Press down on the battery pack to be sure contacts on
the battery pack engage properly with contacts in the
charger.
n Normally the red LED on charger will come on. This
indicates the charger is in fast charging mode.
n 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.
NOTE: The green LED will remain on until the
battery pack is removed from the charger or charger is
disconnected from the power supply.
n If both yellow and green LEDs come on, this indicates
a deeply discharged or defective battery pack.
Allow the battery pack to remain in the charger for 15
to 30 minutes. When the battery pack reaches normal
voltage range, the red LED should come on. If the
red LED does not come on after 30 minutes, this may
indicate a defective battery pack and should be
replaced.
n After normal usage, a minimum of 1 hour of charging time
is required to fully recharge battery pack.
n The battery pack will become slightly warm to the
touch while charging. This is normal and does not
indicate a problem.
n Do not place the charger and battery pack in an area of
extreme heat or cold. They will work best at normal room
temperature.
NOTE: The charger and battery pack should be placed
in a location where the temperature is more than 50°F
but less than 100°F.
n When batteries become fully charged, unplug the
charger from power supply and remove the battery
pack.

Ryobi charger model # 140295003 has a red and yellow light. When charging red light is on what does the yellow light mean? Also how long should the battery be left in the charger?


Completely wrong. Quoting from the user's manual:

"The charge indicator light (LED), located on the charg- ing stand, will light up red and glow when the char- ger is properly connected to power supply. This light indicates the charger is operating properly. It will remain on until battery pack is removed from charging stand or charger is disconnected from power supply.

After normal usage, 3 hours or less of charging time is required to fully recharge battery pack.

If both red and orange LED indicators glow, the battery pack is deeply or completely discharged, and 6 hours or longer of charging time is required to fully recharge battery pack.

Note: If charger does not charge battery pack or orange LED continues to glow after more than 30 minutes of charging, return battery pack and charging assembly to your nearest Ryobi Authorized Service Center for electrical check."

So to summarize: red = charging. orange (yellow) = fully discharged battery. orange after 30 minutes - bad battery or bad charger.

HELLO: OUR MILWAUKEE 48-59-2401 BATTERY CHARGER IS NOT CHARGING OUR 48-11-2401 BATTERY PACKS. WHEN YOU RUN THE PACK DOWN TO 1 OR 2 LIGHTS & PUT IT IN THE CHARGER BOTH RED & GREEN LIGHTS FLASH....


If both lights are flashing after you put a cool battery on the charger, the battery is bad. It could have a bad, worn or shorted cell or other problems inside and the charge will not charge it as long as it reads it as a bad battery. Rechargable batteries do have a finite life determined mainly by how many times you recharge them.

I can't find the charging manual and I am intuiting from the drawings that if it has a steady flashing red it means it's charging, but I would like to read the instructions.


Operator's manual for DW926K-2 is here. It doesn't specifically address solid red light, but that's what mine does when I first put it on, so solid red indicates that it is charging.

If it is flashing the red light with two fast blinks followed by a
pause. This means the power source has out of spec for the charger (such as a generator not producing electricity at 60Hz).

If the red light flashes long, then short, you're in Hot/Cold Pack Delay mode which means it won't charge the battery until its temperature has stabilized.

I hope this helps! If so, please vote. Thanks.

Green & Yellow light on 14.4V charger


It sounds like your battery is bad.

If both yellow and green LEDs come on, this indicates
a deeply discharged or defective battery pack.
Allow the battery pack to remain in the charger for 15
to 30 minutes. When the battery pack reaches normal
voltage range, the red LED should come on. If the
red LED does not come on after 30 minutes, this may
indicate a defective battery pack and should be
replaced.
n After normal usage, a minimum of 1 hour of charging time
is required to fully recharge battery pack.

Dewalt battery charger won't charge


As you know, solid red on your charger means that the battery is fully charged and the BLINKING red light means the battery is charging. Unless the light is blinking irradically everything is working the way it is supposed to. If the light is blinking irradically, the battery may just be too hot or too cold to charge ( like when you are driving many lags and your battery dies) and in this case simply wait 15 minutes to charge. If you get a fast blinking light still, the problem probably is with the battery.
