My Dewalt battery charger DE9116-XE flash's fast after slowly flashing at the start. The explanation on the charger is if this happens to replace pack, but this is a new battery I just bought It.

some batteries are bad from factory, you should exchange it for another and try again. Make sure the battery voltage and type (ie. lithium, Nickel Cadmium,etc.) match the charger. If not, you can buy most replacement batteries for older models on the internet. If a second battery doesn't work - it's the charger .

If this is a newer purchase, my newer Milwaukee flashes slow for the first two beats and then quickly while it reads the battery type and then shifts to the slow flashing charge light after it determines the type. this is because it is a smart-charger and can charge different types of batteries

Red light flashing on charger

A red light indicates the charger is charging the battery, an amber light means it has switched from fast rate charging to trickle to keep the battery topped off, and green would mean the battery is completely charged. But don't be fooled waiting for green, many times the charger will only be on green for a moment before changing to amber and keeping the battery topped off.

Flashing can be a sign of a problem on some chargers.

A rapid flashing red can on some chargers indicate a bad or shorted battery, or a bad battery contact in the charger itself. If in question, try a different battery on the charger or compare with another charger to determine if the blinking is normal.

Best regards.

I have a dewalt de9116 charger and when a battery is put in it flashes constantly even a new battery. Is the charger defunct?

I would say tee charger is no good. The only internal component is a circuit board so it is not worth trying to repair it/get spares as it will cost the same as replacing the charger.

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.

Problem charging

If you are referring to a flashing yellow light on the charging base, this is an error code. Either the 1) battery is bad, 2) not making good contact in the charger, or 3) very very low on charge. The solution for this set of problems is as follows: 1) have the company you purchased them from replace them, 2) clean your contacts with a pencil eraser, 3) leave the battery on the charger with the yellow light flashing for an hour or two. If the battery is just very low on a charge, it will come back to life and the light will change to be constant. If the battery is bad or shorted out, the light will continue to flash and you will need to get with the vendor you purchased the batteries from.

Other things which come to mind are compatibility issues such as you are using a different battery chemistry than you had before. NiCd batteries can charge on either of the two chargers available for the P110 (slow rate or fast rate). However, NiMH and Li-Ion batteries require a fast rate charger.

If you are referring to a yellow blinking light on the radio while it is in the charger. You need to shut your radio off. Radios should always be turned off when charging. If the radio is left on you will never have a full charge. Also, if you inadvertently press the PTT while the radio is turned on, while on a charger, you can cause damage to the radio.

FYI: There is no light to show "out of range" on the radio, unless you are possibly using a trunking or repeater system. A blinking light on your radio indicates the radio is turned on and/or there is traffic on your frequency. Your charger base light can be red, yellow or green. This indicates the charge cycle status. Flashing most always means some type of error.

Best regards

Flashing lights

I had the same problem. 1 of four way's can fix it. #1 Put a batt. that has a little charge in that flashing spot 1st. and see if that works. #2 put the batt. in that flashing slot first and then in the 1st slot, If that did'nt work, #3 Put Batt. in backwards for 1 sec. in and out fast. and I do say very fast, In that flashing spot. #4 buy a new one. The one that fixed mine was #1 and it stoppppped flashing, The order I put them in was - 3-1-2-4 I put in #3 batt. first, it was the one flashing And it worked, You may have a bad batt. or it's on it's way out, but try It. worked for me!
