Have 24v sds drill older type the one with the charging lights on 2 of the batteries will no longer charge just go to red on charger unit can they fixed

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.)

I DON'T KNOW. COULD BE UNDER WARRANTY FOR FREE REPAIR OR REPLACEMENT. I HAVE RYOBI AND UPDATED ITEMS. THEY HAVE 3 CHARGERS 2 SMALLER RATED CHARGERS WOULD NOT GIVE ME
'FULL CHARGED' LIGHT. OLD BATTERIES WOULD NOT CHARGE ON OLDER CHARGER. FROM INTERNET ADVICE, I REPEATEDLY PLUG AND UNPLUG CHARGER BY HAVING PLUG LOOSE WHEN DOING THIS. SOMETIMES IT TAKES 4 TIMES TO CHANGE FROM DEFECTIVE TO CHARGE. SOMETIMES IT TAKES 20 TIMES TO SEE THE CHARGE LIGHT.

Have you tried charging and discharging the battery a few times, sometimes that helps build up the charge.

Batteries plus, heres their number,,,, Call a friendly Battery Expert at 1.800.677.8278

If both lights are blinking on the charger after putting the battery on to charge, the battery is no longer chargeable. Most likely it's bad cells inside the battery, the charger is reading the battery as bad and will not charge it. The only fix is to buy a new battery.

Black Max 24v power drill

Allied International sells them at 1-800-248-6657, drill part # JDB240R. Have the part number from your drill available (on the label on side or top of drill...a number like 33643)

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.

Write a registered letter to the black Max official headquarter stating that you did make your charger replace cpl times and asking for full refund otherwise you'd get into court procedures... Easy and effective way to have result.

check the conecking prongs on the battery and the charger. also check the charger, make sure its charging if not check the fuss in the charger. some battery of that type wear out and wont take a charge my need a new battery

If it is out of warranty open it up and check the fuse inside. This has happened to me several times with several brands, and it has always been the fuse. They are usually replaceable at Radio Shack or the Auto Parts Store.

Hope this helps!
