My battery will not charge in charger

It sounds like there may be an issue with the charging circuitry on your Makita DC18RC charger. Unfortunately, without a schematic, it can be difficult to diagnose the problem. However, here are a few things you could try: Clean the battery contacts: Sometimes, a buildup of dirt or debris on the battery contacts can prevent the charger from properly detecting the battery. Try cleaning the contacts on both the battery and the charger with a clean, dry cloth. Check the power source: Make sure the charger is plugged into a working outlet and that there are no issues with the power source. Check the thermal sensor: The Makita DC18RC charger is equipped with a thermal sensor that prevents the battery from charging if it gets too hot. If the battery is too hot, let it cool down before trying to charge it again. Try a different charging mode: The Makita DC18RC charger has two charging modes - rapid and maintenance. Try switching to the other mode and see if that makes a difference. Check for loose connections: Inspect the charger and battery for any loose connections or damaged wires. If you find any, try repairing or replacing them. If none of these steps resolve the issue, you may need to take the charger to a professional repair shop or contact Makita customer service for further assistance.

Check your charger and battery contacts. Cleaning battery contacts on the radio and charger with a pencil eraser will remove dust, dirt, debris, and hand oil which may cause the battery to charge poorly. Secondly, you might want to check that your charger itself is working properly. If you have a second known good radio you might try charging it on the same charger.

Best regards.

It could be the battery, the charger, dirty contacts either on the battery, the charger, or the camera. And, of course, there's the possibility that the camera itself is bad.

If you have a voltmeter, try measuring the voltage between the battery terminals. Clean the contacts on the battery, charger, and camera with a clean damp cloth. Try charging the battery again.

Bruce, you didn't provide a lot of information but I can tell you that the few times this has ever happened on my Nikon D-90, the battery did not charge, would not charge and I had to throw it away, or it was a charger problem.

I've had it happen when I tried to charge it on my corded Nikon Charger and I never got a charging complete indication after charging over night. When I put it in the camera, the camera indicated it was not charged even though the charger indicated it was charging. But, when I put it on a travel charger, it charged in about an hour and worked fine. The next time I put it on the Nikon charger, it worked fine.

I suggest you verify that the battery is good and charged or capable of charging. If it is, then check to make sure the battery contacts are clean both on the battery and in the camera.

If the contacts are clean and you're sure the battery is good and charged, I'd say the next step is to contact Canon. I've heard their customer service is very good.

The battery is gone for sure... You must get new one... take a look on amazon (my recommendation): Amazon com nailers paslode battery

Rechargeable batteries don't last forever. This one may have simply stopped working.

However, it is worthwhile checking that the contacts on both battery and charger are clean. Dirt or corrosion can prevent the battery from charging.

There is also the possibility that the charger has failed. You can buy a new battery and try charging it. If it charges, then the charger is good and the old battery was the problem. If it doesn't, then you must get a replacement charger, and you will have a spare battery, which is no bad thing.

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.

Clean contact points of both battery and charger with q-tips dipped in rubbing alcohol. This solved my problem with blinking lights and not charging of the batteries.

I had this problem a few weeks ago (i.e. flashing red LED). All I did was remove the power plug from the charging unit, turned it around 180 degrees, then plugged it back into the charging unit. Red LED came on steady & the battery (which is the one that came with the camera) recharged as normal.
