Why when I put my paslode battery on to charge does the charger lights keep flashing green red, not just stay on green or red is the battery faulty

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

Hi, you answered it your self, the battery is gone, that is what the charger is telling you, it will no longer take or hold a charge. Replace it and you will be back in business.

Replacing battery is not always necessary. Per paslode website, when the charger is flashing back and forth between red and green it is in slow charge mode. It takes 20 minutes to get out of slow charge. After 20 min the light should be solid red until full charge is achieved. If the red green flashing continues after 20 min then there may be a problem with the battery

The battery is too discharged and the only way to charge it is to give it quick with something giving out a higher voltage. The batteries are 6V so use something like a car battery charger (12V), hold the red (positive) to the battery positive (+) connection and the negative to the batteries negative (-). Hold for about 60 seconds then put the battery back into the paslode charger and it should charge correctly. This works for most similar batteries such as those for laptops or drills too. They get too discharged and the charger will not recognize them correctly.

The alternate green red flash is a deeply discharged battery and try two things before you rush off to get a new one. !. Make sure the terminals of the battery and charger are clean. I had a slight spot of corrosion on one terminal. I cleaned it with a finger nail it worked. Put it back on charge if the red green flashing lasts longer than 20 minutes. It's Amazon time!!

To prevent such problems as much as possible, you can regularly clean the charging contacts of the battery and the charger
