Will dc24sa charg a 14.4 battery

Yes, the DC24SA will charge any Makita battery between 7.2 and 24 volts that will properly fit the battery slot.

It should tell you on the bottom on the charger what that means. But this means the battery is not taking its charge. Sorry bad battery.

The DC24SA will charge 9.6V to 24V Ni-MH slide style batteries (1.7Ah to 3.3Ah)

Sounds like the battery is no longer good

your fuse went bad replace fuse.

most likely your inverter is going bad,,,time for a new charger

look for your local interstate battery dealer thy rebuild them in some areas-price depends on the dealer but is cheaper than buying a new one(should be)

Your charger is malfunctioning. Return it to the point of sale and request warrenty.

try cleaning contacts on the battery and the charger then push batter in to charge, if the battey is old that will cause it not to charge. How old is the battery?
