SOURCE: It tells you to that you should charge the battery

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.

Ryobi 40v trimmer stops working with 1/2 charge left on battery


Battery is weak. Those lights are really useless...more a marketing gimmick. It almost sounds like it developed a memory...this happens when certain types of batteries are not fully discharged before being placed on the charger. Replace the battery and make sure to follow charging directions for that particular type of battery

I have the cobra CXT275 they have been on the desktop charger for 5 days. They won't charge over a 1/4 of the way how do I get the maximum charge?


Just went to their site and this is what it said:

This may simply be a matter of misinterpreting the low-battery indicator. We use two different types of battery indicators:
  1. Battery Level Indicator: This battery indicator is always visible, and has several segments. When all the segments are lit, the batteries are full. When only the last segment is lit, the batteries are almost exhausted.
  2. Low Battery Indicator: This type is usually NOT visible. It only appears when the batteries are low, at which time it flashes on the display to warn you of a low battery condition.
Please note that when you turn on your radio it first performs a display test. Everything on the display will light up for a few seconds, including the Low Battery Indicator. This does not mean that the batteries are low. After a few seconds the display test will end, at which time the Low Battery Indicator should go away.

Headset not charging


Sometimes it takes longer than two hours. Leave it plugged in overnight if you can. The indicator light should go off after fully charging.

Need to know what the lights mean on a makita dc24sa charger


• When the battery cartridge is inserted, the charging light color will change from green to red and charging will begin.
The charging light will remain lit steadily during charging.
• One red charging light indicates charged condition in 0 – 80% and two red ones indicates 80 – 100%.
• With finish of charge, the charging lights will change from two red ones to two green ones.
• The charging time is as follows:
Battery B9017A, BH1220, BH1420, BH9020A: approx. 20 minutes.
Battery B2417, BH1233, BH1433, BH2420, BH9033A: approx. 30 minutes.

There are 4 reasons why your unit is behaving this way:
1. Charger is the problem.
2. The docking station is the broken.
3. The battery is broken or not accepting charge.
4. The actual unit is the problem.
It is very hard to tell which one is causing this to happen.
Let us do some troubleshooting first:
1. Plug your charger in an A/C outlet and make sure the red power light (left) is lit, otherwise the charger or the docking station is broken.
2. You can test the charger with a multimeter. Unplug the charger from the docking station and measure the voltage across the outside and inside, it should register more than 5 volts DC. If there is a 5Volt DC the docking station is the problem otherwise the charger is broken.
3. If the red power light is lit and the status light (right) is lit too, your docking station is broken.
4. If the red power light is lit, dock the unit into the charger, the status light (left) should turn red when your battery is accepting charge or turn blue when your battery is fully charged.
5. If the status light will not lit at all (while the red power light is on), tap the screen while the unit is docked on the charger. If the unit will become alive, you need a new battery otherwise you need a new unit.

12 hours is very long time to charge, the status light should turn to blue in less than 2 hours especially for a new battery.
