Make sure battery is not too cold, nor too hot after prolonged usage. See if warranty is still good---probably need to replace it.

Greetings Gurus. I have Makita charger model DC18RC, battery model is 18v BL1815...manual is of limited help. I'm trying to understand what the indicator lights mean, what the time is for charging,

I agree that the pictographs are not very helpful. You probably have one of the new chargers. I have an old one, which is a little easier to figure out.

From top to bottom

1. The flashing green light with the electric plug indicates that the unit is plugged in and ready to go.
2. The flashing red little fan means that the battery is too warm so it is just cooling it and not charging it at that moment.
3. The solid red empty battery outline means that it is charging but hasn't got very far, less than 80% full.
4. The mostly full battery outline with both solid red and green lights at the same time means it is 80% full or more
5. The full battery outline and solid green with the musical notes means it is full up.
6. The broken battery outline with flashing red and green means you've got a broken battery.
7. The yellow light with the wrench means the charger is "conditioning" the battery, whatever that means.
8. The yellow light with the fan means "cooling abnormality."

Hope this helps

Red light flashing on charger

A red light indicates the charger is charging the battery, an amber light means it has switched from fast rate charging to trickle to keep the battery topped off, and green would mean the battery is completely charged. But don't be fooled waiting for green, many times the charger will only be on green for a moment before changing to amber and keeping the battery topped off.

Flashing can be a sign of a problem on some chargers.

A rapid flashing red can on some chargers indicate a bad or shorted battery, or a bad battery contact in the charger itself. If in question, try a different battery on the charger or compare with another charger to determine if the blinking is normal.

Best regards.

My glowbouy flashes green and red...what does this mean

According to the owners manual for these swimming pool lights, this is what each colored indicator means. Hope this helps.


Solid green
The battery pack is fully charged.
Slow flashing green
The battery pack is almost fully charged.
Slow flashing yellow
The battery pack is half charged.
Medium flashing yellow
The battery pack is less than half charged.
Fast flashing yellow
The battery pack has almost no charge.
Fast flashing red
A charging error has occurred and the light should be unplugged and then plugged back in. If the Fast Flashing Red persists after several attempts, the battery condition is questionable.



Also in the trouble shooting guide, it mentions this:


Problem: Red Indicator Light Is Flashing While Charging

Solution:
A red flashing indicator light when charging indicates a selftest
error condition. Unplug the product and plug it in again.
Try this several times; if the indicator light continues to flash
red, unplug the GlowBuoy and take it to an authorized service
depot.

Battery indicator?

Hi there.
Sounds like the battery could be faulty.
The diagnostic procedures from the Dell User Guide are as follows:

Total Power Failure When Using a Battery
If an AC adapter is not connected to your computer, the computer's power source
is a battery. If the battery indicator flashes amber or is a steady amber, the
battery needs to be charged. If the battery is flashing green and amber, the
battery may be defective. To troubleshoot this problem, use the following
procedure.
1. Turn off the computer and peripherals, and disconnect them from AC power.
2. Reseat each installed battery by removing it and then replacing it.
3. Turn on the computer. Does the green power indicator light up?
Allow one minute for the computer to initialize its components before checking
for signs of power.
Yes. Continue to step 4.
No. Use the AC adapter to connect your computer to AC power. If the computer
operates normally when using AC power, go to step 7. If the computer does not
boot when using the AC adapter, see the previous subsection, "Total Power
Failure When Using the AC Adapter."
4. Does the battery indicator flash amber or show a a steady amber light?
Yes. The battery needs to be charged. Go step 5.
No. Go to step 7.
5. Connect the computer to AC power, and fully charge the battery.
For instructions, see the topic titled "Charging the Battery" in the online
System User's Guide.
6. As the battery charges, does the green battery indicator light up?
Yes. Go to step 9.
No. Go to step 7.
7. Is the battery indicator flashing green and amber?
Yes. Your computer may be in a hot environment. Charging the battery in this
condition may affect the life span of the battery. Continue to step 8.
No. The problem is resolved.
8. Disconnect the computer from AC power. Is the the battery indicator still
flashing amber?
Yes. You may have a defective battery. Continue to step 9.
No. The problem is resolved.
9. Remove the battery, and press its test button. Is the uppermost indicator in
the charge gauge of the battery flashing?
Yes. You have a defective battery. Continue to step 9.
No. The problem is resolved.
10. If a spare battery is available, fully charge it, and then install it in the
computer.
11. Turn on the computer. Is the power indicator off?
Yes. Your original battery is defective.

Good luck

Batt light flashes 4 red and 1 green over and over vostros laptop

Hi there. If your battery light is flashing 4 red and one green on the battery light indicator (as in the one next to the power and hdd led), then this is an indication that your battery is nearing the end of it's life, and it's time to get a new one. It will last a bit longer, depending on how much you use your laptop, but there will come a time when it won't work at all.

Red Flashing Icon

The icons from the left: 1. Power indocator 2. Hard Disk indicator --> it is a tube icon, not battery, but means hard drive. 3. Power Source indicator 4. Bluetooth indicator
The third from left means the power source indicator. Normally it is light green. If there is battery problem (can not charge or battery overload) it flashes amber/orange. If flashes red, it indicates that the battery power is low. You need to change the battery or connect the AC adapter.
