Re: battery not charging

The charger may be bad. The red light shows that power is applied to it. So usally, unless the light itself is bad, no red light, no power.

When I put the battery on the charger the light on the charger stays on for little awhile the it starts to blink, but when I try to use the battery it is not charged. So I am not sure if I need a new

Hi there! It sounds like you have our Linx stick vacuum or hand vacuum model. Plug only the charger into an outlet, the blue light on the charger should flash once. If the light on the charger flashes once then the charger is fine. Try resetting the battery by following these quick steps below.

1. Remove the battery from charger or cleaner
2. Unplug the charger
3. Insert the battery into the vacuum and turn the unit on for 30 seconds (even if it has no power)
4. Remove the battery
5. Plug the charger into an outlet, make sure the light on charger blinks blue once.
6. Insert battery into charger

The light should be a solid blue, indicating the battery reset worked. If so, allow the battery to charge for 3-4 hours, completely deplete battery on your next use and re-charge. If the light on the charger is still blinking, your battery will need to be replaced. I have included a link where you may go to purchase a replacement battery if needed. Hope this helps!

New Roomba Battery Not Holding Charge - charged once then died

It is possible for the charging system inside the roomba to call it quits. What I did to remedy this, since my roomba was out of warranty and I did not want to scrap it, was to buy a charging base on ebay. This charging base accepts different types of roomba batteries and even the scooba battery. The inconvenience is if you have a newer model roomba that has the battery inside, then you will need to remove the screws on the bottom plate to remove the battery. Hope this helps.

Should the red light on my 15.6v dustbuster turn green when it's fully charged? It doesn't.

I had the same issue, then i just found the manual, in charging part, it says:"The charging indicator will be lit as long as the
appliance is connected to the plugged-in
Also it says:"While charging, the charger may get warm, this is
perfectly normal and safe. It can remain on
charge indefinitely without damage or danger. It
is not possible to "overcharge" the battery cells
with the charger provided"

Dirt devil doesn[t hold charge

Try running the battery all the way down by letting the vacume run in a corner or another room and even when it stops leave it on for a hour to drain the battery. Then shut the switch off and try charging the battery. Make sure the charger is putting out enough volts by looking at the rated output of the charger and while it is plugged in check it with a volt meter. If it does not hold a charge and the charger is putting out the right voltage you need to purchase a new battery for the vacume

New battery. Charged for 24 hours. Light is green, but after 20 seconds light turns red and it stops.

There's a chance that the battery you bought is bad. There's a greater chance that the problem is with the charger. If you're using the dock to charge, try plugging the charger directly into the roomba just to rule that out. If that doesn't fix the problem, I would try borrowing or buying a new charger, and see if that works. If a new charger and new battery don't solve the problem, the problem must be with your roomba itself.

My iRobot scooba won't turn on after a full charge

Do you have the charger terminal, or do you have the charger that you have to take out the battery and charge. Because I have found that my base terminal charger works better than the battery charger that needs the battery to be removed to charge.If you have the terminal charger and the power light is green when it is in the charger I would start from the terminal

Is not charging - no red light

Yes, it can be replaced. Can be ordered from Black & Decker. Some people would say it's worth fixing others would not. Don't know cost of battery -- probably under $20.
