First, you need to make sure your power adapter is providing enough power to both run the laptop & charge the battery. A very good way to do this is to compare your laptop voltage & ampere requirements (written on a sticker on the bottom of the laptop) with the voltage & ampere ratings of the power adapter. Voltages should be the same, or the power adapter's voltage about up to 0.5 volts more than the laptop's voltage rating. Amperage of the power adapter should be at least equal to or greater than the laptop's rating. It should never be less than the laptop's rating, or else the power adapter will be providing insufficient amperes to charge the battery. Of course, the power adapter's nominal amperage might be ok, but it degraded on usage. You can verify this by testing using a good or new power adapter.
If the battery did not charge using the new power adapter, take the battery off the laptop, & using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self, then put the battery back into the laptop & try again.
If this still did not resolve the problem, then the battery itself could be bad. Try it on another laptop, or try a good or new battery in your laptop.
If this did not work, there might be a possibility that the charging circuitry on the laptop's motherboard is defective & needs servicing. In order to do this, the laptop needs to be disassembled & the motherboard checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether

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.

Red blinking light


Hi, Ephraim. The flashing red light indicates that the device is showing "low battery". It could be that the LG phone charger fits the charging port on your bluetooth headset but it is not compatible with your device. In order for you to know that it is charging, the device should show a steady red light(means charging).
Please take a look at the table reference below.

•With the Charger Plugged In

Note: After 20 minutes on a call or of inactivity, the light stops flashing to conserve power, but the headset remains on

Hope that'll help you in some way.

Motorola cellular w376g, battery won't charge


If possible test with another charger like a car charger if you have one
also try removing the battery plug in the charger and put the battery back in (don't touch the contacts/gold pins)


if it works with other chargers then the charger is bad


if it doesn't work with other chargers charging port/battery/phone is bad

Red and green flashing lights on 18v lxt charger


Batteries don't always look degraded but if they've been in use for a while or have a bad cell, they will show up bad on the charger and it won't charge them. The only way to test the batteries is to try to charge them on another charger. If the batteries show defective on another charger, they are bad and you'll have to replace them. Also try to charge some batteries you know to be good on your charger to see if it's the problem. If your batteries charge on another charger, your current charger is bad and they don't have any replaceable parts in them so you'd be looking at replacing it.

I'm borrowing a Jet 3 Ultra from the local Am. Legion for my Mom to use. They know nothing about it except they were told it had a new battery. I plug it in and all the LED's light up with the...


The batteries need charging and when you plug in the charger and the power is on the lights wil flash indicating that the charger is plugged in. Now look at the rear of the chair near where the charger cord plugs into the chair and you should see a voltmeter. With the charger plugged in the voltmeter will indicate about 5-6 amps and after charging overnight the voltmeter should be reading 0 amps. If when you plug in the charger cord and the voltmeter indicates 0 amps then I would suspect that the charger is not working or that the fuse is blown in the charger circuit. The only way to see if the batteries charge would be to borrow or find an offboard charger that will plug into the charger port located under the front of the joystick and after charging for 10-12 hours see if the battery level lights show full charge Hope this helps

Battery discharge quickly, I have replaced new batteries and module control and problem still exist.


Don your charger is probably not charging the batteries. When you charge your chair overnite the charger should have a red and green light showing charge complete. When you first plug it in the lights should be red and yellow. If you are getting a red and green light when you first plug it in then there is a problem with the charger or with the charging circuit to the batteries. You should have a charger port on the battery box try plugging the charger into that port and see if you can get the batteries charged. When you do you should have a red and yellow light on the charger changing to red and green when fully charged. Hope this helps

I have the SSC-1500A battery charger and the yellow light keeps flashing. The yellow light is the charging light.not sure why


This unit will assume a battery voltage less than 1.5 volts means the battery is sulfated. The flashing yellow light means it has gone into 'desulfate' pulse mode using pulses of high voltage to try and convert the lead sulfate back into sulfuric acid and lead plating. It will do this for about 8 hours on the charger I have. If the voltage has not raised to a level that can can accept a normal charge it will abort the pulse mode and stop trying to charge it. You will need to unplug and replug in the charger to try again. Always check the temperature of the battery while charging it and especially if the charger is in pulse mode. Stop charging if the battery is hot. *always wear safety gear*

ROOMBA POWER


Is the power light pulsing when on charger? Make sure you have the battery in correctly and snapped securely into place. Only charge on the home base, do not plug in directly.
