PowerPro Dynamite Autopower 300A battery charger. Appears to be NIB.

The battery will not charge in the sweeper. I can remove the battery and wire it to the power supply for charging and it will charge up and run the sweeper. So the power supply and the battery are both good. Obviously there is a circuit failure in the on board charging control. Anyone know a fix or a likely faulty component?

I had a shark handheld about 8 years ago and it developed the same problem. I examined the little circuit board inside but saw no visible indications that would isolate t. I want to recharge my Philips PET741 D/05 portable DVD Player. But when I push the plug into the charging point on the side of the player,at one point, as the plug goes in, there is a quick flash of red - but no more. The red charging light does not light up, and the player does not charge.

The plug cannot be held at the point where the sudden momentary flash takes place 1.With the AC power unit plugged in to the wall plug into your dvd player and wiggle it a little bit and see if the light goes on or off.

I now need to know from someone who's DC16 is working properly what voltage the battery should have when it is charged. I currently only measure 24.2V in mine.

Supposing there are 6 batteries in there with nominal 3.6 voltage each, which would add up to 21.6, I supposed one could charge with up to 25.2V (4.2*6) and once reach lower the voltage ke Does it stop working real fast? My Prosine 2.0 display panel displays Panel Fault: Memory error and the display error as well as all LEDs are off. The unit looks as if it has no power to it. I reset (power off.power on) the Prosine and all LEDs on the display (except for the back lit display) turn on for about 3 seconds then all go off again. I am able to use 120v RV Resort power and all 120v equip works. The Coach batteries do not charge and were low.

I charged the Coach batteries with an external charger. The charge works ye. I cannot charge my two year old electrolux pronto. I purchased a brand new hand held vacuum for it, but even the new one does not charge. When I plug in the cord nothing happens.

If I turn on either the long handle or the portable unit within the long unit, the blue charging light comes on for a few seconds, then out. This tells me that the circuit is intact without a broken wire somewhere. I took it all apart carefully and could see nothing broken or out of place. On re-constructing it, it It must be the charging transformer. We have already ruled out the vacuum unit. Unfortunately the transformer is not a serviceable part, and will need to be replaced. I have a Roomba Discovery.

In the past, I had to replace the charging dock. Then the battery died so I did not use it for two years. I finally bought a new battery and used the Roomba. It worked great. It did not find the docking station, and died. I have been charging it and the red light pulsates, but after 16 hours, it still is not charged.any ideas? Turn your robot over and clean the charging contacts with the eraser end of a common pencil.

Then Charge it and you should be up and running again. Regards, Joe. Battery charge I just purchased a new battery pack insert for my Roomba, Replacement was a breeze and it now works great. My question is; The last battery I bought ( not from you) was a full cased roomba battery pack that didn't last a year. Roomba says leave the r Roomba charging all the time so it's ready when you need it, and that's nice but I feel that leaving it charging like that it will kill the battery faster as it is always warm to the touch. These battery's should last at least 5 Dave you are correct. You should never over-charge anything like a Roomba, Cel Phone, etc.
