This is the charger, its getting a reading from the battery that its charged when it isn't. I don't know exactly how that charger is wired but, to be suroe it is the charger, as I have had similar problems beforehand.
Testimonial: "Brilliant! thanks very much for the very prompt reply - well impressed!"
robin , i had the same exact problem with my charger , and it kept getting worse first it was like 15 min then 10, 5 till it was just a minute of charging. I disassembled the unit and it was a leaking capacitor. I changed it and it worked fine. it costs only a few cents! Good luck
Which one of the four capacitors did you change?
I changed the 220 uF cap, and now it works:D thanks for the guiding:D on the pcb its called C1.

The change of capacitor 220uF solved the problem!
Thank you for your help!

Johan... I don't even know what a capacitator is... Could u please provide a link to the exact product I need to buy, and post more in depth instructions, please? I would appreciate it!
I have the same problem and don't know a capacitor from a quark. Please, more detail and instruction if you would. Thank you.

when changing Caps you can gradually step them "up", this will allow for greater capacitance and keep the unit from having the same issue. In this case, I would recommend a 250-280 @ 25v.

220uf 25v capacitor replaced and my Dremel is charging away quite the thing now.
Thanks for the heads up!!!!
Hi I have same problem. But whar volt is the 220 uF capacitor. As far I can see there more than one 2220 uF. One is 16v and other is 25v. Mayby one af them is an other component, but I can't see the difference.

Changing the 220uF capacitor helped me.
How to identify the problem: Have a look at www.badcaps.net
and this photo from them.
Had exactly the same problem with the same resolution. Maybe Dremel was sold a batch of dodgy capacitors?
Thanks, but HOW do I find the capacitor? Got the base unit apart but don't know which is the capacitor?????

How can you check if the cap i leaked?

Im wondering if the problem is related to a broken battery or a leaked capacitor.
You can see if it is concave or convex on the top. It should be concave (compare to other capacitors if you are uncertain). The change is very easy and the component it self costs around 0,2 Euros so even if you can't se if it is leaking change it and try! Much cheaper and easier than sending it for repair. If you do not know how ask a friend that has any basic knowledge in elektroniks and he/she will be able to help you. I fixed it and I havn't used my electronics skills since school 20 year ago... :-)
Make sure you get an electrolytic type capacitor and observe the polarity. Another charger working again now thanks to the advice above.

I would contact Dremel.com and talk to their tech department about a warranty repair for this tool.

Change the capacitor 220uF and it will most certainly work again. I got the idea from FixYa and it solved my problem!
Easy to change just 2 soldering points and a component costing around 0,2 Euros. If you do not know how to operate a soldering tool ask someone for a quick assistance. The switch takes around 2 min (1,5 min to open the charger and 0,5 min to change the component!).

I purchased a new charger from their spare parts store (available at least in Germany) and that solved the problem for me.
On my charger the same thing happened. I changed the capacitor of 220 micro Farad 25 V and returned to work. Thank you very much. Here from the city of Joinville in Brazil.?
