An Internet search suggests that the Bosch BC130 has a ridiculously short lifespan and those of us that have braved opening the case discovered that R3 was burnt to a crisp and the color codes unreadable. Some of the reviews here on Amazon might also suggest that Bosch has made no attempt to correct an obvious design flaw because the new chargers fail just as fast; and good luck finding a schematic on their web site! This tells me Bosch is not taking care of their customers, shame on them!
Having a background in electronics is a pretty handy skill to have and one that has carried me well throughout the years. Fortunately, you don't need to be a electronics wiz to attempt to repair this charger, just a little patience, soldering tools (iron, solder, wick), and a new 180k Ohm resistor. Hence the title of this review: R3 = Brown Gray Yellow Silver = 180k Ohms +/10%.
Since this is supposed to be a review I won't go into detail on how to repair the charger since I've already given enough information for those that know what to do with it. I also can't guarantee that replacing R3 will fix it since I haven't tried yet. I have two possible theories as to why R3 burns up, either it's undersized (R3 appears to be 1/2 watt, I recommend buying a 1-watt +/5%), or something else went wrong in the circuitry such as a voltage regulator. Whatever the case, I have a lot of home projects to do this Summer and won't get around to fixing my old charger for some time. If someone uses this information to successfully repair their charger it is my hope that they leave a comment so that others can benefit.
Btw, R3 sits between two very large electrolytic caps. You WILL want to SAFELY DISCHARGE them before doing any work on the unit because they can give you quite a jolt. You have been warned!
As for the quality of the BC130 I can honestly say that my original lasted less than three years and I am disappointed about that. In contrast, the Bosch replaced a Craftsman cordless drill that served me well for over 12-years. The BC130's construction, the quality of the circuit board and components appears to be very high, it's just too bad they don't last.
I own several Bosch power tools most of them corded and they are absolutely outstanding products! However, based on my experience with the BC130 I will look elsewhere for my cordless tools from this point forward.

The charger charges fine....but it is hard to get the battery off the charger....very annoying .You have to push down on charger ,while pulling up with your other hand. Or step on the charger while pulling squarely up ....

Arrived quick, better charger than my original as it fully charges in about 30 min. Worth the price, other option was trashing a perfectly good cordless drill because my charger was obsolete.Save 49% Off
Bought this charger as a replacement for my cordless drill 2 years ago. It has had pretty light use, but no longer works. Looking at other reviews, this seems to be a very common issue for this charger. I won't be replacing the charger (for the third time) and will instead buy a drill from another brand.

This is exactly what is wrong with mine also. Other bad components not know as well. How did you arrive at the value of R3? Mine is burnt beyond reading it.
You nailed it. Exact same problem with mine. I just fixed it using a 330K and 470K in parallel to replace the original 180k. There is 300 volts across this resistor in operation, so the 180k was seeing half a watt, which is probably what cooked it as it appears to be a half watt resistor.
