Ryobi BCL14181H: Why doesn't my charger work?

Wed, 08 Apr 2026 17:50:12 -0700

The charger for my Ryobi One plus BCL14181H doesn't work. I took to pieces it and saw that one of resistance and transistor were burned. I replaced the resistance, but i can't see the number of transistor. It would be good if someone makes photos of sceme and of transistor and writes the number of this transistor.

Thanks for all who will aid with this problem.

Ryobi BCL14181H: Trying to repair my Ryobi BCL14181H battery charger

Wed, 02 Jul 2025 11:06:43 -0700

I have a BCL14181H battery charger (Ryobi) that does not charge. No blown parts. I am having trouble identifying components. Does anyone know the component number for U5? It is a 20 pin SMD chip. Also there are some components that look like an SMD resistor but appear to be jumpers. they are labeled RJ1, etc. Component U4 has what looks like T8L05 stamped on it. Anyone have an idea what it is?

I tried it with a battery that is at 16.5 volts and it doesn't work. I can put the battery in a known good charger and it charges up.

Ryobi BCL14181H: What is the part number for IC U5 in my Ryobi BCL14181H Battery charge

I have two identical chargers that don't work. The red light just keeps flashing. No visiable damage on the board. I am trying to find out the part numbers for several of the components. U5 is a 20 pin IC with no visiable markings. Does anyone kow what to part is?

Ryobi BCL14181H: Need help with Ryobi charger

Wed, 02 Jul 2025 07:36:49 -0700

I have a BCL14181H 18v charger that doesn't charge. Diode D9 which appears to be in parallel with R25 is shorted (maybe). What is the part number and which way does the cathode go? I do not have any blown components but the unit will not charge a battery. This is a Ryobi charger.

R25 is a 47 ohm resister.

Sorry, the two connect to U1 (the switch mode controller) through R24.
