Wow.  Another transformer, some non-power handling diodes, lots of capacitors and a couple of ICs!  A friend suggested the rest of the components are a switching power supply.  And the other thing to note is the three output leads (red, black and white) to the battery.<\/p>\n<p>A replacement charger is in the $140-200 range so cobbling together something that will charge would be very nice!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This is a 2-3 year old ryobi 40v lithium battery charger.
