I had that happen 10 years ago. Lots of the traces are already silver rivers of solder, painstakingly put down. Did some heavy cleaning this time around. Hoping for the best. If the acid made it down into the fiber of the PCB then I guess I will be putting in my order with Kiwi Technics in around 6 months. This whole thing is my own stupid fault. Why oh why did I put another Varta back in this thing in 2009???? On 29.01.19 16:26 , RJ Krohn wrote: > I restored a Polysix once with battery leakage.
