The Amazon battery just has that reverse polarity (I think, not confirmed) issue. So a multimeter should let you check that, compare pin-out with the original battery. Here is the pin-out & voltages for the original battery… [image] Red is positive 16.28v (4.07v/cell) in reference to the black and white wire. The voltage will vary, the max is 16.8v, the minimum about 12v. Black is assumed to be negative/common wire. White is assumed to be a signal wire that is “pulled-low”. Since Black+White…
