Plus some hefty solder joints to hold the prongs in place. Back in 2016, I tore apart a 3.0Ah pack I had laying around - that particular one had a bad cell group (dead short in a cell - that must have been exciting when it failed), so it was quite unusable and I couldnt really get much data on it. And Im not entirely sure I understand its point. On a dewalt 18v battery which is positive terminal? The exposed balance wires (coming from the center of each H interconnect) go into the board and are routed to the C1-C4 terminals in the center (since these dont handle nearly as much current, they dont have to be double height). I have no doubt that if Id run it down to the 12.5V mark, that extra 0.2Ah would have popped out - so this is absolutely a 6Ah pack! They are dead as granite.

To clean the corrosion from the battery terminal you need to neutralize it with a basic solution then remove the corrosion. This is a healthy pack. The time it needs to fully charged a SLA battery will depend on battery type, size and depleted state. Based on the lack of any other wires, its likely just a basic voltmeter that lights up the LEDs. That third contact is connected to an internal thermistor, enabling the charger to measure the battery temperature. Unfortunately, this one is really only monitoring pack temperature - not cell temperature. A bit of fiddling, and the BMS is clear! That this is higher than above is actually reasonable - the cells were warmer during this discharge, so will put out a bit more voltage. This is a bit lower than what Im used to (normally 3.6V per cell), but based on the datasheet, this corresponds roughly to a 30% state of charge (required for some newer shipping regulations). This pack cant do it. Fortunately, I have such a beast, warming up nicely in this picture.
