Rather strange to use a battery to power on a system, but makes sense now.

You got lucky getting them so early. I've rescued rained on and flooded machines in the past and it was a nightmare to clean them up. If I get lucky, they power up and work, but most of the time lots of components have to be removed and replaced.
