Leaking RTC batteries

[stasheck]

I thought I should share: I have a bunch of B3s, and I discovered that in all of them the RTC battery leaked - which may lead to damage to PCB.

You need to open B3, remove the (very small) screw holding PCB, replace the LR44 battery (clean up if it already leaked) and you'll be good to go again.

clean contacts...
Even better change it for a Silver-oxide (SR44)
