When I right click with a battery in hand to charge my mining drill and I am in range of a block such that my hand swings, the battery drains to 100 EU and does not discharge further, but still allows me to charge my drill. I have tested this in 2 separate worlds, both times with the normal mining drills and the bug occurs. Anyone else has experienced this issue?
As for the versions of ML/MLMP/Forge/IC2 I have installed, I have the latest versions as I just downloaded and installed them today. I also have Buildcraft installed, could that have caused the problem?
