[BUG?][1.4.3 SMP] Nano-saber not discharging?

Ok, so i've had a Nano-Saber in SMP for a while and I just noticed something. I've only had to charge it the once. It hasn't lost any power since then despite occasional use. (yes I do turn it on before I use it)

It can also use lappack energy.

Ah.. didn't know that as the wiki wasn't that updated last I checked. explains the extra power draw when I was exploring that cave.
