Just out of curiosity we ordered a couple 510 mega batts from Cignot. Holy crap!
These things are a full inch longer than the standard 510 manual battery and they last and last. My wife used to take a couple of batteries to work with her but now she just takes the mega battery and a regular as back up in her PCC (but never needs it). Of course they won't fit in the PCC but it doesn't really matter.
They feel a little strange to me but they give the results. Kind of makes me feel like I'm holding a magic wand. Guess I am. IMO, the mega batts are worth the few extra bucks.
