I don't like taking anything extra when I leave for work or anywhere else. A 12 hour batt, and an 3.5mL clear carto are enough to get me through most trips. I do have an extra of everything in my locker at work. JMHO

I take a spare battery and an empty carto with me to work. I have a charger and bottle of juice in the truck. On a ride I just take a fresh battery and 10ml (partly full) of juice. I don't carry nearly as much as I used to.
