Please be aware that standard eGo batteries are basically all the same, some have monikers attached to them like "eGo-C" or "eGo-T" but the batteries themelves are the same, in general (usually) a "C" or a "T" or anything after the "eGo" signifies the cartridge/carto that some use on the battery, it is mostly useless in determining the type of battery. 

Most batteries have 5 click shut offs.  The batteries below are more for stealth, sneak vaping or for small storage as they hold a very small charge and will not generally "last all day" as larger batteries do.
