Sold in boxes of 15. These Trojan batteries are made by the same manufacturer that makes K2 cells. These are the cells that Trojan uses to build their packs. The cells have never been cycled and are overstock from a large project. Just $2 per cell, you can't beat this deal. Get them while they last!
Datasheet for these cells is the same specs as K2 3700mah cells, these just have the Trojan wrapper on them instead of the K2 wrapper.
