$5.99 is not really the same as the cost of a new cell… Yes I am getting 2 for $12 but the discount for purchasing multiples should be taken in to consideration. the cheapest you will find a single cell for sale is $8.50-$9.

The auction is for 2 cells, so one would assume that both cells would be covered for that price…. which I would interpret as meaning that should both batteries fail both would be eligible for replacement.
