1500 mAh Alkaline Battery - AA

  These are your standard 1.5V AA alkaline batteries from Duracell.
Don't even think about trying to recharge these. Roughly 1500mAh per AA cell.
Combine 4 to get ~6V peak, and ~4.8V as they hit their discharge curve.

Sold in single units. But if you order four at a time,
it makes it easy for us to package them.
