A few months ago, I had a Duracell battery leak inside my Apple wireless keyboard. The battery basically fused to the inside of the the tube and couldn't be removed, so Duracell sent me reimbursement for the keyboard and a coupon for a free Duracell Procell battery pack up to $10 in value. Unfortunately, I'm not sure there's any place where I can actually use the coupon. Does anyone know of a place that sells Procell batteries? It's actually a generic barcoded coupon with no picture on it that says: "Duracell Procell Valid on ONE Duracell Battery Pack, any count, up to $10.00" so I don't know if I should just try it on a regular pack of Duracell batteries or call up customer service and ask them for a new coupon for regular batteries.
