Procell is the contractor and facilities-maintenance line of Duracell, sold in bulk pack sizes for cost-per-cell savings over retail Coppertop.

Use Tip: Procell alkaline cells are designed for low- to moderate-drain professional devices. For high-drain photo, flash, or power-tool applications consider Duracell Procell Intense Lithium or rechargeable NiMH. Always replace all cells in a device at the same time and never mix battery brands or chemistries.

Storage Note: Store at room temperature in original packaging away from metal objects. Refrigeration does NOT extend alkaline shelf life and can cause condensation that shortens it.
