Battery D (R20) Duracell LR20/D/MN1300 — pack of 2 alkaline cells

Duracell D (R20) LR20/D/MN1300 alkaline batteries in a pack of 2 are full-size single-use cells designed to deliver stable voltage for medium to high drain devices. These D cells provide a reliable disposable power source suitable for equipment that requires longer run times than smaller battery types can provide. The pack contains two standard D-size alkaline cells compatible with common devices that accept R20/D batteries.

Advantages

These Duracell alkaline D cells offer consistent voltage output and are optimized for applications that demand continuous power over extended periods. Their robust chemistry and construction reduce the need for frequent replacements in devices with moderate to high energy draw. As single-use primary cells, they are ready to install and provide predictable performance across a wide temperature range and a variety of household and portable equipment.

Suitable for

• Flashlights and torches requiring long runtime
• Portable radios and boomboxes
• Large toys and ride-on electronics
• Camping equipment and lanterns
• Some medical devices and measuring instruments designed for disposable cells

Key specifications

• Cell size: D (also known as R20)
• Chemistry: Alkaline manganese dioxide
• Configuration: Single-use (primary) cell
• Quantity: Pack of 2 cells
• Typical use: Medium to high drain applications
• Nominal voltage: 1.5 V per cell (standard for alkaline D cells)

How to use

Install each D cell in the device observing polarity markings (+ and -). Ensure contacts are clean and free of corrosion before inserting the batteries. Replace both cells at the same time to maintain balanced performance when two are required. Dispose of used alkaline batteries following local regulations and recycling guidelines; do not recharge, puncture, or incinerate single-use cells. Store unused batteries in a cool, dry place away from metal objects that could short the terminals.

Usage recommendations

For best results in high-drain devices such as powerful torches or motor-driven toys, check device documentation for recommended battery types and consider replacing both D cells together to avoid uneven discharge. Keep spare packs available for extended outings, and recycle spent batteries where facilities exist.
