Battery Heavy Duty D (R20) Kodak pack of 2 — primary zinc-carbon D cells

Kodak Heavy Duty D (R20) primary zinc–carbon batteries, pack of 2, are single-use D-size cells designed for low-to-moderate drain applications. Each cell provides the standard nominal voltage and steady discharge suited to devices where occasional power bursts are required but sustained high current is not necessary. The batteries come in foil packaging for individual protection and convenient storage.

Advantages

These Kodak Heavy Duty D batteries offer a cost-effective power solution for devices that do not demand high continuous current. The zinc–carbon chemistry delivers reliable performance in everyday use, with stable voltage for devices such as flashlights and radios. As single-use primary cells, they are ready to use from the package and do not require charging or maintenance.

Suitable for

• Flashlights and lanterns with low-to-moderate power draw
• Portable radios and clock radios
• Children’s toys and novelty electronics
• Vintage devices and household tools designed for D-size cells

Key specifications

• Cell type: D-size (R20) primary battery
• Chemistry: zinc–carbon
• Configuration: single-use (non-rechargeable)
• Packaging: foil-wrapped individual cells, pack of 2
• Intended use: low-to-moderate drain devices

How to use

Install each D cell according to the polarity markings in the device compartment, ensuring correct orientation of positive and negative ends. If a device requires multiple cells, use matched new batteries to achieve consistent performance. Remove spent batteries promptly and follow local regulations for disposal of single-use zinc–carbon cells.

Usage recommendations

Store batteries in a cool, dry place and avoid prolonged exposure to high temperatures. Do not mix used and new batteries or different battery chemistries in the same device. For devices with sustained high current demands, consider using batteries with higher capacity or rechargeable alternatives designed for heavy loads.
