Product Details

The D size R20 Carbon Zinc Battery is a large-format cylindrical 1.5V dry battery built for devices that need a bigger cell, more stored energy and easier handling. With a standard D form factor of 34.2 mm in diameter and 61.5 mm in height, it fits the full-size D battery compartments used in gas appliances, high-power flashlights and large portable radios.

Each cell uses a carbon zinc electrochemical system housed in a PVC-jacketed cylinder. The battery is supplied as a primary (non-rechargeable) cell and is available in OEM colors, with brand options under VE Powery / OEM, so brand owners can match the cell to their own product identity. Free samples are available for evaluation before volume ordering.

WHY THIS PRODUCT 04

Product Advantages

  • Large Standard D Format: A standard D size of 34.2 mm x 61.5 mm fits the full-size D compartments used in gas appliances, large flashlights, emergency lights, large radios and electronic door locks.
  • Stable 1.5V Output: The carbon zinc system outputs a stable 1.5 V, which suits devices designed for standard D alkaline or carbon zinc cells.
  • Higher Capacity Format: The larger D body houses more active material than AA and AAA cells, making it the right choice for appliances that run longer per cycle or draw more current.
  • PVC Jacket Construction: The PVC jacket protects the cell body during storage, transport and insertion, keeping the surface clean and easy to handle.
  • Cost-Effective, Maintenance-Free: The cell is non-rechargeable and requires no charging cycle or charger, keeping total cost of ownership predictable for appliance makers and retailers.
  • OEM Color & Branding: OEM color and brand options (VE Powery / OEM) let buyers align the cell with their own label and packaging design.
WHERE IT WORKS 05

Typical Applications

  • The D size R20 carbon zinc battery is designed for large-format, often intermittent-use applications. Typical scenarios include:
  • Gas Appliances: Gas stoves and gas water heaters, where a single D cell powers the ignition and control circuit over long service intervals.
  • Large Flashlights & Emergency Lights: Large flashlights and emergency lights used for household, workshop and outdoor lighting backup.
  • Large Radios: Large radios and portable sets with a full-size D battery compartment.
  • Electronic Door Locks: Electronic door locks that accept a D size 1.5 V cylindrical cell and do not require rechargeable chemistry.
  • Other Large-Format Devices: Other appliances that are designed around a standard D 1.5 V cylindrical cell.
