Amazon Basics D Cell Alkaline Batteries

Amazon Basics D Cell Alkaline Batteries

Reliable 1.5V D alkaline batteries for high-demand devices that need long, steady power. Ideal for large flashlights, camping lanterns, portable radios, motion sensors, signage, and select toys or instruments. Not rechargeable.

At a Glance

When to Choose These

• Powering large lanterns and flashlights for extended outages or camping.
• Running portable radios, PA systems, or motion-activated lights where steady output matters.
• Stocking emergency kits and facility maintenance carts where long shelf storage is needed.
• Keeping simple, cost-effective power on hand without charging equipment.

Consider Alternatives If

• You want rechargeable power: use NiMH D cells or AA-to-D adapters with high-capacity AA NiMH (if your device allows).
• You operate in very cold weather (below 32°F/0°C): lithium primary cells generally hold voltage better in extreme cold (confirm device compatibility).
• Your device specifies a different chemistry or voltage: follow the device manual.

Pack Options

Buy small packs for quick replacements or bulk for teams and facilities. Common options include 2- or 4-packs for households, larger consumer multi-packs, and bulk sleeves or master cases for organizations. Choose based on monthly usage and storage capacity.

Typical Performance Examples

• LED camping lantern (300–500 lumens): about 10–30 hours on high, longer on low.
• Large flashlight: often 15–40 hours depending on brightness and mode.
• Portable AM/FM radio: roughly 50–100 hours at moderate volume.
• Motion sensor light: several months of typical use, depending on triggers and brightness.

Actual runtime varies by device, settings, and temperature.

Storage and Handling

• Store cool and dry, away from heat and direct sun. Keep in original packaging or a non-conductive container.
• Do not mix old and new batteries or different chemistries in the same device.
• Remove batteries from devices stored long-term to reduce leak risk.
• Recycle or dispose according to local regulations; do not incinerate.

Compatibility Notes

• Use only in devices that specify D (LR20) 1.5V alkaline batteries.
• Do not attempt to recharge alkaline batteries.
• Check device polarity and ensure clean, dry contacts for best performance.

FAQ

• Are these rechargeable? No. They are single-use alkaline cells.
• What is the shelf life? Alkaline batteries typically hold up well for multiple years when stored properly. Check the package date code and rotate stock annually for critical use.
• Can I mix brands, sizes, or chemistries? No. Mixing can cause leaks, reduced performance, or device damage.
• Do bulk packs perform differently? The cells are the same; bulk packaging reduces waste and cost per unit. Verify freshness by checking date codes.
• How do they perform in cold weather? Alkalines lose capacity in the cold. Keep spares warm and consider lithium cells if the device supports them for sub-freezing use.
