Duracell Plus Power D LR20 Alkaline Batteries (6 Pack)

Duracell Plus Power D batteries are 1.5V alkaline LR20 cells designed for high-drain devices that require sustained power over extended periods. This 6-pack provides dependable energy for torches, portable radios, camping lanterns, large remote-controlled toys and other household devices where AA or AAA batteries are too small to meet the power demand.

Suited for both everyday household use and emergency preparedness kits, these D cells are formulated to retain charge during long-term storage, with a shelf life of up to 10 years from manufacture when stored at room temperature. This makes them practical for devices that sit unused for months between power cuts or camping trips. The alkaline chemistry provides a stable voltage curve across the discharge cycle, avoiding the abrupt power drop seen in cheaper carbon-zinc cells.

Duracell claims these Plus Power cells deliver up to 100% longer runtime than basic alkaline alternatives when used in high-drain applications, though actual performance varies depending on device type, usage pattern and temperature. The 6-pack format balances bulk purchasing with manageable storage — six D cells occupy roughly 200mm of drawer or cupboard space when laid end-to-end. Each cell weighs approximately 135g, giving the pack a total weight of 0.81kg.

What devices use D batteries?

D cells are commonly used in large torches, portable radios, camping lanterns, baby swings, large remote-controlled vehicles and some security devices. They suit devices that need sustained power over many hours but where rechargeable options are impractical due to infrequent use or emergency backup requirements.

How long do D batteries last in storage?

Duracell Plus Power alkaline batteries carry a 10-year shelf life from the date of manufacture when stored at room temperature in their original packaging. This makes them suitable for emergency kits and seasonal devices that sit unused for extended periods.

Can these be used in cold environments?

Alkaline batteries lose capacity in cold temperatures, typically delivering 50-70% of their rated performance at 0°C compared to 20°C. For winter camping or outdoor use in freezing conditions, lithium D cells perform better, though at higher cost.

Are D batteries rechargeable?

These Duracell Plus Power cells are single-use alkaline batteries and cannot be recharged. Rechargeable D-size NiMH cells are available separately if your usage pattern involves frequent discharge and recharge cycles, though they have lower initial voltage (1.2V vs 1.5V) and may not suit all devices.
