Description

The Energizer Max D LR20 is a 2-pack of alkaline D-cell batteries, each delivering 1.5V output for medium to high-drain devices. These batteries use Energizer's alkaline chemistry with a leak-resistant construction designed to prevent internal electrolyte leakage that can damage device contacts and battery compartments.

D cells are commonly used in large torches, portable radios, camping lanterns, boomboxes, and certain toys or outdoor equipment that require sustained power over long periods. The 2-pack format suits users needing occasional replacements for devices that take one or two D cells, or as a top-up for existing stocks. The Max range is Energizer's standard alkaline line, sitting below the Ultimate Lithium tier but above basic zinc-carbon cells for runtime and shelf life.

Each cell weighs approximately 150g and measures 61.5mm in height by 34.2mm diameter. The alkaline composition provides better energy density than zinc-carbon alternatives, meaning longer runtime per cell in moderate-drain applications. The mercury-free formula removes the heavy-metal content found in older battery formulations, making disposal less environmentally harmful when batteries reach end-of-life. Energizer rates the Max range for a 10-year shelf life when stored at room temperature, making them suitable for emergency preparedness kits and infrequently-used devices.

Frequently Asked

How long do these batteries last in a torch?

Runtime depends on the torch's LED output and driver efficiency. A typical 3W LED torch using two D cells might run 20-40 hours on continuous use. High-output torches with 10W+ LEDs will drain the cells faster, while low-power camping lanterns can run for 100+ hours.

Are these rechargeable?

No. Energizer Max D cells are single-use alkaline batteries. Attempting to recharge alkaline cells can cause leakage or rupture. For rechargeable D cells, look for NiMH (nickel-metal hydride) alternatives.

What's the shelf life?

Energizer rates the Max range for 10 years of shelf life when stored at room temperature in the original packaging. Shelf life reduces in high-temperature or high-humidity storage conditions.

Can I mix these with other brands or part-used cells?

Mixing brands, mixing alkaline with zinc-carbon, or combining new and part-used cells reduces performance and increases the risk of leakage. Always use matched pairs or sets from the same pack and replace all cells together when a device stops working.
