Overview
The Energizer MAX D is a 1.5 V alkaline cell in the large D size, sold here as a pack of two. Energizer is one of the two best-known battery names in the world. The brand is owned by Energizer Brands, LLC of St. Louis, Missouri, and MAX is its everyday alkaline range, positioned above the budget zinc-carbon cells and below the lithium Ultimate line.
D cells are the biggest of the common household sizes. That means more active material inside and a long run time in anything that draws steadily: a large camping lantern, a spotlight, a portable radio or a game-camera feeder. The ANSI name is D and the IEC name is LR20. You will also see it called E95 or a number 13 cell.
The cells in this pack are the MAX range with the red and silver swoosh label. The casing is marked with a polarity warning in several languages and is stamped as made in China for Energizer Brands. They are a primary (single-use) chemistry, so they should never be recharged.
Key Features
- Alkaline manganese dioxide chemistry gives a steady 1.5 V output, so torches stay bright for longer than on zinc-carbon cells.
- The large D size holds far more energy than AA or C cells, which suits lanterns, spotlights and other high-drain gear.
- A sealed steel can and the standard flat-negative and button-positive ends fit any D-size holder.
- Long shelf life when stored cool and dry, so a spare pair can sit in a kit bag or vehicle until needed.
- The twin pack suits two-cell torches and radios, with no need to buy a large bulk pack.

Fit & Compatibility
These cells fit any device that takes D, LR20 or 13A batteries. Common firearm and outdoor uses are large torches and spotlights such as Maglite-style 2D and 4D models, camping lanterns, portable radios, and game feeders. Always check that the polarity marks (+/-) in the battery compartment line up with the cell ends.
Do not mix old and new cells, or different brands, in the same device. A weak cell drags down the whole set. NiMH D cells are interchangeable in most devices, but their lower 1.2 V rating can dim some torches.
Care & Maintenance
- Store in a cool, dry place away from direct sun, and keep the cells out of a hot vehicle cab.
- Replace all cells in a device at the same time.
- Take cells out of gear that will be stored for months, as old alkaline cells can leak.
- Never recharge, open, short or burn the cells, and keep them away from children.
- Dispose of used cells at a battery recycling drop-off.
FAQ
Are these rechargeable? No. They are single-use alkaline cells, and the warning on the label says not to recharge them.
Is LR20 the same as D? Yes. LR20 is the IEC name for the D size, and they are fully interchangeable.
How many are in the pack? Two cells, which is the right number for most two-cell torches and radios.
