Description

The Energizer Industrial D LR20 is a 1.5V alkaline battery sold in a 12-pack, designed for high-drain professional and commercial applications. Each cell uses zinc-manganese dioxide alkaline chemistry to deliver sustained power output in devices that draw significant current over extended periods.

Designed for large torches, portable radios, medical instruments, emergency lighting and industrial equipment, the D cell format provides higher capacity than AA or AAA equivalents due to its larger internal volume. The 12-pack format suits environments where batteries are consumed regularly — workshops, care facilities, security operations, event production — and need restocking in bulk rather than retail 2-packs.

Energizer Industrial batteries are engineered for longer shelf life than consumer-grade equivalents, retaining charge for up to 10 years in storage when kept in their sealed packaging. This makes them suitable for emergency kits, backup lighting and seasonal equipment where batteries may sit unused for months between deployments. The cells measure 61.5mm diameter by 33.2mm height per industry-standard D cell dimensions, fitting any device rated for LR20 or D-size alkaline cells.

Frequently Asked

How long do these batteries last in storage?

Energizer Industrial D cells retain charge for up to 10 years when stored in their original sealed packaging at room temperature. This shelf life makes them suitable for emergency kits and backup equipment where batteries may not be used immediately after purchase.

What devices are these designed for?

D cells are designed for high-drain devices including large torches, portable radios, boomboxes, megaphones, medical instruments, emergency lighting, and industrial equipment. They provide higher capacity and longer runtime than smaller cell sizes in devices that draw sustained current.

Are these rechargeable?

No. These are single-use alkaline cells. Once depleted they should be recycled through a battery recycling programme rather than recharged. Attempting to recharge alkaline cells can cause leakage or rupture.

What's the difference between Industrial and consumer Energizer batteries?

Energizer Industrial batteries are engineered for longer shelf life, bulk packaging and commercial/professional use. They carry the same core alkaline chemistry as consumer equivalents but are optimised for environments where batteries are stocked and consumed in higher volumes.
