Duracell D Plus Power, Card of 2

Reliable Power for Equipment That Needs Extended Runtime

The Duracell Plus Power D battery is designed for electronic equipment that requires dependable power and longer operating times.

Using proven alkaline technology, each battery delivers a nominal voltage of 1.5V in the standard D / LR20 / MN1300 format.

The larger D-cell design makes these batteries especially useful for equipment such as powerful torches, radios and other portable devices where extended runtime is important.

Ideal for Yacht & Boat Equipment

Reliable portable power is essential onboard, especially for equipment that may be needed during maintenance, night operations or emergency situations.

Duracell Plus D batteries are suitable for compatible devices such as:

• Large flashlights and torches
• Emergency lighting equipment
• Portable radios
• Battery-powered lanterns
• Portable electronic equipment
• Measuring instruments
• Recreational equipment
• Toys
• Other devices requiring D / LR20 batteries

For yacht owners, captains and crew, keeping spare D batteries onboard ensures compatible equipment can quickly be returned to operation when batteries are depleted.

Always check the battery requirements specified by the equipment manufacturer before installation.

D / LR20 / MN1300 Format

The Duracell Plus Power D uses the internationally recognised D-size cylindrical battery format.

It may be identified under several common references:

D / LR20 / MN1300 / 13A

These references describe the same general battery size and help make it easier to find the correct replacement for compatible equipment.

Each battery provides:

Nominal Voltage: 1.5V
Battery Size: D
IEC Designation: LR20
Duracell Designation: MN1300
Chemistry: Alkaline Manganese Dioxide – Zn/MnO₂

Designed for Longer-Running Portable Equipment

The D battery format is commonly selected for equipment where a larger battery and extended runtime are required.

This makes Duracell Plus D particularly useful for:

• High-output portable torches
• Emergency lanterns
• Portable radios
• Warning equipment
• Large battery-powered accessories
• Equipment used for extended periods away from a fixed power supply

Onboard a yacht, these applications can be particularly important during maintenance work, night inspections or emergency situations.

DURACELL PLUS – 100% LIFE GUARANTEED

Duracell markets its Plus D batteries with the claim:

100% LIFE GUARANTEED*

This commercial guarantee is based on comparison with the Minimum Average Duration across 2021 IEC D-size battery tests.

Actual battery life depends on the type of equipment, electrical load, environmental conditions and usage pattern.

The important benefit is dependable alkaline power from a battery designed for applications where consistent performance matters.

Up to 10 Years in Storage

Duracell states that unused Plus D alkaline batteries can remain powered for up to 10 years when stored under ambient conditions.

This makes them particularly useful as backup batteries onboard.

A pack can be stored in an emergency or spare-parts locker so that replacement batteries are available even when the equipment itself is used only occasionally.

Practical Pack of 2

The Card of 2 contains two Duracell D batteries in one convenient blister pack.

Many devices requiring D batteries use more than one battery, making the two-pack a practical choice for both immediate replacement and onboard storage.

Ideal storage locations include:

• Yacht spare-parts lockers
• Emergency equipment lockers
• Engineering stores
• Crew supply areas
• Toolboxes
• Battery storage cabinets

Wide Operating Temperature Range

Duracell technical data for the MN1300 specifies an operating temperature range of approximately:

-20°C to +54°C

Recommended storage conditions are approximately:

5°C to 30°C

This broad operating range makes Duracell D batteries suitable for many different portable applications, provided that the equipment itself is also designed for the environmental conditions.

Why Choose Duracell Plus Power D?

Some onboard equipment needs more than compact AA or AAA batteries can provide.

The Duracell Plus Power D gives you a larger alkaline power source designed for devices requiring dependable operation over longer periods.

For yacht owners, engineers and crew, it is a useful battery size to keep available alongside AA, AAA, C and 9V batteries as part of a complete onboard battery inventory.
