Description

The Energizer Max D LR20 is a 1.5V alkaline battery designed for medium to high-drain devices including torches, portable radios, camping lanterns, children's toys and smoke alarms. This 4-pack delivers sustained power over extended periods, reducing the frequency of battery changes in devices that run continuously or cycle on and off throughout the day.

D-size batteries are primarily used in devices that require higher capacity than AA or AAA cells can deliver. The LR20 chemistry provides stable voltage output across the discharge cycle, making these batteries suitable for devices that draw moderate current over hours or days rather than minutes. The 4-pack format suits households and workplaces where multiple D-cell devices are in regular use, or where keeping spares on hand reduces downtime.

Each battery uses Energizer's leak-resistant construction, which reduces the risk of corrosion damage to battery contacts and device internals during storage and use. The Max range sits between Energizer's entry-level Power and premium Ultimate Lithium lines, offering a balance between upfront cost and run time that works for most everyday applications. The batteries are mercury-free and can be disposed of with household waste in the UK, though recycling through battery collection points is preferred.

Frequently Asked

How long do these batteries last in a torch?

Run time depends on the torch's power draw and LED configuration. A typical LED torch drawing 200-300mA will run for 15-25 hours on Energizer Max D cells. High-output torches with multiple LEDs or older incandescent models will have shorter run times.

Can these be used in smoke alarms?

Yes. Many mains-powered smoke alarms use a 9V backup, but standalone battery-powered models often take D cells. Check your smoke alarm's manual to confirm the required battery type and replacement interval.

What's the difference between Max and Ultimate Lithium D batteries?

Ultimate Lithium batteries offer longer run time, better performance in extreme cold, and a 20-year shelf life compared to the Max alkaline's 10-year shelf life. For everyday indoor use in the UK, Max alkaline cells provide sufficient performance at lower cost.

How should unused batteries be stored?

Store in a cool, dry location away from metal objects that could short-circuit the terminals. Energizer Max batteries have a 10-year shelf life from manufacture when stored at room temperature, retaining approximately 80% of their original capacity after this period.
