Duracell Plus Power AAA Alkaline Batteries - 10 Pack

Duracell Plus Power AAA batteries are 1.5V alkaline cells designed for everyday devices that run on AAA/LR03 power. Each cell uses Duracell's alkaline chemistry with Power Boost Ingredients — a formulation intended to extend runtime in moderate-drain devices compared to standard alkaline cells. The 10-pack format suits households stocking remotes, torches, clocks, wireless keyboards and similar devices that cycle through AAA batteries regularly.

These batteries fit any device marked AAA, LR03 or MN2400, covering TV remotes, children's toys, kitchen timers, bathroom scales, wireless mice, small torches and LED bike lights. The alkaline chemistry delivers consistent 1.5V output across the discharge curve, which means devices maintain stable performance until the cell is depleted rather than gradually dimming. Duracell rates these cells as leak-resistant when stored or used according to manufacturer guidance, reducing the risk of corrosion damage inside devices left unused for extended periods.

Each cell measures 44.5mm length by 10.5mm diameter, the standard AAA footprint. The cells are mercury-free and cadmium-free, complying with UK battery disposal and recycling regulations. Duracell recommends storing unused cells in a cool, dry location away from metal objects that could short-circuit the terminals. Once depleted, the cells should be recycled via local battery collection points or retailer take-back schemes.

What devices are these batteries suitable for?

AAA alkaline batteries suit moderate-drain devices including TV remotes, wireless keyboards and mice, clocks, bathroom scales, kitchen timers, children's toys, small LED torches and bike lights. They are less suitable for high-drain devices like digital cameras or motorised toys that cycle batteries quickly — those benefit from lithium or rechargeable cells.

How long do these batteries last?

Runtime depends on the device. In a typical TV remote with infrequent use, a set of AAA alkalines can last 6-12 months. In a high-use wireless mouse or a child's motorised toy, expect weeks rather than months. Duracell's Power Boost formulation extends runtime compared to their standard alkaline range, but exact duration varies by device power draw.

Are these batteries rechargeable?

No. These are single-use alkaline cells and must not be placed in a battery charger. Attempting to recharge alkaline cells can cause leakage, overheating or rupture. For rechargeable AAA batteries, look for NiMH (nickel-metal hydride) cells.

What is the shelf life?

Duracell alkaline batteries typically retain 80% or more of their capacity after 5-10 years of storage in cool, dry conditions. Check the 'best before' date printed on the pack or individual cell wrapper for the specific batch you receive.
