Description

The Energizer Max AAA is a 1.5V alkaline battery in the standard LR03 size, sold here in a 12-pack. Each cell uses an alkaline zinc-manganese dioxide chemistry that delivers consistent voltage across a discharge cycle, making these batteries suitable for both low-drain devices (remote controls, wall clocks, smoke alarms) and moderate-drain devices (wireless mice, LED torches, children's toys).

Designed for household and workplace use, the Max AAA fits any device specifying AAA, LR03, or MN2400 batteries. The 12-pack format provides spares for multiple devices without needing frequent repurchases. Each battery carries a 10-year shelf life from manufacture date, allowing bulk purchases to be stored in a drawer or toolbox without degradation. The leak-resistant construction uses a seal design that minimises the risk of battery acid damaging device contacts during storage or use.

The Max range sits between Energizer's entry-level Power and premium Ultimate Lithium lines, balancing cost per cell against capacity. For typical household use — a TV remote drawing 10-20mA intermittently, or a wireless keyboard operating at similar current — a single Max AAA can deliver months of service. Higher-drain devices like battery-powered radios or electronic toys will exhaust the cell faster, but the alkaline chemistry handles short bursts of higher current better than cheaper carbon-zinc alternatives.

Frequently Asked

What devices are these suited to?

Remote controls, wireless keyboards and mice, wall clocks, smoke alarms, LED torches, children's battery-operated toys, bathroom scales, and other household devices specifying AAA batteries. They handle both continuous low-drain loads and intermittent moderate-drain use.

How long do they last in storage?

Energizer rates the Max AAA with a 10-year shelf life from the manufacture date printed on each cell. Store in a cool, dry place away from metal objects to maintain full capacity.

Are they rechargeable?

No. These are single-use alkaline cells and must not be placed in a battery charger. For rechargeable AAA batteries, see Energizer Recharge or similar NiMH options.

What's the voltage?

Each cell delivers 1.5V nominal voltage when fresh, declining gradually as the cell discharges. Most devices tolerate operation down to 0.9-1.0V before performance degrades noticeably.
