Description

Energizer Alkaline Power AAA batteries deliver 1.5V output in the standard LR03 cell format, supplied here as a 12-unit pack. The alkaline chemistry provides stable voltage across discharge, making these batteries suitable for moderate-drain devices like TV remotes, wireless keyboards, wall clocks, bathroom scales and LED torches.

The 7-year shelf life allows these batteries to be stored in a drawer, car glovebox or emergency kit without degrading significantly before use. Leak-resistant construction reduces the risk of electrolyte damage to device contacts during storage, though no battery chemistry is entirely leak-proof after full discharge or prolonged shelf life beyond the rated period.

AAA (LR03) is the second most common household battery size after AA, fitting devices where a slimmer cylindrical cell is needed. The 12-pack format suits households and workplaces that use multiple AAA devices, providing a bulk quantity at lower per-unit cost than smaller packs. Each cell weighs approximately 12.5g and measures 44.5mm length by 10.5mm diameter.

Frequently Asked

How long do these batteries last in storage?

Energizer rates the Alkaline Power range at 7 years of shelf life when stored at room temperature. Actual stored capacity depends on temperature and humidity — cooler, drier storage extends shelf life, while heat accelerates self-discharge.

What devices are AAA batteries typically used in?

AAA cells fit TV remotes, wireless computer mice and keyboards, digital thermometers, bathroom scales, small LED torches, headlamps, and many portable electronics where a slimmer cell is needed compared to AA.

Are these batteries rechargeable?

No. These are single-use alkaline batteries and cannot be recharged. Attempting to recharge alkaline cells can cause leakage or rupture. For rechargeable AAA cells, look for NiMH (nickel-metal hydride) chemistry batteries instead.

What does LR03 mean?

LR03 is the IEC (International Electrotechnical Commission) designation for AAA alkaline batteries. LR indicates alkaline chemistry, and 03 is the size code. It's the same cell as what consumer packaging calls AAA.

Shipping & Returns

Free worldwide delivery

Free worldwide delivery on all orders over £99. International orders for third-party brand products may be subject to an additional courier surcharge based on volumetric weight, particularly on larger lighting fixtures — if a surcharge applies, our team will email you with the amount before dispatch and you can proceed or cancel for a full refund. See full delivery terms.

Returns

30-day returns window from delivery. As all our products are electrical or lighting goods, returned items must be inspected and recertified by a qualified electrician before resale — the cost of this inspection (25–40% of the item value) is deducted from your refund.
