Energizer's battery and portable-lighting heritage stretches back more than a century. Its predecessor business developed an early consumer dry-cell battery in 1896 and followed it with a handheld electric flashlight in 1898, linking stored power and portable illumination from the outset.

Later milestones associated with the company's history include commercial cylindrical alkaline batteries, lithium AA cells and mercury-free battery technology. These developments helped expand the uses of portable power across household, professional, medical and electronic devices.

The present range covers alkaline, primary lithium, rechargeable, coin, specialty and hearing-aid batteries alongside torches, headlamps and other portable lights. Chemistry, size, voltage, capacity, shelf life and equipment requirements should be checked carefully when selecting a replacement cell.

Power-Hub carries Energizer across battery, charger and portable-lighting categories. The live category ranking below shows the strongest areas of the current catalogue, followed by five featured products available through the store.
