Description

The Eveready 9V Alkaline Gold Battery is a single 9V alkaline cell designed for low to mid-drain household devices including smoke alarms, carbon monoxide detectors, radios, wireless doorbells, guitar pedals and remote controls. The alkaline chemistry delivers 9V nominal voltage with stable output over the discharge cycle, suited to devices that draw moderate current intermittently rather than high continuous loads.

Most commonly used in mains-powered smoke alarms and CO detectors as backup power, the 9V format also powers portable radios, active guitar effects pedals, multimeters, garage door openers and older wireless microphones. The snap-on terminal design allows tool-free installation in battery compartments with spring contacts or clip connectors. At 50g the battery adds minimal weight to handheld devices.

The Eveready Gold range uses alkaline manganese dioxide chemistry, which stores more energy per gram than zinc-carbon cells and maintains higher voltage under moderate loads. Shelf life is typically 5-7 years when stored at room temperature, making the battery suitable for emergency devices that sit unused for extended periods. The single-pack format is practical for replacing individual smoke alarm batteries during annual testing without opening multi-packs.

Frequently Asked

How long does this battery last in a smoke alarm?

In a typical mains-powered smoke alarm used as backup power, an alkaline 9V lasts 12-18 months depending on the alarm model and test frequency. Battery-only smoke alarms drain faster and may need replacement every 6-12 months. Annual replacement is recommended regardless of remaining charge.

Can this be used in high-drain devices?

The Gold range is optimised for low to mid-drain devices. High-drain applications like active guitar pedals with digital effects, wireless transmitters running continuously, or motorised toys may deplete the battery quickly. For sustained high-current loads, rechargeable lithium or NiMH 9V cells typically perform better.

What's the difference between alkaline and zinc-carbon 9V batteries?

Alkaline batteries store more energy and maintain higher voltage under load compared to zinc-carbon. For the same device, an alkaline 9V will last 3-5 times longer than a zinc-carbon equivalent, making alkaline the preferred choice for smoke alarms and any device where replacing the battery is inconvenient.

Is the battery rechargeable?

No. This is a single-use alkaline cell and must not be placed in a charger designed for rechargeable batteries. Attempting to recharge alkaline cells can cause leakage or rupture.
