9V alkaline four-pack for safety devices

This pack supplies four 9 V alkaline cells rated at 500 mAh each. They are intended for smoke detectors, fire alarms, carbon-monoxide detectors and professional audio equipment such as guitar pedals. The chemistry delivers steady voltage for mission-critical household electronics.

Alkaline chemistry and single-use limitation

As primary alkaline cells they cannot be recharged; once depleted they must be replaced. The 500 mAh capacity defines the total charge available, so runtime depends entirely on the current draw of the device. Leakproof construction protects equipment from corrosive damage during extended service.

Check device voltage and compartment fit

Verify that each device requires a 9 V supply and accepts the standard 6LR61 form factor before ordering. Confirm the battery compartment can accommodate four cells if you plan to power multiple units simultaneously. The 7-year shelf life supports bulk storage for emergency readiness.

Questions about this item

Is the 4-count pack the only size available for these 9V alkaline batteries?

The supplier lists this model in a 4-count pack. Other Voniko 9V packs come in 2, 12, 24 and 48 counts.

How long will a 500 mAh 9V cell typically run a smoke detector?

A 500 mAh alkaline 9V battery usually powers a residential smoke detector for about one year before the low-battery chirp begins.

What does the 6LR61 designation tell me about the battery interface?

6LR61 is the IEC code for a standard 9V alkaline cell with snap terminals, so it fits any device built for a 9V battery.
