Amazon Basics 9V Alkaline Batteries

Amazon Basics 9V Alkaline Batteries

9V alkaline batteries suited for home safety devices and everyday electronics. Use them in smoke and carbon monoxide alarms, multimeters, portable radios, and many audio accessories where consistent power and easy replacements matter.

When to Choose These

• Smoke and CO alarms that specify 9V cells and require annual replacements
• Test equipment (multimeters, meters) used intermittently
• Audio gear such as wireless mic bodypacks or guitar pedals for short sessions
• Emergency kits where long shelf storage and ready-to-use power are important

When to Consider Alternatives

• High-drain, frequent-use devices: consider lithium 9V for longer runtime
• Cost-sensitive frequent use: consider rechargeable NiMH 9V (if the device supports them)
• Cold environments: lithium 9V performs better in low temperatures
• Devices specifying a different chemistry or size: follow the device manual

Typical Runtime Estimates

Actual runtime varies with device current draw, temperature, and device cut-off voltage. Use these as planning ranges:

Buying and Pack Guidance

• Small packs (1–2): quick household replacements
• Value packs (4–8): multiple devices across a home or office
• Bulk (12–48+): facilities, schools, A/V teams, and maintenance programs
• Check the date code; rotate stock first-in, first-out for best results

Storage and Handling

• Store in a cool, dry place; avoid heat and humidity
• Keep in original packaging or a case to prevent terminals from touching
• Do not mix old and new batteries or different chemistries in a device
• Remove batteries from devices not used for extended periods
• Recycle or dispose of according to local regulations

Compatibility Notes

• Also labeled as 6LR61 or 1604 alkaline
• Fits standard snap-style 9V battery connectors
• Not rechargeable—do not attempt to charge alkaline batteries
• Always follow your device manual for battery type and replacement steps

FAQ

• How long will these last in a smoke alarm?

  Plan for about 6–12 months, but replace sooner if you hear a low-battery chirp or per the alarm manufacturer’s schedule.

• Are these rechargeable?

  No. These are single-use alkaline batteries. Use NiMH 9V rechargeables only in devices that support them.

• What is the shelf life?

  Alkaline 9V batteries typically keep their charge for several years when stored properly. Check the package date code and aim to use within about 5 years for best performance.

• Will these work in wireless microphones?

  Yes. Expect roughly 4–10 hours depending on the transmitter and settings. For long events or cold venues, consider lithium 9V.

• Do these replace 6LR61/1604 batteries?

  Yes. Those are common designations for standard 9V alkaline size.
