Amazon Basics Batteries: Choose the Right Type for Your Devices

Amazon Basics offers everyday batteries in alkaline, rechargeable NiMH, and select lithium formats across popular sizes (AA, AAA, C, D, 9V, and specialty cells like CR123A and coin cells). They’re a cost-conscious pick for remotes, toys, flashlights, small electronics, and backup kits.

Battery Types and When to Use Them

Alkaline (AA, AAA, C, D, 9V)

• Use if: The device is low to moderate drain and used intermittently (TV remotes, wall clocks, radios, basic flashlights, toys).
• Avoid if: You need frequent power for high-drain devices (gaming controllers used daily, high-output flashlights) or operation in very cold weather.
• Notes: 1.5V cells; shelf life up to 10 years when stored cool and dry.

Rechargeable NiMH (AA, AAA)

• Use if: The device is used often (wireless mice/keyboards, game controllers, flash triggers, toys) and you want lower long-term cost and less waste.
• Avoid if: The device requires 1.5V strictly or sits unused for very long periods (some sensors, certain medical or safety devices). Always check the manual.
• Notes: 1.2V nominal; best with a smart charger; many models hold charge well in storage (low self-discharge).

Lithium Primary (e.g., CR123A, CR2032)

• Use if: You need reliable performance in cold/heat or in high-drain bursts (camera flashes, tactical/EDC lights, motion sensors, some smart-home gear).
• Avoid if: Your device specifies alkaline only, or you need rechargeable capability (CR123A primaries are not rechargeable).
• Notes: Typically wide temperature tolerance; long shelf life; check your device for the exact cell type.

Choosing the Right Battery for Your Device

• Match size and chemistry: Follow the device label/manual for AA vs AAA, 9V, or specialty cells; do not substitute chemistries unless approved.
• Voltage matters: Some devices expect 1.5V (alkaline). NiMH rechargeables are 1.2V and work well in many—but not all—products.
• Duty cycle: Frequent use favors NiMH; occasional use favors alkaline; cold-weather or critical sensors often favor lithium.

Real-World Runtime Examples

Actual life varies by device, settings, and temperature, but these ballparks can help:

• TV remote (AA alkaline): 6–24 months.
• Wall clock (AA alkaline): 1–2 years.
• Game controller (2×AA): 20–40 hours on alkaline; similar or slightly less on NiMH per charge, but rechargeable for hundreds of cycles.
• LED flashlight 200–500 lm (AA): 2–8 hours on alkaline; 3–10 hours on quality NiMH depending on output level.
• Outdoor sensors (CR123A lithium): Often 6–18 months depending on activity and weather.

Storage, Handling, and Safety

• Store in a cool, dry place; keep in original packaging or a case. Avoid heat and direct sun.
• Do not mix old and new batteries, brands, or chemistries in the same device.
• Insert with correct polarity. Remove batteries from devices stored long-term.
• Never charge non-rechargeable cells. Use a smart charger designed for NiMH.
• For smoke alarms and life-safety devices, follow the device manufacturer’s battery recommendations; avoid rechargeables unless explicitly approved.
• Keep coin cells away from children; ingestion is a medical emergency.
• Recycle where available; tape terminals of 9V/coin/lithium cells before disposal to reduce short-circuit risk.

Cost-Saving Tips

• Buy AA/AAA in bulk if your household uses many devices.
• Use NiMH rechargeables for daily-use gear; keep a charged spare set ready.
• Rotate stock: mark purchase date and use older alkaline packs first.
• Choose lithium for devices in cold garages, mailboxes, or outdoor cams to avoid frequent replacements.

Compatibility Notes

• NiMH batteries work best with a charger that offers individual slot monitoring and automatic shutoff.
• Some photo gear and smart sensors specify CR123A or specific coin cells—use exactly what the manual lists.

FAQ

Are Amazon Basics alkaline batteries leak-resistant?

They are designed with leak-resistant construction and perform best when stored properly and removed from devices that sit unused for long periods. Replace aging cells promptly.

Can I use NiMH rechargeables everywhere I use alkaline?

Often, yes—especially in high-drain or frequently used devices. Some products expect 1.5V alkaline and may not perform as intended on 1.2V NiMH. Check the device manual.

What is the shelf life?

Amazon Basics alkaline batteries list up to a 10-year shelf life when stored in a cool, dry place. Lithium primaries also store well long-term. Rechargeables should be topped off every few months.

Are CR123A batteries rechargeable?

No—CR123A primary cells are not rechargeable. Use only if your device specifies them, and never attempt to charge them.

Which batteries are best for cold weather?

Lithium primary cells (such as CR123A) maintain performance better in low temperatures than alkaline or NiMH.
