1.5V is the battery’s nominal voltage — the electrical pressure it can provide — not its physical size. You’ll see 1.5V across several battery formats found on this page.

• Common 1.5V sizes: AA (LR6), AAA (LR03), C (LR14), D (LR20), N (LR1), AAAA (LR8D425), and button/coin cells like LR44/AG13. Some silver‑oxide buttons (e.g., 303/357) are also around 1.5V.
• Match what your device needs: Devices are designed for a specific size and chemistry, so check the battery compartment or user manual.
• Shopping tip: On Walmart.com, you can filter by battery size and see voltage and chemistry in the product details to find a proper match.

AA is a physical size, while 1.5V is a voltage. Many AA batteries are 1.5V, but 1.5V also appears in other sizes.

• Size vs. voltage: If your device calls for AA (often marked “AA” or “LR6”), stick with that size, even though other 1.5V cells exist (AAA, C, D, N, AAAA, button cells).
• Chemistry differences: AA batteries come in different chemistries (such as alkaline, lithium, or rechargeable). Some rechargeables are 1.2V, while some newer rechargeables list 1.5V. Check your device guidance.
• Shopping tip: Use size filters on Walmart.com to narrow to AA and review the Specifications section for voltage and chemistry before buying.

C batteries refer to a size (often labeled “C” or “LR14”), and many of them have a 1.5V nominal voltage. That said, size and voltage serve different purposes.

• Compatibility: Even if voltages match, a C cell will not fit where another size (like AA) is required. Always install the size specified by your device.
• Capacity context: C cells are physically larger than AA/AAA and typically offer more capacity, which can be useful for higher‑drain or longer‑running devices.
• How to confirm: Check your device’s battery compartment for “C”/“LR14” markings and review product pages on Walmart.com for both size and voltage.

1.5V batteries come in different shapes because 1.5V is the voltage, not the size.

• Cylindrical cells: AA, AAA, C, D, N, and AAAA are tube‑shaped with a raised positive tip and a flat negative end. Their length and thickness vary by size.
• Button/coin cells: Small, flat discs (e.g., LR44/AG13, 303/357). Codes are typically printed on the top surface.
• Labeling to look for: Most wrappers or packaging list the size code (AA/LR6, AAA/LR03, etc.) and “1.5V.”
• Shopping help: Product images and the Specifications section on Walmart.com can help you confirm shape, size code, and voltage before purchase.

Good storage and disposal habits can support performance and safety.

• Storage: Keep batteries in a cool, dry place, ideally in original packaging or a case to prevent terminals from touching. Avoid extreme temperatures and remove batteries from devices you won’t use for a while.
• Handling: Don’t carry loose cells with metal objects. For button/coin cells, consider covering the terminals with non‑conductive tape if storing or transporting for recycling.
• Recycling/disposal: Follow local rules. Some areas accept household batteries at recycling drop‑offs; others allow disposal in household trash. Never incinerate.
• Tip: Check your community’s guidance, and review chemistry details on Walmart.com product pages to align with local disposal recommendations.
