SR41 is a silver‑oxide button cell. When you’re looking for the same size, you’ll often see multiple codes that mean the same thing on packaging.

• Silver‑oxide (same chemistry): 392, 384, SR41, SR41SW, SR41W, SR736
• Alkaline (same size): LR41, AG3, 192, L736, CX41

Matching size is important, but matching the chemistry your device calls for can help with consistent performance. Many watches and precision devices specify silver‑oxide (392/384/SR41), while some small electronics list alkaline (LR41/AG3). Check your device manual or the code on your old battery, and use the same family when possible. Package cross‑reference charts can also make it easier to confirm a compatible match.

They’re the same size button cell but use different chemistries.

• SR41: Silver‑oxide, typically labeled 392/384/SR41/SR41SW/SR41W/SR736. Often chosen for devices that benefit from a steady voltage over time.
• LR41: Alkaline, often labeled LR41/AG3/192/L736/CX41. Common for many small electronics.

Because the chemistries differ, your device may recommend one over the other. Check the original battery code or the device manual and match it. While some devices might operate with either type, results can vary by device design. If your previous battery was 392/384 (silver‑oxide), staying within that family is generally advisable; if it was LR41/AG3 (alkaline), stick with that type.

LR41 is an alkaline button cell used in many small devices. You’ll often see it cross‑listed with other codes that indicate the same size.

• Alkaline size equivalents: LR41, AG3, 192, L736, CX41
• Silver‑oxide size counterparts: 392, 384, SR41, SR41SW, SR41W, SR736

If your device or old battery specifically calls for LR41/AG3, choose alkaline. If it specifies 392/384/SR41, choose silver‑oxide. Most product pages and packaging include cross‑reference charts listing several of these codes, which can help you quickly find a compatible match. When in doubt, compare the code on your original battery or consult your device manual before purchasing.

Brands print different codes for the same SR41 size, so cross‑reference charts are helpful. For the SR41 silver‑oxide version, look for:

• Common SR41 codes: 392, 384, SR41, SR41SW, SR41W, SR736

You’ll also see the alkaline size equivalents listed on some packaging for reference:

• Same size (alkaline): LR41, AG3, 192, L736, CX41

Match both the size and the chemistry your device specifies. Precision devices often list 392/384 (silver‑oxide), while others may list LR41/AG3 (alkaline). Check the code on your old battery or the device manual, then use the cross‑reference on the product page or packaging to pick the right pack.

A quick check of your current battery or manual usually tells you what to buy. Here’s a simple approach:

1. Read the old code: If it shows 392/384/SR41, choose silver‑oxide. If it shows LR41/AG3/192/L736, choose alkaline.
2. Match chemistry: Staying with the listed chemistry can help maintain expected performance.
3. Confirm fit: The size is the same across these codes, but polarity and battery compartment design vary. Install per your device’s markings.
4. Plan quantity: If you replace these often, multi‑packs can be convenient; store spares in a cool, dry place.

When codes aren’t visible, check the device manual or product page details to align size and chemistry before purchasing.
