"394A" would be an alkaline battery **Q: is this battery advisable for Swatch Swiss with specs: 6.8x2.6, 1.55 v? Thank you** A: Yes..!! **Q: Alkaline batteries?** A: I don’t if it’s alkaline. I just replaced my original watch battery with a new identical one. **Q: Has anyone used this for a camera? my old pentax calls for a varta 394, so i'm assuming this will work, but wanted to ask.** A: "394" is the same kind of identifier as "AAA" or "18650" so it'll work as a replacement for a Varta 394. But I'm wondering what an old camera needs with such a small battery? ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect cure for my watch! *by on Reviewed in the United States June 3, 2026* Works great, quality replacement oem, nice price, received order quickly! ### ⭐⭐⭐⭐⭐ Time for a new battery *by on Reviewed in the United States May 24, 2026* Works awesome as described.
