"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 ### ⭐⭐⭐⭐⭐ Review *by D***9 on 19 January 2026* a reliable battery for watches, never any fail out of package , very accurate voltage , good price ### ⭐⭐⭐⭐⭐ Review *by P***K on 12 February 2026* Revived my old Tag Heuer which had a previous battery change at some watch guy that did not work.
