Review: Just works and good value Review: Las pilas (que no se entregan en caja, se entregan en un blister las 5 unidades), funcionan adecuadamente. No he podido comprobar los parámetros de duración en un uso cotidiano (las he usado para un reloj), pero los valores de voltaje son los esperados (chequeado con polímetro). Por ahora solo puedo decir que es un producto que cumple con lo esperado y a un buen precio. ## Features - manufacturer: Sony - Item Trademark: SONY - Item Weight: pounds, pounds, 0.10, 0.10 - Item Category: Battery ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002DQFFZO | | Antenna Location | Calculator, Toys, Watch | | Battery Capacity | 23 | | Battery Cell Type | Silver Oxide | | Battery Weight | 5 Grams | | Best Sellers Rank | #75,195 in Electronics ( See Top 100 in Electronics ) #1,180 in Disposable Household Batteries | | Brand | Sony | | Compatible Phone Models | Sony | | Customer Reviews | 4.4 4.4 out of 5 stars (2,933) | | Item Weight | 45 g | | Manufacturer | Sony | | Model Name | FBA_364 | | Model Number | 364 | | Number of Batteries | 5 A batteries required. | | Reusability | Single Use | | UPC | 008562012493 008562007437 | | Voltage | 1.55 Volts | ## Product Details - **Battery capacity:** 23 - **Battery cell composition:** Silver Oxide - **Brand:** Sony - **Number of batteries:** 5 A batteries required. - **Recommended uses for product:** Calculator, Toys, Watch ## Images ![Sony 364 (SR621SW) 1.55V Silver Oxide 0% Hg Mercury Free Watch Battery (5 Batteries) - Image 1](https://m.media-amazon.com/images/I/61juu-sntHL.jpg) ## Questions & Answers **Q: Is this battery silver oxide?** A: SR means Silver Oxide **Q: does this replace a 621 battery?** A: If you have an SR621 battery, Yes it does. But not a brand name designater 621. You MUST be careful with only replacing SR621 with SR621. Check your old battery first. **Q: Is the 5 pack 5 batteries or 25 batteries? It say multiple places there are 5 batteries per pack.** A: It is 5 batteries....not 5 packs of 5 ea....you can also buy a 10 pack which is just 10 batteries in the pack. Each battery has it's own blister pack and they are all attached, so you just tear each single battery pack along the dotted line to separate one at a time so the rest stay sealed. Hope that helps.... **Q: does this replace the 321 watch battery?** A: I don't think so. It would be a 364. (the 621) Sorry ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by E***S on 26 December 2019* Just works and good value ### ⭐⭐⭐⭐⭐ Review *by S***S on 8 January 2017* Las pilas (que no se entregan en caja, se entregan en un blister las 5 unidades), funcionan adecuadamente. No he podido comprobar los parámetros de duración en un uso cotidiano (las he usado para un reloj), pero los valores de voltaje son los esperados (chequeado con polímetro). Por ahora solo puedo decir que es un producto que cumple con lo esperado y a un buen precio. ### ⭐⭐⭐⭐⭐ Review *by A***Y on 11 March 2019* Replacing a battery can easily cost £7-£10. With this 5 piece pack, you can save a lot of quid. And by the way, these are the actual batteries which Fossil watch use / company fitted. The delivery was also quick and no complaints with the quality. ## Frequently Bought Together - Sony 364 (SR621SW) 1.55V Silver Oxide 0% Hg Mercury Free Watch Battery (5 Batteries) - Sony Battery 377 (SR626SW) Silver Oxide 1.55V (5 Batteries Per Pack) - Energizer Batteries 371 / 370 (SR920W SR920SW) Silver Oxide Watch Battery.
