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.
Review: 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.

## 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
