## Questions & Answers

**Q: How long will this battery work in a watch?**
A: Not sure. Depends on the watch. They are so cheap I don't sweat it. My wife has collection of cheap "fashion" watches, so just buy various size batteries.

**Q: Can i just use the same size battery in my watch as this... I cant imagine habing 20 different battieries for watches**
A: There are many different sizes of batteries. You must use the same # associated with the battery currently in your watch. If this battery is the same #, great. If not, don't use it.

**Q: Are these the same as LR920 1.5 volt?**
A: Pretty sure they are, in fact these (SR920) are silver oxide instead of alkaline and should last longer. So yes, they will work and most likely last longer. 🙂👍

**Q: Hello, Please indicate expiration date of these batteries. Thanks.**
A: i have not ordered or received sr920sw batteries. i received sr521sw with expiration date of 06-2013. my best guess i received these batteries app. 09-2103, about 3 months past the expiration date.  i read a comment that indicated the batteries have no expiration date. my sr521sw's clearly has an exp. date of 06-2013.

### ⭐ Review
*by H***E on 12 October 2023*

Al momento de darme cuenta que mi reloj me avisaba qué tenía batería baja y abrir el paquete para sacar la segunda me doy cuenta que duró demasiado poco y al buscar la caducidad me doy cuenta que está bajo una etiqueta (convenientemente), no siendo suficiente esto alguien tachó todas las fechas de caducidad con algún plumón permanente de tal manera que ni siquiera retirando la etiqueta es posible leerla. No creo dure más de un par de meses cada batería, no volvería a comprar de este vendedor definitivamente es un engaño.
