- Wrist Watch;
- miniature alarms;
- devices for backlighting;
- Kids toys;

Such a wide range of applications is due to excellent technical characteristics. First of all, we are talking about the duration of the work. Also, do not forget about good performance at low temperatures, which many batteries cannot boast of.
Analogs of the Renata 394 battery
Sometimes a situation may occur that such a battery is simply not available in the store. In this case, you can choose an analog from another manufacturer.
Batteries with the following markings have the same dimensions and characteristics:
- 394;
- AG9;
- V394;
- R394;
- RW33;
- SR45;
- SB-A4;
- SR936SW.
The first thing to look at is the form factor. The battery must be suitable in size. Capacity is not important, the higher it is, the longer the device will work. You also need to consider the voltage that your device is designed for. More voltage can burn the device, while less can not have enough power.
Is it possible to charge the battery 394
No batteries can be charged. Only batteries can be charged, but the 394 is not.
When you try to charge, depressurization of the case, fire or even explosion may occur.

You always need to look at the voltage and dimensions, they must match Renata 394.
What to look for when purchasing
Choosing an analogue, it is worth looking at the main characteristics. Their designation can be seen on the case. Then you can guaranteedly get the right option.
When buying a battery, be sure to consider the expiration date. All silver oxide-based batteries have a limited shelf life. For Renata 394, the production date is indicated on the rib in the year-month format. If you see the inscription 18.06, it means that the product was manufactured in June 2018. It can be stored from 2 to 4 years.
It is impossible to determine the quality of the battery and its possible service life. This type of battery does not have a direct relationship between capacity and voltage. Therefore, ordinary tests do not work here.
