For small devices running on electric current, miniature batteries are available. Such products have a large internal resistance, which contributes to a long and safe delivery of the required amount of electricity. In order for such a battery to occupy a minimum of usable area, it is made in the form of a flat rounded battery. One of the typical representatives of this class of batteries is the Renata 321 battery.

Can I charge the 321 battery
The 321 silver-zinc battery is not a battery - this means that after a complete discharge it will not be possible to restore it. To resort to various tips on "resuscitation" of elements of this type, which can be found on the Internet, is also not recommended because of a possible explosion or fire of the product.
This battery has a very low rate of self-discharge, so in order to exclude the possibility of a sudden cessation of operation of an important device, it is enough to purchase a new element as a spare product.
Popular manufacturers and their features
In order to protect yourself from the purchase of low-quality products, it is recommended to pay attention to the batteries of the following companies when buying a new battery:
- Energizer - An American manufacturer of high-quality chemical sources of electricity. The products of this company are distinguished by the fact that the most advanced technologies are used in the manufacture of products. This means that the battery will last much longer, with standard values for the shape and size of the battery.
- Varta - When purchasing products from this manufacturer, you can always count on European quality.All parameters of such products fully comply with the reference indicators, while the discharge of the product occurs very evenly, ensuring the maximum duration of electronic devices.
- Camelion - batteries based on silver oxide from a well-known Chinese brand are distinguished by high power and a long period of return of electric energy without reducing the voltage.
- Maxell - The 321 watch battery of this manufacturer is characterized by a long and uniform discharge of electricity. The product also has a high-quality housing that can easily endure adverse operating conditions.
- Trophy - A domestic manufacturer of quality electronic products. The 321 battery of this brand is not inferior in its parameters to the best foreign samples.
In addition to the listed manufacturers, when choosing a 321 battery, you should pay attention to products under the brands: Rexant, Videx, Vinnic.
What to look for when purchasing
When buying a 321 watch battery, you should pay attention to the following features:
- Matching Type.
- No mechanical damage.
- The shelf life of the product should not come to an end.
Most of the necessary information is applied to the body of the product. On a metal surface, as a rule, there is a designation of the type of battery, voltage and manufacturer. An additional marking is applied on the packaging, which indicates the expiration date of the product and its capacity.
