Capacity 50-60 mA / s, voltage 1.55 Volts, size 2.7 millimeters and diameter 9.5 millimeters, round shape.
Equipped with a silver and zinc battery. Unlike manganese and zinc batteries, it has:
- large stable voltage;
- long service life;
- reliable and durable housing.
Also suitable for devices with intermittent peak loads. It can serve as a source of electric energy in quartz and electronic watches with backlight and alarm clock.
The battery marked 399 is intended for appliances that need to be provided with constant low power. The claimed capacitive ~ 55 mAh, self-discharge is not at all large, up to about 2% per year.
Battery Applications
The battery is used in watch movements. It can also be found in computer accessories, photographic equipment, calculators, small electrical appliances with a low degree of electricity consumption.
It is also found in musical children's toys, key chains and flashlights, small medical devices. You can see it in mechanisms equipped with LED and RFID technologies. In general, the battery is used where high-quality and stable power is required.
Battery analogs 399
Replace the battery with the following equivalents:
They have similar specifications and applications. The difference is in a longer or shorter working time, parameters.
Can I charge the 399 battery
Batteries cannot be charged. Despite the fact that it is widely believed in society that some of them can be charged, since they "come to life", it is better not to experiment with this. When you try to charge the battery, it may leak, catch fire, or even explode.
Popular manufacturers and their features
The following foreign manufacturers manufacture the 399 battery:
- Renata;
- Maxell
- Citizen
- Duracell
- Varta;
- Panasonic
- Sony
- Toshiba;
- Energizer
- Eveready.
A slight difference between the produced batteries from each other in technical parameters, price and quality. It’s impossible to say exactly which device manufacturer is better. However, when buying, you need to look at the scope and select the batteries strictly for specific devices. The best way to do this is to study the information on an old battery.
Important! On the packaging itself, manufacturers display icons with devices in which it is better to use their analogue batteries.
According to user ratings, Varta, Minamoto, Sony, Renata and Maxell have the best value for money. Domestic brands have good models, which almost do not differ in parameters from foreign ones - Cosmos and Trophy.
When choosing batteries, you also need to look at the nominal capacity (the larger the longer the device will function), the voltage with power and voltage (at least 1.55 volts), the operating temperature range (choose depending on whether the device is at home or outdoors), coating material (it is better to take a corrosion-resistant coating), shelf life and storage.
