The silver-zinc tablet-shaped battery is designed for devices with uniform low or medium power consumption. Most often, it is chosen for watches.
They have a minimum cost, even when it comes to batteries from advertised and well-known world brands. From the article you will learn about the technical features of the models of various companies, analogues that can be replaced with them, and what parameters matter when choosing and buying.

377 Battery Specifications
When choosing a power source, it is worth paying attention not only to the manufacturer. In order for the batteries to last for a long time, it is not necessary to buy an expensive one. The main thing is that it would be suitable for technical parameters. Devices 377 are available in a single format, that is, their sizes are the same.
In particular:
- diameter is 6.8 millimeters;
- thickness is 2.6 millimeters.
Power supplies in appearance resemble a small coin. The shape is slightly flattened, since the thickness is several times larger than the diameter. They are silver-zinc in type.
Such batteries do not deteriorate for a long time, their term is about 5 years. Capacity 26 mAh and voltage of 1.55 Volts. That is, they need to be used in small devices with a low level of consumption.

Battery Applications
The main field of application of a low-voltage power supply is a watch. Energy is enough to provide functionality for several years (good batteries are used for five years or longer).
Batteries of this type are also used for miniature devices. In everyday life you do not often meet them. These are mainly specific devices, such as sensors.
Analogs of the battery 377
Analogues of a coin-shaped battery are many other options. They have other digital characteristics, but the same size. Popular replacements are the SR66, SR626SW, SB-AW, Lr626, RW329.
They have the same capacitance, size and voltage. Although the service life may vary depending on the type and technology used.
Can I charge the 377 battery
Type 377 power source is not a battery, therefore it is not charging. Although this is not a problem, the alkaline battery lasts a very long time. Moreover, it has a low cost.
Separate attention should be paid at the time of disposal after use. You can’t throw them away, it will be optimal to take the used batteries in your city to the collection point.
Important! The danger is that young children can swallow it. Silver-zinc element can cause severe poisoning.
Popular manufacturers and their features
Renata, Duracell and Vaxell models show high efficiency in terms of performance and voltage. Products are not very expensive, now they can be bought at a price of 40 rubles. They serve, according to user reviews, about 15-20 percent longer than others. But you should pay attention to watch batteries from such companies as Camelion, Renata 377, Varta, Energizer, Minamoto, GP and Sony.
They are also quite productive. A watch battery produced by a Russian manufacturer, as a rule, costs the least, but has average statistical characteristics.
What to look for when purchasing
The battery that is selected for the hand watch must be suitable in size.Even a millimeter wobble will not allow the battery to be installed. If the buyer does not know the exact dimensions, then they can be viewed on the previous battery or measured. Also, information on which power supply is suitable can be found in the technical passport of the device itself.
Also, attention should be paid to:
- voltage and power of work;
- capacitance and voltage;
- operation parameters (including the designation of the range of operating temperatures, humidity, and the like);
- the presence of a special holder in the kit (if necessary);
- power supply coating.
A good 377 battery lasts five years. Reliable manufacturers give a guarantee on a product. In case of detection of problems or production defects, the model purchased from them can be exchanged for another or the money spent on it returned.

from 5 years serve?
what is it that needs to be nourished so that it serves so much! 
I have some batteries in a year covered with oxides,: evil: but still the same Varta, Energizer, GP
This is in a gentle mode, well, there in the device, which is used once every half a year)
My watch worked 2 years 7 months.
Casio watches bought for 3500 rub.
While I put the usual battery, time will tell how long it takes.
