For the first time, miniature batteries were invented for electronic watches: very compact energy sources were required here. Today, watch batteries are available with different characteristics and are widely used in other electronic devices.

SR626SW Battery Specifications
The main differences between miniature galvanic batteries are their size and voltage level. The battery type SR626SW is designed for devices with low uniform energy consumption and gives a voltage of 1.55 V. The shape of this tablet is 2.6 mm high and 6.8 mm in diameter. two metals in its composition: silver and zinc, which allows it to have a voltage of 1.55 V.
Due to the physicochemical properties, silver-zinc batteries are better at lower temperatures than saline batteries. They also have a number of advantages over manganese-zinc batteries: they have a more powerful voltage, which is maintained until complete discharge, low internal resistance. Source of power
Analogs of battery SR626SW
The International Electrical Commission (IEC) has standardized power supply requirements, so consumers can now replace one brand of battery with another.
If previously used a miniature battery SR626SW from Panasonic, Maxell, Sony or Toshiba, then it can easily be replaced by Varta 377, Duracell D377, Timex BA, Bulova 606, GP 377, Renata 377. Seiko, Energizer 377, Ray-O-Vac 377, Philips 377, Lr626 and AG4.
Battery Applications
Due to its small size, watch batteries are indispensable in compact devices. They are used in watches, calculators, children's toys, headlamps, remote keys, video cameras, car alarms, remote control panels for keys, medical devices (for example, in a glucometer), computer equipment (for example, in a backup battery), etc. .d.
Due to the high cost of materials, silver-zinc batteries of a different standard size are not available and can power devices for which 1.5 V is sufficient.
Can the SR626SW be charged
The SR626SW miniature batteries operate through internal chemical processes that are irreversible. That is, a discharged battery cannot restore its charge, unlike batteries. The latter can be recharged for reuse, while these batteries must be disposed of.
Attempting to charge the SR626SW battery may result in a fire or explosion, rendering the charger unusable.
Popular manufacturers and their features
The market leader in this segment is Sony. This manufacturer is distinguished by an environmentally friendly production method: silver oxide is used instead of mercury. This does not affect quality, but provides safer storage.
The use of high quality antioxidants allows for greater capacity. The leading manufacturers of the SR626SW also include Sony, Panasonic, Maxell and Toshiba.
What to look for when purchasing
To understand which battery is suitable for a particular device, you need to understand the basic marking indicators. For ease of reading, they are unified and applied to the "pill" itself.
The first indicator that you should pay attention to is the chemical composition. The voltage level directly depends on it. Silver-zinc elements are marked SR.
Inside their class, “pills” also differ in magnitude of voltage. For devices with low and stable power consumption type LD is suitable.If the device consumes a lot of power and is uneven, you need to look for a power source with an HD characteristic. The universal battery has an MD indicator - it is suitable for all power consumption modes. The SR626SW has an LD characteristic.
Also, when choosing, you need to take into account the indicators of diameter and thickness. Often this information can be found on the packaging. If the manufacturer did not specify it, you need to measure the battery that was used previously.
On average, a “clock battery” lasts from 2 to 7 years. The discharge rate directly depends on the capacity of the battery, as well as the device that consumes the energy of the battery.
It is important to understand that from the moment the battery is manufactured, the process of “self-discharge” is started. Therefore, a battery with a closer release date will lose less charge capacity by the time it is used.
