Silver-zinc batteries of size SR44 are in great demand today. The main advantage of air-zinc, manganese-zinc or oxide-mercury counterparts is a higher voltage and stability of internal resistance.

SR44 Battery Specifications
SR44 batteries are made on a silver-zinc basis. Outwardly, it is not much different from similar “coins and tablets” in shape, made on the basis of other chemical elements. In appearance, these are the same small cylinders whose height is much smaller than the diameter.
SR44 batteries have the following key features:
- diameter - 11.6 mm
- height - 5.4 mm;
- voltage - 1.55 volts;
- capacity - up to 200 mAh;
- self-discharge level - low;
- weight - 2.09 g;
- temperature operation from minus 10 ° С to plus 55 ° С;
These batteries have anti-vibration and shockproof properties.

Battery Applications
Manufacturers indicating the characteristics of the galvanic cell are marked HD - this means that the battery is able to commission electrical appliances with uneven high power consumption.
These include:
- calculators;
- weather stations;
- musical toys;
- multifunctional watches;
- remote controls;
- medical electronic equipment;
- car key rings, etc.
The devices will work properly until the battery is discharged, and the battery keeps a constant voltage until it completely dies.
Analogs of battery SR44
Replacing a dead battery with a new one is not always possible to find exactly the same. In this case, you can pick up an analog with a different marking, as many manufacturers have it different.
The SR44 battery can be replaced with the following equivalents:
The fact is that many well-known brands produce exactly the same galvanic products, but under different markings. For example, to select an analog battery SR44 you can use the following options:
Can the SR44 battery be charged
Understanding how high and unique the operational characteristics of such batteries are, many people wonder, is it possible to charge them after they go down?
The fact is that batteries suitable for additional recharging are called batteries, and all batteries initially do not provide such a function. In no case can completely charge fully sealed “discs”.
Popular manufacturers and their features
Many manufacturers make SR44 batteries. The most popular brands are: Renata, Energizer, Rayovac, Cosmos, Varta, Maxell, Duracell, Panasonic and Sony ,.
Many other manufacturers produce products no worse than quality, but these brands are considered the most popular.
What to look for when purchasing
When buying a silver-zinc battery SR44, you need to pay attention to the following points:
- Dimensions Must be 11.6 × 5.4 mm, a difference of ~ 0.1 mm is allowed;
- Voltage. Some manufacturers have 1.55v for 1.5v, so first you need to make sure that this is enough for your device .;
- Capacity. The more, the longer it will work;
- Release date. It should be as fresh as possible, since the batteries have a self-discharge;
- Packaging. a well-packaged product reduces the likelihood of buying a fake;
And of course - the price, the manufacturer - a good battery cannot be cheap.
