Batteries are distinguished by type of use, composition and size. For each device, some specific batteries are suitable. In this article, we will talk about the characteristics and analogues of the LR754 battery, which is popularly known as the “clock battery”.

LR754 Battery Specifications
LR754 is a manganese alkaline battery. It has a rounded flattened shape. It is smaller in size than CR2032. Her body is the positive electrode, and the site is the negative, which is located on one of the ends. The negative electrode is always smaller than the battery area.
Attention! Due to the small size of the battery, the LR 754 can be easily swallowed by children. Once in the body, it will cause severe poisoning. Therefore, it is recommended that these items be stored out of the reach of children.
These batteries have high internal resistance. LR754 specifications are as follows:
| Parameter | Value |
|---|---|
| Basic designation | LR754 |
| View | Manganese-alkaline |
| The form | Tablet (Coin) |
| Capacity | 50 mA / h |
| Voltage | 1.5 V |

| Diameter | 7.9 mm |
| Height | 5,4 mm |
| Working temperature | from -30 to + 50˚C |
| Weight | 1,5 gr |
This battery according to the standard of the international electrotechnical commission is marked LR48.
Battery Applications
LR754 is used in devices with medium or low power consumption. These include:
- flashlights;
- laser pointers;
- Kids toys;
- clock;
- remote controls for audio systems;
- calculators.
Due to the fact that the LR 754 can withstand strong low temperatures, devices with which you have to work outdoors in the cold season will not fail at the wrong time.
Battery Analogs LR754
LR754 can be replaced with the following equivalents:
- G5;
- 393;
- 193;
- AG5;
- 393A;
- LR48;
- SR754;
- CX193;
- SR754SW.
In terms of sizes, they are no different from the original power source. The voltage, voltage and power have the same characteristics. Only the designation is changed.
Can I charge the LR754 battery
Manganese-alkaline batteries are non-rechargeable batteries. But battery owners do not need to worry about this, as batteries are slowly consuming power and cost quite a bit.
If you try to charge with a conventional battery charger, there is a risk of fire or short circuit.
Popular manufacturers and their features
Popular manufacturers of LR754 are:
- GP.
- Varta;
- Seiko;
- Renata;
- Camelion
Manufacturers carefully adhere to standards for the manufacture of batteries. Batteries can operate at temperatures from minus 30 degrees Celsius to forty with a plus sign. Storage is allowed with a temperature difference of not more than forty degrees with a minus sign in Celsius and up to plus 50.
During storage, the LR754 may not lose discharge for a long time. And the same standard sizes will fit any equipment that uses batteries with this marking.
What to look for when purchasing
When buying batteries, you need to pay attention to the company that released them. If the name is unknown to the buyer, then you should refuse to purchase. Because the standards may not be observed, and this will cause not only malfunctions in the equipment during operation, but can lead to failure of the device itself.
Size matters. If the buyer does not remember the name of the battery, then experts do not recommend buying “for memory”. If the battery is smaller or larger than the platform for it, the device will not work.
It is not recommended to use batteries with different chemical systems in the same device, even if they are suitable in size. This will cause the device to fail.
Batteries should not lie in the sun. And the battery brought from the cold must be warm for at least 3 hours before it is used by mono.
