LR44 battery specifications
LR44 Dimensions:
The diameter is about 11.6 mm and the thickness is about 5.4 mm.
LR44 Electrical Specifications:
Capacity: Generally around 150mAh-200mAh.
Internal resistance: generally between tens of milliohms and more than 100 milliohms. Lower internal resistance helps reduce energy loss during battery discharge and improve battery performance and efficiency.
Discharge characteristics: Under normal use, LR44 batteries can provide a relatively stable voltage output. During the discharge process, the voltage will gradually decrease. When the voltage drops to a certain level, the battery can no longer meet the normal working requirements of the equipment and needs to be replaced.
Nominal voltage: 1.5V.
LR44 Other specifications:
Weight: Approx. 2.5 g.
Packaging: Usually sold in bulk or card form. Common packaging includes blister packaging, card packaging, etc., which are convenient for consumers to purchase and use.
LR44 battery characteristics and applications
1. Features of lr44
Small and portable: The LR44 battery has a diameter of 11.6 mm and a thickness of 5.4 mm, and is button-shaped. The small shape saves space, is conducive to lightweight and miniaturized design of the device, and is easier to carry.
Stable performance: As an alkaline manganese battery, it uses potassium hydroxide as the electrolyte, has excellent electrochemical performance, and a nominal voltage of 1.5V. During the use cycle, it can continuously output a stable voltage to ensure stable operation of the equipment and reduce the risk of equipment damage due to voltage fluctuations.
High energy storage efficiency: high energy density, can store more electrical energy in a limited space, low self-discharge rate, even if not used for a long time, the power loss is relatively slow, and can meet the power needs of the equipment.
Strong adaptability: It has good high and low temperature performance, can work normally in ambient temperatures of -20℃ to 60℃, adapt to different climatic conditions and usage scenarios, and greatly broadens its application range.
2. Application of lr44
Civilian consumption: With advantages such as small size and long battery life, it can continuously provide energy for devices such as watches, calculators, and remote controls. Under normal circumstances, one LR44 battery can keep a watch running for months or even years;
Medical and health industry: widely used in small medical equipment such as blood glucose meters, blood pressure meters, and thermometers.
Security monitoring field: widely used in various security equipment, such as wireless door magnets, window magnets, smoke alarms, etc. They require batteries to maintain long-term stable operation. LR44 batteries have long life and high stability, ensuring that security equipment is always in storage status.
Industrial and scientific research scenarios: Some industrial equipment and scientific research instruments with extremely high precision requirements need to work for a long time in complex environments. Its wide temperature adaptability and stable power supply performance meet the working needs of these devices under different working conditions.
lr44 battery equivalent
AG13 Battery: This is the direct equivalent of the LR44 battery. It is an alkaline button cell similar to the LR44, with a voltage of 1.5 volts and the same dimensions, approximately 11.6 mm in diameter and 5.4 mm thick. AG13 batteries are often used in the same devices as LR44 batteries, and the two are compatible and can be safely used interchangeably.
A76 Batteries: These two batteries have the same size and voltage characteristics and are commonly used in devices such as laser pointers, digital thermometers, and remote controls. A76 batteries are an alternative to LR44 batteries due to their availability and compatibility.
357 Battery: The 357 battery is a silver oxide battery with a different chemistry than the LR44 battery. However, it is the same size as the LR44 and has a similar voltage, providing a nominal voltage of 1.55 volts, which is slightly higher than the LR44 battery. The 357 has a higher energy density and a more stable output voltage, which is an advantage in applications with higher power requirements such as medical equipment or high-precision instruments.
There are also some other models such as L1154, 303, RW32, V303, etc., which are all silver oxide batteries, which are basically equivalent to LR44. The size and voltage are similar to LR44 batteries, and they can be replaced by each other in some equipment.
The difference between LR44 battery and 357 battery
357 batteries are silver oxide batteries, while LR44 batteries are soluble batteries. 357 batteries have advantages in service life and long-term voltage level, but they are slightly more expensive.
357 and LR44 batteries produce electricity through different materials and different chemical reactions. The silver oxide 357 battery performs better than the soluble LR44. The voltage of the 357 battery is stable at around 1.55 volts until its synthetic energy is almost exhausted, at which point the voltage drops sharply. The voltage of the soluble LR44 battery continues to drop over its discharge life.
The effective capacity of the 357 is about twice that of the LR44, although the capacity values expressed by the manufacturer in mAh may appear to be closer. Since the voltage of the LR44 drops faster, its voltage may become too low to work properly even though there is still extra electrochemical capacity.
Both 357 and LR44 batteries can be used in most applications, but for equipment that requires a steady voltage (such as precision calipers and some watches), the 357 provides a better steady voltage performance.
