Ⅰ.LR44 battery introduction

1. LR44 battery, also known as AG13, A76, 357 and other different types, is a kind of small alkaline battery, commonly used in various small electronic equipment, toys, notebooks, calculators, desks, remote controllers, etc.Battery Chargers

The first letter represents the battery system code, "S" represents silver alloy battery, "L" represents stainless steel battery. The second letter "R" representative cylindrical shape. The last digit representative degree, specific degree, and unification processing. LR44 middle "44" representative outer diameter 11.6mm, height 5.4mm. LR44 battery thickness is about 5.4 mm (0.21 mm).

LR44 battery is a alkaline battery, positive polarity is normal ZnOH2, negative polarity is Ag2O.

A typical LR44 battery voltage is 1.5V, with 3 single batteries connected to each other, each single voltage is 1.5V, due to which all LR44 batteries have a voltage of 3 individual voltages, 1.5V + 1.5 hits + 1.5 hits = 4.5 hits.

Pay attention to the demand, the voltage of the LR44 battery is not the same as other normal batteries (such as AA batteries or AAA batteries), so please ensure that the correct voltage is used when changing batteries.Batteries

2.Performance in low or high temperature environment with LR44 battery

LR44 battery can affect the performance in low temperature or high temperature environment, this is because temperature change affects the battery's internal chemical reaction rate.

Under low temperature environment:

Under low temperature, the battery's internal resistance is increased, and the battery's power supply capacity is lowered.

Some equipment may appear in a cold environment and performance may be degraded, such as electronic equipment may be related or may indicate a malfunction.

Under high temperature environment:

Under high temperature, more self-discharge can occur inside the battery, resulting in shorter battery life.Electronic Battery

When the battery is at high temperature, leakage or swelling may occur, and the battery may be damaged.

 

Ⅱ.357 battery introduction

1.357 battery, also known as SR44 battery, is a kind of small alkaline battery. Standard standard rating is 1.5, usually used for small electronic equipment, calculators, calculators, counters and other equipment with low current and long life.

357 battery is a alkaline battery, positive is Ag2O, negative is ZnOH2.

A typical 357 battery has a voltage of 1.5%, two batteries are connected to each other, each unit has a voltage of 1.5%. The voltage is composed of two batteries connected to each other, the voltage of each unit is 1.5 voltages, so the voltage of each 357 cells is the voltage of 2 units, which is 1.5 voltages + 1.5 voltages = 3 voltages.

2.357 battery in low temperature or high temperature environment performance

Under low temperature, the battery's internal resistance is increased, and the battery's power supply capacity is lowered.

In a high temperature environment, the chemical reaction rate of the battery increases, which can lead to the consumption of battery capacity.

Extreme low or high temperatures can affect 357 battery performance and life. For this reason, the battery used in the most suitable working temperature range, to ensure normal operation of the installation and the best performance of the battery.

 

 

Ⅲ.Silk battery

 

357 is LR44 model No. button battery, this 357 is LR44 model battery.

Because the battery is not the same model number in each country, the name is different, but the battery is the same standard. For example, LR44 model number has different names for the same product, AG13, 357A, etc. Commonly used rechargeable batteries have this kind of chemical composition: toughness, toughness, steel-silver, steel-air, steel-bicarbonate, lithium rechargeable battery, rechargeable rechargeable battery, etc.

In the positive alkaline batteries, aluminum oxide batteries, and air-powered batteries used, the chemical reaction caused by the chemical reaction caused by the components in the negative electrolyte, which causes corrosion and consumption, does not reduce the available capacity of the battery, and is possible. In-house production, the internal pressure of the closed-type battery increases and expands.

This has the effect of suppressing this, and normally there is less water than the surface of the pot, but this is also the cause of the deterioration of the battery environment. There are no batteries on the market, but because of the technology or other reasons, the no-lug batteries are not very popular.

In the absence of batteries, there is still a limit to the number of batteries that are prohibited in general, but there is still a limited number of them.

3.Separate life span

LR44: Equipment wear and tear is one of the major factors in determining battery life. Low consumption equipment, such as a small calculator, can use LR44 battery for a long time. Usage rate affects battery life. Frequent use equipment can lead to battery exhaustion.

357: High-consumable equipment can be replaced by exhaustion 357 Battery power consumption, battery life conditions also affect life. Long battery life under dry, light and temperature conditions. Temperature influences the internal chemical reaction rate of the battery. Low temperature can lead to battery capacity drop, and high temperature can lead to battery exhaustion.

 

4. Structural division

Battery composition: LR44 battery with 3 single battery connection system composition, and 357 battery with 2 battery single battery connection system composition. This is also the cause of the difference in voltage.

Application difference: Due to the difference in capacity and voltage, LR44 battery and 357 battery are usually used for different types of equipment. LR44 battery application for small low consumption equipment, and 357 battery application for low demand current and electricity  equipment.

3.Battery Recycle Box: There are a few social areas, and it is possible to leave the battery recycle box unattended. This kind of collection box is usually located in public places, Rucho cities, schools or government agencies.

4. Unnecessary waste tank: Unnecessary batteries are directly damaged in the normal tank, because the chemicals in the battery can create environmental pollution.

 

VII. LR44 and 357 battery construction principle

LR44 and 357 battery work principle is the same, the city has negative (negative) reaction and positive (positive) reaction.

Negative reaction:

In the battery, the voltage (Zn) is usually charged negatively. During the chemical reaction, the iron (Zn²⁺) emits electrons (e⁻), in the incoming battery circuit. This process can be displayed by:

Zn → Zn²⁺ + 2e⁻

Positive (positive) reaction:

Positive polarity is usually composed of silver oxide (AgOH). During the chemical reaction, the oxidized silicon is connected to the electron, and the oxidized silicon (Ag⁺) is produced on the positive side. This process can be displayed by:
AgOH + e⁻ → Ag⁺ + OH⁻

 

Ⅷ.Can LR44 replace 357 battery?

LR44 batteries and 357 batteries are similar in some respects, but due to different voltages and capacities, they are not directly interchangeable.

LR44 battery is usually 1.5 times, and 357 battery is 3 times. This means that there is a specific voltage required for installation, directly replaceable installation equipment malfunction.

LR44 batteries and 357 batteries have different capacities. Due to the equipment's demand, the large-capacity battery will continue to wear out, and the LR44 battery can be replaced, leading to battery exhaustion, which will affect the life of the equipment.

Due to differences in voltage and capacity, improper battery types can affect equipment performance, such as brightness and volume.

Exhaust LR44 batteries and 357 batteries can be similar in size, but the structure and composition are different, so it is not possible to legally match the installed battery.
