The LR1130 battery is a small, cylindrical coin or button cell battery commonly used in various portable and small-scale electronic devices. It's an alkaline battery, signified by the "LR" in its name, with standard dimensions of 11.6mm in diameter and 3.1mm in height. The battery operates at a nominal voltage of 1.5 volts and offers a capacity between 50 and 80mAh, dependent on the specific manufacturing processes and quality.
In summary, the LR1130 is a versatile and widely-used battery due to its compact size, reasonable capacity, and ability to power a diverse range of devices. Its numerous applications include wristwatches, calculators, toys, and even certain types of medical equipment, making it an important component in the world of compact electronic devices.
LR1130 Battery Parameters
The LR1130 battery, like other batteries, can be characterized by a few key parameters. Here are the most common:
Type: Alkaline button/coin cell.
Diameter: Approximately 11.6mm.
Height: Approximately 3.1mm.
Nominal Voltage: 1.5 volts.
Capacity: Typical range is between 50 to 80 milliamp-hour (mAh).
Expected Lifetime: Varies greatly based on device usage and battery quality, but often within a range of several months to over a year for low power devices like watches and calculators.
Besides the standard LR1130 label, this battery type can be found under multiple other names and specifications including AG10, 389, 390, KA54, and L1131, among others. These varying codes can lead to some confusion among customers, but they generally represent the same type of battery.
LR1130 Equivalent and Replacement Batteries
The LR1130 battery, due to its widespread usage, is produced by virtually all battery manufacturers. However, there is a considerable level of labeling diversity, including terms like LR1131, LR54, SR1130, SR1130SW, AG10, 390, 389, 387, and 189. This assortment of labels has led to some degree of confusion among consumers regarding battery replacement.
Equivalent batteries to the LR1130 also bear various designations such as AG10, D189, D389, D390, G10, G10A, 1159SO, 1168A, 189, 189-1, 280-15, 280-24, 389, 389A, 389BP, 390, 390A, 534, 554, 603, 615, 626, GP189, GP389, GP390, KA54, L1131, LR1130, LR54, R 389/17, R 390/11, RW 39, RW 49, RW49, RW89, S1131S, SG10, SP390, SR1130, SR1130SW, SR1130W, SR54, V389, V390, and WL10. Understanding this intricate naming system necessitates dissecting the alpha-numeric codes each battery bears:
LR1130: The prefix 'LR' signifies it's an alkaline battery with a standard voltage of 1.5V. '1130' indicates the battery's dimensions: a diameter of 11.6mm and a height of 3.0mm.
AG10: In this common button cell battery nomenclature, 'A' refers to alkaline and 'G' denotes a button cell. The '10' implies that it equivalates to the tenth battery size in the AG series.
D389/D390: Typically, these are Duracell's codes for their versions of LR1130 batteries. D389 and D390 are fundamentally identical batteries, although D390 may often offer a marginally higher capacity.
SR1130: The 'S' prefix indicates a silver-oxide battery type, providing a nominal voltage of 1.55V, aside from a size identical to that of the LR1130.
Numerical codes (390/389/387/189): Resonating with the IEC's (International Electrotechnical Commission) battery labeling scheme, these codes capture the battery's primary attributes. The initial one or two digits signify the electrochemical system; subsequent two digits denote the battery's diameter, and the final two digits refer to the battery's height.
LR1130 Battery vs LR44 Battery
Parameter
| LR1130 | LR44 |
|---|
| Diameter (mm) | 11.6 | 11.6 |
| Height (mm) | 3.1 | 5.4 |
| Nominal Voltage (V) | 1.5 | 1.5 |
| Chemistry Type | Alkaline | Alkaline |
| Capacity (mAh) | Lower (varies by brand) | Higher (varies by brand) |
| Common Uses | Watches, calculators, small electronic devices | Watches, calculators, thermometers, some toys and small electronic devices |
The LR1130 and LR44 are both types of button/coin batteries commonly used for a wide range of small electronic devices, but they do have some differences, primarily in terms of their size and capacity:
LR1130 vs LR44 Battery: Size
The primary difference between these two batteries lies in their physical dimensions. The LR44, also referred to as AG13, has a diameter of approximately 11.6 mm and a height of about 5.4 mm. On the other hand, the LR1130 (or AG10) is a bit thinner with similar diameter around 11.6 mm but a height of roughly 3.1 mm. The thinner profile of the LR1130 makes it suitable for applications where a slimmer battery is necessary, while the thicker LR44 offers more capacity for applications that have sufficient space and require a bit more energy.
LR1130 vs LR44 Battery: Capacity
Generally, the LR44 battery has a slightly higher power capacity compared to the LR1130 because it is thicker and hence contains more cell material. This could mean a longer lifespan for the same usage. However, the actual longevity also depends on the device's power consumption.
LR1130 vs LR44 Battery: Voltage
Both batteries deliver a nominal 1.5V.
LR1130 vs LR44 Battery: Chemistry Type
Both LR1130 and LR44 are LR batteries, meaning they are alkaline. Their silver equivalent would be SR1130 and SR44, which typically have longer life but also higher cost.
LR1130 vs LR44 Battery: Interchangeability
They are not usually interchangeable because of the size difference, unless the device’s battery compartment has certain flexibility to accommodate different height.
These are basic comparisons, and it's always recommended to follow the manufacturer's recommendation for exact battery model to ensure optimal performance.
Frequently Asked Questions
1. Can 357 Battery Replace LR1130?
No, The 357 or SR44 is a silver-oxide type battery, and it generally provides a longer lifespan compared to the alkaline LR1130, but the size and voltage are different. The 357/SR44 has a diameter of 11.6 mm and a height of 5.4 mm, while the LR1130 has a diameter of 11.6 mm and a height of 3.1 mm. So, although the SR44/357 and LR1130 batteries offer the same voltage, the difference in size means they use different battery compartments and the batteries will not fit properly.
2. What Battery is Equivalent to LR1130?
Several types of batteries can be considered equivalent to the LR1130. These include AG10, LR54, 189, SR1130 (silver oxide version), and others.
