LR1130, AG10, 389, 390 Battery Equivalents and Replacement
LR1130 is a very popular button/coin cell battery, often used in remote controls, car keys, garage openers, micro LED flashlights, calculators, toys, etc.
Since it is so popular, practically all battery brands manufacture LR1130 batteries, but they also use many other labels, including LR1131, LR54, SR1130, SR1130SW, AG10, 390, 389, 387, 189, etc., leading to certain confusion among the consumers.
The most commonly used labels are LR1130, AG10, 389, and 390 batteries.

LR1130 Battery Features and Specifications
LR1130 battery is an alkaline button/coin cell battery with physical dimensions of (D x H) 11.6 x 3.1 mm (0.4567 x 0.1220 inches), a nominal voltage of 1.5 volts, a cutoff voltage of 0.8-1.0 volts, and nominal capacity between 50 and 80 mAh.
As with all similar batteries, the LR1130 battery's capacity depends on the current drain and actual cutoff voltage of the powered device.
Other most common labels used for alkaline 11.6 x 3.1 mm batteries are LR1131 (IEC standard), AG10, LR54, alkaline 189, alkaline 387, alkaline 389, alkaline 390, etc.
Note: when using numerical labels, not all manufacturers state that the battery is alkaline. In that case, check the labels containing letters (LR - alkaline battery, SR - silver oxide battery, CR - lithium battery) and nominal voltage (1.50V - alkaline battery, 1.55V - silver oxide battery, 3.0 volts - lithium battery).
LR1130 batteries are cheap and reliable power sources, but they feature a relatively short storage life (2-3 years), and their output voltage drops rather quickly.
Because of that, sensitive electronics and standby devices are commonly powered by silver-oxide 11.6 x 3.1 mm batteries.
SR1130 battery is a silver-oxide 11.6 x 3.1 mm battery featuring a nominal voltage of 1.55 volts and a capacity between 80 and 100 mAh.
Years ago, most SR1130 batteries were manufactured as either "low-drain" or "high-drain" batteries for powering different devices.
- SR1130W or 389 battery: High Drain battery, suitable for analog and digital watches with alarms and LED lights,
- SR1130SW or 390 battery: Low Drain battery, not the best choice for watches with alarms and lighting, but with improved operating lifetime over SR1130W/389 battery.
Thanks to the advances in electronics and chemistry, most modern SR1130 batteries are designed as "multi-drain" batteries and are good for powering both low-drain devices (wristwatches, for example) and high-drain devices (remote controls, toys, micro-Led flashlights, for example).
Other most common labels used for silver-oxide 11.6 x 3.1 mm batteries include SR1131 (IEC standard), SR1131SW, SR1130, SR1130W, SR54, 189, 387, 389, 390, SG10, etc.
Although SR1130 batteries are slightly more expensive than LR1130 batteries, SR1130 features a larger capacity, more stable output voltage, and longer shelf life (4-6 years, sometimes even more) and are thus more suitable for sensitive electronics, standby devices, EDC devices, wearable electronics and similar.

LR1130 Battery vs. CR1130 Battery
CR1130 battery, also sometimes labeled as DL1130, BR1130, KL1130, L1130, etc., is a manganese-dioxide lithium battery (CR1130) or carbon-monofluoride lithium battery (BR1130), featuring nominal voltage of 2.8V (older BR1130 batteries) to 3.0V (CR1130 and newer BR1130 batteries) and physical dimensions of (D x H) 11.5 x 3.0 mm (0.45275 x 0.11811 inches).
Although CR1130/BR1130 batteries may fit easily into the battery compartments intended for LR1130/SR1130 batteries, LR1130/SR1130 batteries should NOT be replaced with CR1130/BR1130 batteries unless explicitly allowed by the device manufacturer - the voltage differences, 1.50/1.55 volts vs. 2.8/3.0 volts may easily damage sensitive devices which don't allow such battery replacement.
LR1130/SR1130/CR1130 Batteries Safety Issues
Like all similar small batteries, LR1130/SR1130/CR1130 should be kept away from kids and pets - batteries are small enough to be swallowed.
Although modern LR1130/SR1130/CR1130 batteries feature 0% of mercury and other heavy metals (cadmium, for example) and as such, they are not poisonous, button/coin cell batteries, when swallowed, can cause electrolytic reactions creating chemical burns inside human/pet body.
If LR1130/SR1130/CR1130 or any similar battery gets swallowed, immediately contact the nearest emergency center, explain what happened, and act according to the instructions.
How to Properly Dispose of LR1130 and Equivalent Batteries?
Proper disposal of LR1130 batteries and their equivalents is very important for environmental safety and compliance with local regulations. These button cell batteries, often found in watches, calculators, and small electronic devices, contain materials that may be harmful if not handled correctly.
The first step in disposing of LR1130 batteries is to check with your local waste management authorities. Many regions have specific guidelines and facilities for recycling or safely disposing of batteries. This ensures that the batteries are handled in a way that minimizes environmental impact.
For instance, recycling facilities may be able to recover valuable materials like mercury, silver, and lithium, which are commonly found in these types of batteries.
If recycling is not an option in your area, you should look for a household hazardous waste (HHW) facility. These facilities are equipped to handle materials that are dangerous to throw away with regular trash. It's important not to dispose of LR1130 batteries in the household garbage or recycling bins as they can leak harmful chemicals over time.
Also, many retailers and public institutions offer battery recycling programs. These are often available at no cost and provide an easy and responsible way to dispose of used batteries. Keeping an eye out for these programs can be a convenient way to ensure your batteries are disposed of properly.
LR1130, AG10, 389, 390 Battery Frequently Asked Questions (FAQ)
Here are some of the most common Frequently Asked Questions (FAQ) about LR1130 and similar batteries.
What battery is equivalent to LR1130?
LR1130 is an alkaline 11.6 x 3.1 mm battery and is equivalent to the LR54 and AG10 batteries.
Since silver-oxide and alkaline button cells are compatible, the LR1130 battery can be replaced with an SR54 or SR1130 battery, also labeled 389, 390, SR1130W, SR1130SW, and similar.
Just be aware that 389/SR1130W are High-Drain batteries, and 390/SR1130SW are Low-Drain batteries.
Is the LR1130 battery the same as the 389?
No, they differ in chemistry and discharge features, but nonetheless, the alkaline LR1130 battery can be replaced with a silver-oxide low-drain 389/SR1130W battery in low-drain applications.
Are LR1130 and LR44 batteries the same?
No, LR1130 and LR44 batteries are not the same, though they’re sometimes confused because they’re both small, round, 1.5V alkaline button cells. The LR44 is thicker at 5.4mm vs the LR1130 at 3.1mm. They share the same diameter, voltage, and chemistry.
What does LR mean on a battery??
The "LR" marking on a battery tells you both the chemistry and shape of the battery. The L means it has an alkaline chemistry. The R means it is a round shape (coin or button shape). So, LR = Alkaline Round battery.
What battery can replace AG10? What is equivalent to AG10?
AG10 is an alkaline 11.6 x 3.1 mm battery and is also labeled as an LR1130 or LR54 battery. But, it can also be replaced with the silver-oxide SR1130/SR54 multi-drain battery.
Is LR44 the same as AG10?
No, the LR44 battery is an alkaline 11.6 x 5.4 mm battery, also labeled as an AG13 battery, while the AG10 battery features physical dimensions of 11.6 x 3.1 mm.
AG10 battery can fit the battery compartment intended for the LR44 battery, but loose contacts (if any) will prevent reliable operation. Also, AG10 has a lower capacity and drain currents than the LR44 battery.
Long Story Short: If You are looking for an LR1130 battery, go for an alkaline LR1130 (or LR54, LR1131, AG10, etc.) battery from a reputable brand, just be sure that You don't stack them too much - their not too long shelf life is 2-3 years.
For more sensitive applications like wristwatches, calculators, medical devices, and similar, SR1130 (or SR54, SR1131, SG10, 189, 387, 389, 390, etc.) batteries are recommended due to the larger capacity, more stable voltage, and longer shelf life. Most common small electronics such as laser pointers should work well with this battery especially when purchasing them in packs.
