LR1130 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.

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), nominal voltage of 1.5 volts, 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 source of power, 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.

SR1130SW 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 SR1130SW batteries were manufactured as either 'low-drain' or 'high-drain' batteries for powering different devices. 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 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.

The following comparison chart lists some of the most common alkaline and silver-oxide 11.6 x 3.1 mm batteries with their most important features and specifications:

Capacity Operating Temperature Annual Self-Discharge Rate Discharge Current

Energizer 189 80 mAh, 15 kΩ down to 0.9V @21°C - - 83μA over 15kΩ @1.25V @20°C
Energizer E390/389 88 mAh, 15 kΩ down to 1.2V @21°C - ~2% @20°C 99μA over 15kΩ @20°C

Of course, there are other alkaline and silver-oxide 11.6 x 3.1 mm batteries on the market as well.

CR1130 battery, also sometimes labeled as DL1130, BR1130, KL1130, L1130, etc. is a manganese-dioxide lithium battery (CR1130) or carbon-monofluoride lithium battery, featuring nominal voltage of 2.8V (BR1130) to 3.0V (CR1130) 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 that both voltages (1.50/1.55 volts and 2.8/3.0 volts) are allowed/supported.

LR1130/SR1130/CR1130 Batteries Safety Issues

As with 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, contact immediately nearest emergency center, explain what happened and act according to the instructions.

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 shelf life is 2-3 years.

For more sensitive applications like wristwatches, calculators, 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.

Again, keep these batteries away from pets and kids, and be sure to recycle them properly.
