CR1130 Battery Equivalents and Replacements

CR1130 is a button/coin 3.0V non-rechargeable lithium battery, typically used in remote controls, car keys, some watches, etc.

CR1130 battery is not a very common battery and can't be easily found in local hardware and similar stores. But it can be found at online stores ...

CR1130 Battery Features and Specifications

Lithium 3.0V CR1130 batteries feature physical dimensions of 11.5 x 3.0 mm (~0.4528 x 0.1181 inches), with a nominal voltage of 3.0V and a cutoff voltage of 2.0V.

A nominal capacity is usually in the 45-70mAh range, but that depends on the battery model, quality, battery age, and discharge current.

CR1130 battery standard discharge current is usually around 0.05 and 0.1 mA, with short pulse currents up to 4-5 mA.

Thanks to the Lithium Manganese Dioxide chemistry, CR130 batteries have a very low self-discharge rate, usually between 1-10% annually - this is big range, so if you are looking for a CMOS/memory backup CR1130 battery, be sure to read the batteries' datasheets in order to find actual self-discharge rates.

Note: again, CR1130 batteries are not very common, and they are not manufactured by most popular brands like Energizer, Duracell, Panasonic, Varta, etc., and finding all the required data for each model can be a daunting task...

Lithium non-rechargeable 3.0V button/coin 11.5 x 3.0mm battery has a standard label of CR1130, but other labels are used as well, including DL1130, BR1130, KL1130, L1130, EB-CR1130, ECR1130, KCR1130, E-CR1130, KECR1130, etc.

Notes:

• DL1130 would be a Duracell CR1130 battery, but Duracell is not manufacturing (at least not anymore) CR1130 batteries,
• BR1130 battery is a Carbon Monofluoride Lithium battery featuring a somewhat lower capacity and weaker discharge currents but also a lower self-discharge rate. Very rare battery.
• ECR would be an Energizer CR1130 battery, but Energizer is not manufacturing (at least not anymore) CR1130 batteries. Nonetheless, some manufacturers may use ECR1130 or similar labels for their own CR1130 batteries.

However, one must be aware that there is also an alkaline/silver-oxide battery with very similar dimensions and labels that are often used mutually.

LR1130/SR1130SW Batteries vs. CR1130 Batteries

LR1130/SR1130SW batteries and CR1130 batteries are physically very similar batteries with their most important features given in the following list:

• LR1130 battery: alkaline 11.6 x 3.1 mm, 1.5V nominal voltage, 0.8-0.9V cutoff voltage, 60-80mAh nominal capacity,
• SR1130SW battery: silver-oxide 11.6 x 3.1 mm, 1.55V nominal voltage, 1.2V cutoff voltage, 70-90mAh nominal capacity,
• CR1130 battery: lithium 11.5 x 3.0 mm, 3.0V nominal voltage, 2.0V cutoff voltage, capacity up to 70mAh.

Although CR1130, SR1130SW, and LR1130 batteries are physically interchangeable, they are not compatible. Never, but really never put the CR1130 battery in the battery compartment intended for LR1130/SR1130SW battery.

Due to the voltage difference, the device designed for LR1130/SR1130SW battery will probably be destroyed.

Only if the device's Owner's Guide explicitly says that the device accepts both 1.5V and 3.0V battery, only then one may replace LR1130/SR1130SW battery with a CR1130 battery.

Similarly, if you put LR1130/SR1130SW battery in the battery compartment intended for the CR1130 battery, the device will probably malfunction, or it won't start at all due to the lower voltage (~1.5V vs. 3.0V).

Thus, if you are looking for a 1.5V 11.6 x 3.1 mm battery, go for a 1.5V (LR1130) or 1.55V (SR1130) battery and stay away from the CR1130 battery.

Note: the "best of all" is that L1130 and similar labels some manufacturers use for their lithium (3.0V) 11.5 x 3.0V batteries, and some for their alkaline (1.5V) 11.6 x 3.1 mm batteries.

CR1130 battery is not a very common battery, and manufacturers offering their batteries with full PDF datasheets are even less common. Here are several CR1130 batteries with their most important features and specifications:

CR1130 Battery Safety Issues

Like most modern lithium batteries, CR1130 batteries don't contain mercury, cadmium, lead, and other heavy metals and toxic chemicals.

But, they are small, shiny objects that may attract kids and pets - thus, they are commonly sold in "kids safe" packages.

However, should the battery be swallowed, the body fluids may short-circuit the battery, causing various electrochemical reactions, including chemical burns.

If the CR1130 or any similar battery ever get swallowed, contact the nearest emergency center, explain what happened, and act according to their instructions.

Long Story Short: If you are looking for a lithium non-rechargeable 3.0V 11.5 x 3.0mm battery, go for a CR1130 battery and don't look for LR1130 (1.5V) or SR1130 (1.55V) battery.

When ordering from online stores, be sure to go for the models with many positive user reviews - better safe than sorry.
