Battery Equivalents: AG13/LR44/SR44/SR44SW/357

Button/coin cell batteries like AG13/LR44/SR44/SR44SW/357 are used in watches, calculators, and other small electronics.

The IEC standard is an international battery size designation, and it’s necessary to know the code for many batteries. LR1154 battery equivalent are alkaline batteries, and SR1154 refers to silver-oxide cells.

Some manufacturers have their own names for these batteries, adding the IEC and other standard codes. A two-digit code used is LR44 (alkaline) or SR44 (silver oxide). The first letter indicates whether it’s an alkaline battery or silver oxide; R=Alkali, S = Silver Oxide. These are followed by numbers that describe how many volts each size has in common with another.

Alkaline or silver-oxide are button/coin cell batteries with 11.6 mm in diameter and 5.4 mm in height and a capacity that depends on the used chemistry but can also be determined by cut-off voltage of the device.

Here are some pointers to help you remember:

  • If you’re looking for a replacement battery for AG13 and SG13 battery, it’s best to know the difference between these two batteries. AG13 is alkaline, while SG13 is silver oxide. However, sometimes manufacturers mark their products with both labels, so make sure the one that says “Silver Oxide” on it has this designation near its name or description to avoid confusion.
  • Remember the battery codes. When you’re trying to find out what kind of battery your small electronics device uses, the first thing you need is a code.

If the battery code starts with:

– for alkaline coin cell

– for silver-oxide

P – for zinc-air

M or N – for mercury-oxide. Please note that mercury’s hazardous nature and toxicity in these batteries are no longer being used for commercial purposes.

If the battery code ends with:

– most likely, the battery has potassium hydroxide electrolyte content.

– this battery has a sodium hydroxide electrolyte

In some cases:

If the battery code does not end with either P or S, batteries are most like to be organic in composition.

W after the digit – these batteries have an IEC 60086-3 watch battery standard on their packaging. They usually comply with this specific criterion as well.

Differences: AG13/LR44/SR44/SR44SW/357

As mentioned earlier, mercury-oxide batteries are no longer commercially available or were phased out due to their mercury content that has been shown to be harmful.

Zinc-air batteries have had a low voltage output compared to alkaline counterparts (1.4 V vs. 1.5V). However, these battery types are capable of storing 600 or 700 mAh, which makes them ideal in devices with large power demands such as digital cameras and MP3 players, among others.

Silver-oxide batteries are like a better version of alkaline ones because they have 1.55 volts instead of the regular 1.5, and while it’s being used, their voltage remains stable at around 12. Silver-oxide batteries are the best choice for powering smaller electronics. Alkaline batteries are cheaper and more versatile, but they don’t have enough voltage to power such devices. You know that silver-oxide batteries are more expensive than alkaline ones, but it’s worth the price difference when you consider their features and performance. In fact, in larger packages, there is hardly a cost difference at all between them.

Alkaline batteries are an excellent option for general use and small electronic devices. They’re cheap, reliable, have a decent capacity of 110-130 mAh, depending on the cut-off voltage of your device.

AG13 (i.e., Eurobatt): Alkaline battery with 1.5V, 0.9V nominal and cut-off voltages, 130 mAh capacity.

LR44 (i.e., muRata): Alkaline battery with 1.5V, 0.9/1.2V nominal, and cut-off voltages, 130 mAh capacity.

SR44 (i.e., muRata): Silver oxide battery with 1.55V, 1.2V nominal, and cut-off voltages, 155 mAh capacity.

357 (i.e., Energizer): Silver oxide battery with 1.55V, 1.2V nominal, and cut-off voltages, 150 mAh capacity.

SR44SW vs SR44 vs LR44: As a replacement for larger batteries

LR44/SR44/SR44SW batteries are much more versatile than you might think. They can be used to replace not just button 11.6×5.4 mm coin cells but also larger battery sizes too.

Lithium non-rechargeable CR11108 or CR1/3N batteries are typically used in watches, calculators, and children’s toys. They feature 3.0 nominal voltage and capacity between 160 to 170 mAh, just as many LR44 SR44SR 44SW.

CR11108 or CR1/3N batteries are mostly used in cameras, calculators, and PDAs. These types of battery packs use one 3V lithium-ion battery that is popular for its power density to replace two weaker 1.5 volts LR44 alkaline cells with a nominal voltage of only 3 volts each.

The 4LR44 and the 4SR44 are cylindrical batteries that display their internal construction on their exterior label.

4LR44/4SR44 batteries are the equivalent of four LR44 or SR44SW equivalent, joined together to create a battery with a nominal voltage of 6 volts. They typically have 110-150 mAh capacity for 4LR44 and 150-200 mAHD for 4SR440’s. The dimensions of these types of batteries are 25mm in height and 13 mm in diameter.

4LR 44/ 4 SR 44 are used in some film cameras, flashlights but not all types, and medical instruments. While easy on your wallet, these have a long life span, so make sure you buy them for all those electronics that need power.

The use of shiny, attractive-looking batteries should be a warning to all parents. These small LR44/SR44 and other similar size batteries are often used in children’s toys or household electronics like remote controls for televisions and even as key chain trinkets that kids have come to treasure dearly. But these harmless-looking batteries can cause serious harm if swallowed by curious pets or inquisitive young ones who will get into anything they want. This is why it is very important and necessary to keep them out of reach from little hands with lots more dangerous things around the house.

You might think that you are safe from the dangers of batteries because they don’t have mercury or other heavy metals, but button and coin batteries pose a threat to your health if swallowed. When these types of cells come in contact with stomach acid, it can create an electric current which leads to chemical build-up inside the body (especially when there is high sodium hydroxide concentration). This dangerous build-up causes damage quickly and often results in serious injuries or death. If accidents happen and a child has swallowed one of these batteries, seek medical attention right away.
