AG13, SG13, LR1154, SR44, SR44SW, 303, 357, A76, LR44 Battery Equivalents and Replacements

AG13/LR44/SR44/SR44SW/357 button/coin cell batteries are very popular batteries, commonly found in wrist watches, small flashlights, calculators, some remote control devices, thermometers, laser pointers, and other small electronic units.

According to the IEC standard, this battery should be called LR1154 (alkaline) or SR1154 (silver-oxide). Sometimes shorter, two-digit code is used: LR44 for alkaline and SR44 (or SR44SW) for silver-oxide batteries.

Many manufacturers use their own names for these batteries, but they also tend to add IEC and other standard codes, including short descriptions of the chemistry and other important features.

Updated: August 18, 2022.

LR44/SR44 Battery Features and Specifications

LR44/LR1154 (alkaline) or SR44/SR1154 (silver-oxide) batteries are button/coin cell batteries 11.6 mm in diameter and 5.4 mm in height. Their capacity depends on the used chemistry but also on the cut-off voltage of the used device.

What is the Voltage of an LR44 Battery?

The voltage of LR44 and other buttons/coin 11.5×5.4 mm batteries depends on the exact battery chemistry, the battery age, temperature, current capacity, etc.

In most situations, nominal voltage is the open-circuit voltage of a brand new battery at room temperature. as soon as the battery is being discharged, the battery voltage drops.

Mercury-oxide batteries are no longer in use due to the mercury content, which is not the most environment-friendly metal. to say the least.

Zinc-air batteries have slightly lower voltage (1.4 V vs. 1.5 V) when compared with alkaline batteries, but they have a rather large capacity of 600-700 mAh.

These batteries use oxygen from the air and wet electrolyte. prior to the use, the tab is removed, and the air enters the battery. However, when electrolyte dries out, the battery is dead even if it hasn’t been depleted by the use.

The price of the battery is acceptable and not higher than the price of other LR44/SR44 batteries.

Silver-oxide batteries have a slightly higher nominal voltage (1.55 V vs. 1.5 V) when compared with alkaline batteries, but unlike alkaline batteries, this voltage remains fairly constant during use, with a cut-off voltage around 1.2V.

Also, silver-oxide batteries have a larger capacity when compared with alkaline batteries.

These batteries are the preferred choice for powering watches, calculators, and similar small electronic devices. Such devices can have reliability issues when being powered by alkaline batteries due to the voltage drop.

Silver-oxide batteries cost slightly more than alkaline batteries, but their features and performances IMHO justify the price difference. When buying larger packages, the price difference is usually negligible.

Alkaline batteries have been on the market for a long time. they are cheap and reliable and have a decent capacity of 110-130 mAh.

Since their voltage drops during use, their capacity depends on the device’s cut-off voltage. if it is some digital watch that signals at 1.2V battery voltage that it is time to change the battery, then these batteries are not recommended for such devices.

But, they are good to go for general use in toys, small flashlights, and similar applications.
