These batteries are the preferred choice for powering watches, calculators, and similar small electronic devices. 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.Īlso, silver-oxide batteries have a larger capacity when compared with alkaline batteries. Silver-oxide batteries have a slightly higher nominal voltage (1.55 V vs. The price of the battery is acceptable and not higher than the price of other LR44/SR44 batteries. However, when electrolyte dries out, the battery is dead even if it hasn't been depleted by the use. These batteries use oxygen from the air and wet electrolyte - prior to the use, the tab is removed, and the air enters the battery. 1.5 V) when compared with alkaline batteries, but they have a rather large capacity of 600-700 mAh. Zinc-air batteries have slightly lower voltage (1.4 V vs. 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. 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. The voltage of LR44 and other buttons/coin 11.5x5.4 mm batteries depends on the exact battery chemistry, the battery age, temperature, current capacity, etc.

Slightly lower voltage, contains mercury AG13/LR44/SR44/SR44SW/357 Battery Chemistries Comparison ChartĬomparison and examples of the button/coin 11.6 x 5.4 mm cell batteries are given in the following table.

#G13A BATTERY CODE#

if the battery code after the digits contains 'W', then the battery complies with the IEC 60086-3 watch batteries standard. if the battery code after the digits doesn't contain 'P' or 'S', then most probably that battery contains an organic electrolyte. if the battery code after the digits contains 'S', then it is the battery with sodium hydroxide electrolyte. if the battery code after the digits contains 'P', then it is the battery with potassium hydroxide electrolyte. However, due to the presence of mercury, these batteries are no longer in use.

if the battery code starts with the 'M' or 'N', then it is a mercury-oxide coin cell. if the battery code starts with the 'P', then it is a zinc-air coin cell. if the battery code starts with the 'S', then it is a silver oxide coin cell. if the battery code starts with the 'L', then it is most probably an alkaline coin cell. However, sometimes manufacturers mark silver-oxide batteries with both SG13 (correct) and AG13 (not so correct) to emphasize that their battery is a replacement for AG13/LR44/LR1154 battery. AG13 vs SG13: AG13 should be 'alkaline G13,' and SG13 should be 'silver-oxide G13' battery. Their capacity depends on the used chemistry but also on the cut-off voltage of the used device. 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. LR44/SR44 Battery Features and Specifications
