What is an AG13 Battery?

AG13 battery watches mostly utilize alkaline zinc manganese button batteries. They are equivalent in size and voltage to the SR44 batteries, also known as 357, and are also known as LR44, 157, A74, or LR 1154. The latter, on the other hand, are Silver Oxide batteries, which have a capacity of nearly three times that of the former at a similar price.

The chemical formula for alkaline zinc manganese is (-) / MnO2 (C) (+) Zn MnO2. AG13 batteries are also known as LR44, 157, A76, and LR1154 in the industry.

The standard voltage of AG13 battery or LR44 battery is 1.5 volts, with a termination voltage of 0.9 volts. They have a 130mAh capacity. The cell is 11.6 x 5.4mm in dimension. You can see more detail in amazon.

LR44 vs. AG13 batteries: what’s the difference?

The batteries are identical, although they have different names:

The AG13 battery, sometimes called the LR44 battery, is a zinc manganese alkaline button battery. The following are its parameters:

• AG13/LR44 is the battery model.
• 1.5V standard voltage; 0.9V termination voltage
• 130 pound capacity (mAh)
• 11.6 x 5.4 cell size (mm)
• -10 C + 60 C working temperature; -10 C + 25 C storage temperature
• Zn MnO2 main battery. Chemical composition: Zn (-) / MnO2 (C) (+)

The names of button cells vary, but the battery specifications are the same. AG13 is also known as LR1154, A76, LR44, SR44, and 357.

What Are the Differences Between LR44, AG13, and A76?

The LR44, AG13, and A76 have significant commonalities that allow them to be used interchangeably. The physical size is the most evident comparison. Any battery meant to replace an LR44 should have a diameter of 11.6mm and a thickness of 5.4mm to meet international requirements. The size is crucial, since even a minor change will prevent the battery from fitting into many of the small devices for which it was built.

Alkaline chemistry

Alkaline is the most common chemistry for these three battery types. The AG13 battery and A76 battery designations, on the other hand, might deviate from the norm because they are manufacturers’ component numbers.

The silver oxide chemistry, for example, is used in an Energizer AG13 type battery. A silver oxide battery can live up to three times longer than an alkaline battery of comparable capacity.

The expense of silver oxide batteries is a disadvantage. They are more expensive than alkaline equivalents, however depending on how the batteries are utilized, a balance can be reached.

1.5 – 1.55 volts voltage

When fresh, all kinds of this battery produce 1.5 or 1.55 volts. The way the voltage drops during use is a crucial consideration. During the life of a normal alkaline battery, the voltage drops to roughly 1 volt. Silver oxide versions are more costly, but they have more stable voltages over time, usually maintaining at least 1.2 volts.

Non-Rechargeable

None of these batteries are rechargeable, and attempting to do so is harmful.

Are LR44 and AG13 and A76 the same thing?

This question does not have a straightforward yes-or-no response! The LR44 designation is an international standard (IEC 60086-3) that specifies the battery size and chemistry. The power is provided by alkaline chemistry in L batteries; in the case of the LR44, it is zinc-manganese dioxide.

This battery’s standard physical size is defined by the R44 code.

Both the manufacturer’s component numbers AG13 and A76 are for batteries that can be used instead of LR44 batteries. Despite the fact that they are the same size as the LR44, the internal chemistry employed might differ, affecting battery life.

Company that manufactures

It’s possible that you have a favorite brand. Perhaps you’ve tried every brand and discovered one that lasts longer or performs better than the others. For various products, different manufacturers utilize different component numbers.

This might be due to the fact that the battery isn’t a regular LR44 and has a different chemical composition. Another reason is that the firm wants to distinguish their battery from all other LR44 batteries.

If the battery is a branded replacement for an LR44, the packaging will state so, and the differences will be explained.

Dimensions of the AG13 battery

The voltage will always be 1.55 volts, but the capacity of the battery will change. LR44 batteries have an average power of 110 to 130 milliamperes.

This is dependent on the type of chemistry utilized and the component quality. Silver oxide batteries may yield between 150 and 200 mAh, which means they can last longer. In most circumstances, purchasing a branded product over a generic item will result in a more powerful battery, but it will cost more.

Pricing

The cheapest batteries are those that employ the common LR44 alkaline chemistry, however this is because they are less expensive to create and don’t last as long. A pack of ten LR44 type batteries costs little over $3, but the silver oxide types are much more expensive.

Last Words

The AG13, LR44, and A76 battery types are quite similar and may be used interchangeably in many situations. For most applications, the LR44 variety will be adequate, but for more power and more constant voltage output, search for silver oxide AG13 and A76 battery variations.
