Can I use AA batteries instead of LR44?

Since LR44 is alkaline, AAs or AAAs are a one to one replacement. Solder the wires, in correct polarity, to the springs that make contact to the LR44. Or you could just strip the wires and twist them around the springs, then insert something in the battery compartment to hold them in place…

Is there another name for LR44 battery?

AG13 batteries Alkaline Zinc Manganese button batteries are used mainly in watches. Also called LR44, 157, A74 or LR 1154, they are equivalent in size and voltage to the SR44 batteries, also called 357.

Is AG13 same as LR44?

LR44 batteries, which are also known as either AG13 or A76 batteries, are generally a very popular type of battery and can be found in devices such as calculators, small electronic toys and digital thermometers.

Which is better alkaline or silver oxide?

Also, silver-oxide batteries under the same conditions, on average, feature 10-40% larger capacity – due to the more stable output voltage and larger capacity, silver-oxide batteries feature ~15-50% better energy density when compared with the alkaline batteries.

SR44 and LR44 Batteries

Generally, SR44 and LR44 batteries are mostly used in small remotes, wristwatches, and small toys. Despite having the same features and physical dimensions, they are slightly different from each other. For example, they operate with a distinct chemical process. Besides, they have different electrical characteristics as well.

Features and Specification of SR44 and LR44

As I said before, SR44 and LR44 use different chemical mechanisms. This difference makes a slight dissimilation between them. For example, LR44 batteries, which use Alkaline, have 1.5 V as nominal voltage. On the contrary, SR44 batteries, which use Silver-oxide, have 1.55 voltage. Yet, this difference is so less to count.

Which One is Better Between SR44 and LR44

It is hard to select one between SR44 and LR44. Yet, silver oxide performs better than alkaline in some cases. In this regard, you may consider SR44 better. Besides, the capacity of silver oxide is 50 percent to 100 percent more than alkaline.

Are SR44 and LR44 Batteries Interchangeable

Despite having a different chemical mechanism, they can use interchangeably in the same compartment. Because both of the batteries detail is similar and 1.55mm in diameter. Furthermore, some manufacturers’ companies notify that it would not harm the application when you use them interchangeably.

Frequently Asked Question

Generally, LR44 and SR44 batteries are used in cameras, medical devices, flashlights, and similar applications. Besides, these batteries are also suitable for widescreen and multiscreen. Furthermore, you can use these alkaline and silver oxide batteries for small applications, such as wristwatches and toys.


Similarities are clear but the distinction: SR44 vs LR44 battery differs the application. In short, you can use both interchangeably with a negligible effect.

How long do LR44 batteries last?

The shelf life of AG13, LR44, SR44, SR44SW, and 357 depends on their quality and the manufacturer’s use of quality raw materials and chemicals. In general, good quality Alkaline batteries have a shelf life of five years. In comparison, Silver-oxide batteries have a longer shelf life, estimated to be approximately ten years or more. This large capacity also balances a sturdy voltage while working, and the power doesn’t drop.

How big is a LR1154 battery?

The alkaline LR1154 and the silver-oxide SR1154 are both 5.4 mm in height and 11.6 mm in diameter . The capacity of power of these batteries depends on the chemical compositions used, which can be known through the labels. It also depends upon the capacity and the power usage of the device that they are meant to power.

What is the LR1154 label?

Although for silver-oxide, G13 ‘SG13’ label should be used. The IEC standards state that AG13 should be named LR1154 if it is alkaline or SR1154 if the composition is silver-oxide. May times, its short two-digit code is also applied to labels like LR44 for alkaline compositions and SR44 for Silver-oxide batteries.

What is the label for a silver oxide battery?

However, the way these button, coin, or cell batteries are labeled might cause confusion to the buyer. This confusion is due to the use of the same label for both silver oxide battery and alkaline battery, such as the label ‘AG13 is used for both Alkaline G13 and Silver-oxide G13. Although for silver-oxide, G13 ‘SG13’ label should be used.

What is the difference between silver oxide and alkaline batteries?

The nominal voltage of an Alkaline battery is 1.5V, whereas the nominal voltage of Silver-oxide is 1.55V. In contrast, Zinc Air has 1.4V to 1.45V, and mercury-oxide has 1.35V. This range makes mercury-oxide the lowest in nominal voltage.

What batteries are used in flashlights?

AG13, LR44, SR44, SR44SW, and 357 coin, button, or cell batteries are very well known as they are used in various devices. These are essential for mini flashlights, wristwatches, calculators, and other small appliances needing limited power. They are also used in mini electronic devices.

How many mAh is an alkaline battery?

The capacity of an Alkaline battery is 110-130 mAh, whereas the capacity of Silver-oxide is 150-200 mAh. In contrast, Zinc Air has 600-700 mAh capacity, and mercury-oxide has 180-200 mAh capacity. This range makes alkaline batteries the lowest with regard to capacity.
