Typically, AG13, L1154, LR1154, and 157 are some of the most commonly used substitutes for LR44 batteries. You have arrived at the right website if you want to learn more about LR44 batteries and would like to purchase a few of them.
What Is Lr44 Battery?
The LR44 battery is a button cell battery that contains Alkaline Zinc Manganese acid. LR44 battery voltage is dependent on several things. In most cases, the LR44 battery is 1.5 Volts with an operating temperature range of 0°C to 60°C, with 20°C being the ideal temperature.
For the most part, nominal voltage is the open-circuit voltage of a brand-new battery at room temperature, which declines when the battery is being depleted.

Understanding the Battery Labels on Coin Cells
One may quickly ascertain the chemistry of a button or coin cell battery by reading the label on the battery below:
- LR stands for an alkaline battery, which is commonly LR44 or LR1154;
- SR stands for silver-oxide battery, which is commonly SR44 or SR1154;
- PR – zinc-air battery, generally PR44 in configuration;

There may be letters after the numbers on the battery label. Electrolyte type and battery drain are indicated by these letters:
- P: electrolyte of potassium hydroxide (KOH);
- S: electrolyte of sodium hydroxide (NaOH);
- SW: low draw-type – usually used in Silver-Oxide batteries, such as the SR44SW;
- W: high drain type – typically used in Silver-Oxide batteries, such as the SR44W.
Lr44 Battery Equivalent Type
LR44 battery replacements are available in A76, AG13 LR1154, and 157. Other batteries, like the SR44, have a similar design but a different chemical. The LR44 battery is the same size as silver oxide button cells as the SR44, SR44SW, 303, and 357. To prevent any complications, read the following details of LR44 batteries replacements.
Alkaline (LR44 and LR1154)
Many people use LR44 alkaline batteries because of their low price and high capacity (110-130 mAh). Using these batteries with a digital watch with a battery voltage indicator indicates it is time to replace the battery at 1.2V. For example, Hill flower LR44/LR1154 can safely utilize toys, small flashlights, and similar devices.
Silver-Oxide (SR44 and SR44W)
It is well known that silver-oxide batteries have a steady discharge, and they are commonly employed in medical and precision instruments. Batteries like the SR44, SR44SW, 303, and 357 are all identical in size but differ in chemistry from the LR44. Rayverstar LR44/SR44SW supplies an excellent mixture of high energy and constant voltage.
It exclusively covers alkaline LR44 and silver-oxide SR44 batteries. Hearing aids usually use zinc-air batteries, which are remarkable despite their lower voltage. Because they require wet/moist electrolytes and air, PR44 is uncommon in other electronic equipment. The most popular PkCell PR44 has a capacity of 630 mAh.
Mercury Oxide (MR44 and MR1154)
Despite their consistent voltage, mercury-oxide batteries are no longer used due to their toxicity. Batteries that are disposed of incorrectly can harm our natural resources.

Comparing Alkaline LR44, Silver-oxide SR44, and Zinc-air PR44 Batteries in Detail
An alkaline LR44 battery’s voltage is 1.5 volts, although it has a cutoff voltage of 0.9 to 1.0. Some LR44 batteries, like LiCB LR44, claim to have a capacity comparable to silver-oxide batteries, despite their standard capacity being in the 110 to 130 mAh range. So, will a 357 battery replace an Lr44? No, their size is the same, but the chemistry is different; LR44 is alkaline, and 357 is silver oxide.
In addition, the real capacity of these batteries is affected by the cutoff voltage of the devices that use them. For example, when the battery voltage dips below 1.2 volts, some watches experience dependability concerns. SR44 batteries can power these and other similar devices.
While the output voltage of alkaline LR44 batteries declines significantly after discharge, the output voltage of silver-oxide SR44 batteries does not drop nearly as much as the voltage of alkaline batteries. As a result, SR44 batteries are the go-to option for devices that require a relatively steady output voltage, such as watches and some medical devices.
Silver-oxide batteries also have a higher nominal capacity, typically 150-200 mAh, and Low-drain batteries can claim to have more than 200 mAh of capacity. The self-discharge rate of the SR44 battery is extremely low, with most models having a shelf life of 5-7 years and some having a shelf life of 7-10 years.
On the other hand, the PR44 battery is generally referred to as “Blue Tab” and is mainly used in hearing aids. This battery has a lower beginning voltage (often labeled as 1.45 volts) and a relatively steady output voltage during discharge. PR44 batteries have the largest capacity of all chemistries in the 600-700 mAh range, nearly three to four times greater than silver-oxide batteries.
On the other hand, Zinc-air batteries have a ‘small issue’ – their electrolyte is ‘wet,’ and they utilize oxygen from the air to generate energy (thus the moniker ‘zinc-air’). Zinc-air batteries have a colorful tab that must be peeled off before use (each zinc-air battery size has a different colored tab). In a matter of seconds after the tab has been removed, air (oxygen) is let into the battery, causing it to begin producing voltage and power.
No matter what type of LR44 battery you need – SR44, PR44, or any other variation – always go with a recognized brand, even if it means paying a little more. Because, after all, these brands are referred to as “reputable” for a good reason.

1. What Does LR in Batteries Mean?
LR stands for round alkaline and CR for round lithium. The first letter indicates battery type, and the second letter indicates shape. So, R means round.
2. How Long Does an LR44 Battery Last?
LR44 batteries typically last 6 to 8 years, depending on the different brands.
3. Is an LR44 Battery the Same as a 357?
Both the 357 and LR44 are silver oxide batteries. But 357 batteries last longer and maintain a more constant voltage than LR44 batteries.
4. What Duracell Replaces LR44?
The Duracell 76A is a direct replacement for the LR44, and the only difference between the two is the name.
5. Is LR44 better than SR44?
LR44 and SR44 are used for different purposes. Because of its lower cost, LR44 is a preferable choice for toys and other general-purpose applications. SR44 batteries are ideal for the marine and other high-end electronic devices.
If you’re thinking about getting a new LR44 battery equivalent, you’ll first want to brush up on your expertise. In this post, I aim to assist you in making an informed decision on the LR battery equivalent and its purpose.
However, before switching out SR44 batteries with LR44 or another type, be sure to read the equipment’s manual and comprehend its parameters.
