LR44 Battery Equivalents

In the battery world, different types of batteries have their own unique chemistries and uses.

First of all, alkaline batteries are known for their stable performance and mainly use zinc oxide as the negative electrode and manganese dioxide as the positive electrode. The nominal voltage of this type of battery is 1.5V, while the endpoint voltage is 1.0V. However, their voltage drops over time. Examples include LR44, 76A, AG13, LR1154, A76, L1154.

In contrast, Silver-Oxide batteries provide a very constant voltage, usually around 1.55V. This makes them ideal for devices that require stable power. SR44W, SR44, SR44SW, 157, 357, etc. are all such batteries.

Zinc-air batteries are known for their relatively low voltage and large capacity, usually between 1.4-1.45V. This type of battery is mainly used for devices such as hearing aids that require large capacity but relatively low voltage. 675, Blue Tab, ZA675, PR44, etc. are all such batteries.

Finally, mercury oxide batteries were no longer used because they contained mercury. They have a slightly lower voltage of 1.35V and may be labeled MR44, MR1154. This type of battery has been withdrawn from the market due to environmental and health concerns.

There are also differences in the capacity of various batteries. Alkaline batteries are generally 110-130mAh, silver oxide batteries are 150-200mAh, zinc-air batteries are 600-700mAh, and mercury oxide batteries are 180-200mAh.

Discharge Characteristics

Can I replace LR44 with AA?

While it is technically possible to use AA batteries as a substitute for LR44 batteries in certain situations, there are some important considerations and potential issues to be aware of.

• Size Difference

LR44 batteries are much smaller than AA batteries. The LR44 has a diameter of about 11.6mm and a thickness of about 5.4mm, while AA batteries have a diameter of about 14.5mm and a length of about 50.5mm. Physically fitting AA batteries into a device designed for LR44 may be challenging, and the larger size may not allow for proper contact.

• Voltage Difference

LR44 batteries typically have a voltage of 1.5 volts, while AA batteries have a nominal voltage of 1.5 volts as well. However, the capacity (mAh) of AA batteries is much higher than that of LR44 batteries. This could potentially lead to overvoltage issues, damaging the device or affecting its performance.

• Polarity and Connection

Connecting AA batteries to a device designed for LR44 may require modification of the battery compartment to ensure proper electrical contact. Additionally, ensuring the correct polarity is crucial to avoid damage.

• Risk of Leakage

Alkaline AA batteries have a higher capacity and may deliver a higher current than LR44 batteries. This could lead to increased heat generation, potentially causing leakage or damage to the device.

 

Can a 675 battery replace a LR44?

The 675 battery and LR44 battery have different sizes and voltages, so they are not direct replacements for each other.

 

LR44 Battery:

Voltage: 1.5 volts

Dimensions: 11.6mm diameter, 5.4mm thickness

675 Battery:

Voltage: 1.4 volts (zinc-air) or 1.45 volts (alkaline)

Dimensions: 11.6mm diameter, 5.4mm thickness (zinc-air), or 14.5mm diameter, 5.4mm thickness (alkaline)

 

While the dimensions of the 675 battery match those of the LR44, the voltage difference is significant. The LR44 operates at 1.5 volts, while the 675 battery typically operates at a lower voltage (either 1.4 volts for zinc-air or 1.45 volts for alkaline). This voltage difference may affect the performance of devices designed specifically for 1.5-volt LR44 batteries.

If a device explicitly requires a 1.5-volt LR44 battery, it's advisable to use the correct voltage to ensure proper functionality. Using a 675 battery with a lower voltage may result in reduced performance or improper operation of the device. 

 

Does 377 replace LR41?

Yes, you can use a 377 battery as a replacement for an LR41 battery. Both are coin cell batteries with similar dimensions (7.9mm in diameter and 3.6mm in thickness), and they have a nominal voltage of 1.5 volts. The key difference is in the chemistry: LR41 batteries are typically alkaline, while 377 batteries are silver oxide.

In many cases, silver oxide batteries like the 377 offer a longer lifespan and more stable voltage over time compared to alkaline batteries. The higher capacity and voltage stability of silver oxide batteries make them suitable for applications that require a steady and longer-lasting power source.

So, if your device originally used an LR41 battery, replacing it with a 377 battery should work, and you may even benefit from the extended lifespan provided by the silver oxide chemistry.
