Several alternatives exist for these battery types:

• LR44 Alternatives: A76, AG13, L1154.
• SR44 Alternatives: 303, 357, SR44SW.

These substitutes may vary in performance based on their chemistry; for example, while an A76 can replace an LR44 in many cases, it may not perform as well in high-drain devices.

Why choose silver oxide batteries over alkaline batteries?

Silver oxide batteries like the SR44 offer several advantages over alkaline options:

1. Stable Voltage: They maintain a consistent voltage throughout their discharge cycle.
2. Higher Capacity: Typically providing more energy storage (150–200 mAh).
3. Longer Shelf Life: Silver oxide batteries can last up to five years when stored properly.

These qualities make silver oxide batteries better suited for high-drain devices such as watches or medical instruments.

What are the common applications for these batteries?

LR44 and its equivalents are commonly used in:

• Calculators
• Laser pointers
• Toys

SR44 batteries find their applications primarily in:

• Digital watches
• Hearing aids
• Medical devices

Understanding where each battery type is used helps in selecting the right replacement.

How can I select the best alternative battery?

When choosing a replacement battery:

1. Check Compatibility: Ensure that the dimensions match your device requirements.
2. Consider Chemistry: For high-drain devices, opt for silver oxide over alkaline.
3. Evaluate Capacity Needs: Higher capacity translates to longer usage times.

Q: What is the shelf life of silver oxide vs alkaline batteries?
A: Silver oxide batteries typically last up to five years while alkaline variants last about three years.

Q: Are there any risks associated with using incompatible battery types?
A: Using incompatible types may lead to device malfunction or damage due to voltage discrepancies or inadequate power supply.

Is an LR44 the same as a 357? Can a 357 battery replace an LR44?

No, LR44 and 357 batteries are not identical, although they are often interchangeable. The LR44 is an alkaline 11.6 x 5.4 mm button/coin cell battery, while the 357 is a high-drain silver-oxide battery of the same size. While LR44 batteries are typically cheaper, they also have a higher self-discharge rate, lower capacity, and less stable voltage compared to 357 batteries.

Is LR44 the same as CR2032?

No, the LR44 is an alkaline button cell battery measuring 11.6 x 5.4 mm with a nominal voltage of 1.5V, whereas the CR2032 is a lithium coin cell battery measuring 20 x 3.2 mm with a nominal voltage of 3.0V. Despite being non-rechargeable batteries, they differ in size, voltage, capacity, and discharge characteristics.

Can I use AA batteries instead of LR44?

No, AA batteries are cylindrical batteries measuring 14.5 x 50.5 mm, whereas LR44 batteries are coin-shaped with dimensions of 11.6 x 5.4 mm.

What is the LR44 battery equivalent to?

LR44 batteries are equivalent to various types of 11.6 x 5.4 mm batteries, including alkaline, silver-oxide, and zinc-air batteries. While they share similar dimensions and voltages, their capacity and discharge characteristics may vary depending on the specific application.

Can the LR44 battery replace the hearing aid PR44/675 battery?

Yes, the LR44 battery can fit into the PR44/675 battery compartment in hearing aid devices. However, it’s important to note that LR44 batteries have significantly lower capacity (around 150 mAh) compared to PR44/675 batteries (around 650 mAh), resulting in shorter battery life.

Can I use AA batteries instead of LR44?

No, AA batteries cannot be used as a replacement for LR44 batteries. This is because AA batteries are larger cylindrical batteries measuring 14.5 x 50.5 mm, whereas LR44 batteries are smaller coin batteries with physical dimensions of 11.6 x 5.4 mm. The difference in size and shape means that they are not interchangeable and cannot be used interchangeably in devices that require LR44 batteries. It is important to use the correct type and size of battery as specified by the device manufacturer for optimal performance and safety.

Is LR44 the same as CR2032?

The LR44 battery and CR2032 battery are not the same. They differ in several key aspects. The LR44 battery is an alkaline coin cell battery with a voltage of 1.5V and specific dimensions, whereas the CR2032 battery is a lithium coin cell battery with a voltage of 3.0V and different dimensions. These differences in voltage, size, and other characteristics make the LR44 and CR2032 batteries distinct from each other.

What are some batteries similar to LR44/SR44/SR44SW that can replace button coin cells like CR11108 or CR1/3N, and what are their dimensions, voltage, and capacity ranges?

LR44/SR44/SR44SW batteries serve as suitable replacements for button coin cells such as CR11108 or CR1/3N.
