-
Battery Size:
The battery size of a 675 battery is larger than that of an LR44. The dimensions of a 675 battery are typically 11.6 mm in diameter and 5.4 mm in height, while an LR44 battery generally measures about 11.6 mm in diameter and 5.4 mm in height as well. However, the 675 is sometimes considered bulkier in applications due to its design for specific devices, like hearing aids. -
Voltage:
The voltage of batteries varies between the two types. A 675 battery generally has a nominal voltage of about 1.4 volts, while an LR44 battery usually has a voltage of 1.5 volts. While this difference may seem minor, it can significantly impact device performance, particularly in devices sensitive to voltage fluctuations. -
Applications:
The applications of these batteries differ notably. 675 batteries are predominantly used in hearing aids, which require consistent and reliable power for sound amplification. In contrast, LR44 batteries are widely utilized in small electronics, such as watches, calculators, and toys, where more versatile power solutions are needed. -
Chemistry:
The chemistry behind the batteries also differs. 675 batteries utilize zinc-air technology, which relies on the chemical reaction between zinc and oxygen. This results in a high energy density and is suitable for hearing aids. On the other hand, LR44 batteries typically use alkaline or silver oxide chemistry. Alkaline batteries are more common in consumer electronics, while silver oxide batteries provide longer-lasting power for devices that require steady energy over extended periods. -
Shape:
The shape of the batteries plays a role in their application. Both 675 and LR44 batteries are round, but they are designed for different devices. The flat design of the 675 makes it suitable for slim electronics like hearing aids, while the more standard cylindrical LR44 is adaptable to a wide range of devices.
Understanding these differences is crucial when selecting the appropriate battery for specific needs and ensuring compatible power options for devices.
Can a 675 Battery Function in Devices Designed for LR44?
No, a 675 battery cannot function in devices designed for LR44. They are not interchangeable due to differences in size and voltage.
The LR44 battery is an alkaline button cell battery, typically measuring 11.6 mm in diameter and 5.4 mm in height. In contrast, the 675 battery is a zinc-air battery, primarily used in hearing aids. The 675 battery has a larger diameter and different voltage characteristics, making it unsuitable for devices that specifically require LR44 batteries. This incompatibility means devices designed for LR44 will either not function properly or may be damaged if a 675 battery is used.
Are There Risks When Using a 675 Battery Instead of an LR44?
No, there are risks when using a 675 battery instead of an LR44. The two batteries differ in their size and voltage specifications. Using a 675 battery may lead to improper fitting, performance issues, or potential damage to the device.
The LR44 battery is a commonly used alkaline button cell battery, typically measuring 11.6 mm in diameter and 5.4 mm in height. It has a voltage of 1.5 volts. In contrast, the 675 battery is a zinc-air battery, primarily used in hearing aids, measuring 11.6 mm in diameter but having a different height of 5.4 mm. While both batteries share similar dimensions, they have different chemistries and discharge characteristics, making them unsuitable substitutes for one another.
One benefit of the 675 battery is its superior energy density, providing a longer lifespan for devices designed specifically to use it. In hearing aids, for example, the 675 battery can last significantly longer than alkaline batteries, with some users reporting up to a week of continuous use. This longer duration is particularly valuable for individuals relying on these devices daily.
On the downside, using a 675 battery in place of an LR44 can lead to several problems. The voltage output of a zinc-air battery may create excessive power which can damage sensitive electronic circuits designed for the LR44. Also, zinc-air batteries require a certain amount of air exposure to function properly. In closed devices, this exposure might lead to performance failures or leakage.
When choosing between a 675 battery and an LR44, it’s essential to use the battery specified by the device’s manufacturer. For users who own hearing aids, using the designated 675 battery is advisable for optimal performance. For devices that require LR44 batteries, always replace them with the same type to avoid complications and ensure proper functionality.
