LR43 vs LR44 Battery: Difference Between LR43 and LR44 Batteries
It's important to note that while LR43 and LR44 batteries share the same nominal voltage (1.5 volts) and may fit into the same compartment, they are not identical. The primary difference lies in their physical dimensions, with LR43 being 1.2mm thinner than LR44. Additionally, LR43 typically has a lower capacity (measured in mAh), which means it stores less energy than LR44.
- Fit in Battery Compartment
LR43 may physically fit into the LR44 battery compartment due to their similar diameter and voltage.
Ensure the batteries are inserted with the correct polarity, and they make good contact for reliable performance.
- Operational Duration
The lower capacity of LR43 implies that it stores less energy compared to LR44.
Your gadget may operate for a shorter duration when powered by LR43 compared to LR44.
If the device allows for the slightly larger size of LR44, using it may provide a longer operational time due to its higher capacity.
- Compatibility
LR43 may be suitable for devices that can accommodate the smaller size and lower capacity without affecting performance.
While LR43 and LR44 share some similarities, the choice between them should consider the specific requirements and compatibility of your device. If longer operational time is a priority, and the device allows for the slightly larger size, LR44 might be a more suitable choice.
Are LR43 and LR44 Batteries Interchangeable
Since LR43 and LR44 batteries differ in size, they cannot be used interchangeably. It's crucial to use the correct type of battery as recommended by the device manufacturer. Using the wrong battery size or type may result in improper functioning of the device, reduced performance, or even damage.
