LR43 VS LR44: Differences

• •The LR43 battery comes with the same voltage and diameter, and the LR44 has 1.2mm-thin features. If we use an LR43 battery for the LR44, it provides good working, and the device works well. But LR43 devices work for a shorter time than LR44 batteries.

Battery Compartment

• The LR43 battery can easily be put in the LR44 battery comparison since it has the same diameter and voltage value. Make sure that the battery is put in proper polarity and provides good working performance.

Working Duration

•  The low capacity of LR43 provides less energy storage than LR44 batteries. o devices using LR43 work shorter than LR44.

Compatibility

• The LR43 battery is best to use for small-size devices and where low capacity is easily handled without affecting performance.

Is LR43 like AG12?

• Yes, both are the same; the LR43 battery comes with different equivalent batteries, and AG12 is also its equivalent.
• The equivalent means that the AG12 batteries can eeasily be used as replacements for for LR43 batteries in different devices.
