LR932 Button Cell Battery Selection and Replacement Guide

What the LR932 is

LR932 batteries are alkaline button cells with a nominal voltage of 1.5 volts. Their compact format makes them suitable for small handheld devices that require a stable low-voltage power source.

Some Berner Blue Opal handheld transmitters are identified as using this cell type. Because button batteries can appear similar across model families, buyers should confirm the specified model rather than rely on visual similarity alone.

Key specifications

Core information about the LR932 is summarized below.

Buying and replacement guidance

Purchasers should verify that the product is labeled LR932 and that it is supplied in unopened, unused original packaging. A reputable specialist battery supplier is preferable, and packaging integrity should be checked before purchase. Since batteries are chemical consumables, storage conditions can affect performance.

Batteries showing leakage, corrosion or deformation should not be used. Product information should provide clear storage conditions, and stock exposed to moisture or extreme temperatures should be avoided.

Compatibility and device checks

Battery model numbers generally denote specific dimensions and chemical characteristics. Similar-looking cells may not be interchangeable, so replacement should follow the model specified by the device manufacturer. If an alternative is considered, voltage and physical dimensions should match exactly to reduce the risk of device damage.

Handheld transmitters may show reduced transmission range, delayed response or abnormal indicator light behavior when power is low. Measuring the old battery's voltage can help confirm whether replacement is needed; a reading significantly below 1.5 volts would indicate that the cell should be replaced.
