This DSLRKIT AA/LR6 to CR2032 Dummy Battery Adapter is designed to replace traditional CR2032 coin cells in fixed-mounted devices, allowing you to achieve significantly extended runtime without frequent battery replacement. It is ideal for wall-mounted thermometers, wireless buttons, remote switches, smart sensors, and other devices that originally use CR2032 batteries.

The adapter case holds two AA/LR6 batteries and includes an ON/OFF power switch, making it convenient to control power when the device is not in use. The ultra-thin Flexible Flat Cable (FFC) allows installation without modifying or carving extra cable space inside the device.

The CR2032 dummy cell is built from real CR2032 casing, maintaining original curvature, thickness, and edge size. It fits securely in battery compartments where many low-quality aftermarket dummy batteries fail due to flat edges or welded wires.

Note 1：Multiple dummy cells can be connected in series or parallel, but only among this product type. Do not mix with other dummy battery styles to avoid voltage mismatch or physical incompatibility.

For best performance, it is recommended to use standard 1.5V AA alkaline batteries or lithium AA batteries.

Note 2：When using 1.2V Ni-MH rechargeable AA batteries, some devices that are sensitive to voltage may experience shorter runtime due to lower working voltage.
