AG10 / LR54 1.5V Alkaline Button Cell Battery | Pro Tronix

Product Description

The AG10 (also widely cross-referenced as LR54, 389, or LR1130) is a high-efficiency alkaline button cell battery specifically optimized to provide long-lasting, reliable 1.5V power to sub-miniature and low-drain electronic devices. Engineered for consistent voltage stability, this primary cell minimizes voltage drop-offs to protect sensitive electronic circuits. Its compact structure features an advanced anti-leakage seal, ensuring a stable shelf life and exceptional safety during prolonged device deployment. For technicians, lab operators, and electronics hobbyists, it represents a highly cost-effective and dependable choice for keeping compact instrumentation continuously powered.

Pinout / Layout Connections

The battery’s metal casing is segmented to serve directly as its electrical contact terminals:

• Top Face & Wide Outer Rim (+): The flat polished upper face stamped with the model designation acts as the positive terminal.

• Bottom Circular Face (-): The slightly raised, circular surface on the lower base serves as the negative terminal.

• Insulation Gasket: A micro-thin plastic isolation ring separates the outer positive shell from the negative floor to protect the cell from self-discharging or short-circuiting inside tightly fitted standard battery slots.

Applications

• Precision Instruments: Miniature digital calipers, pocket scales, and digital thermometer probes.

• Medical Equipment: Compact clinical instruments, penlights, and digital diagnostic tools.

• Office & Gadgets: Small pocket calculators, laser pointers, and compact digital travel clocks.

• Consumer Goods: Interactive children’s books, electronic toys, and LED novelty keychains.

• Wearables & Novelties: Specialized digital wristwatches and low-power novelty miniature devices.
