Button Cells

Very small button cell commonly used in watches and miniature electronics. Available in both alkaline (AG1/LR621) and silver oxide (364/SR621SW) chemistries. Silver oxide provides more stable voltage.

Small button cell commonly used in watches and precision instruments. Available in both alkaline (AG3/LR736) and silver oxide (392/SR736SW) chemistries.

One of the thinnest coin cell batteries available, designed for applications where space is extremely limited. The small size severely limits capacity and current capability, making it suitable only for ultra-low power applications like watch circuits and memory backup.

High-capacity cylindrical lithium battery. Popular in professional photography and high-drain devices. Also known as 123A, CR123, DL123A, K123LA.

Ultra-thin lithium coin cell commonly used in key fobs and compact electronics. Very thin profile at only 1.6mm height.

Popular lithium coin cell with good capacity for its size. Commonly used as CMOS battery in computers and various electronic devices.

Popular in photography equipment due to excellent pulse current capability and voltage stability. Essentially two lithium cells in series, providing 3V output with high capacity. Preferred over AA batteries in cameras for better performance and longer life.

Thinnest variant of CR20xx series with lowest capacity. Same diameter (20mm) but only 1.6mm thick. Used in ultra-thin devices like slim watches.

Thinner variant of CR2032 with reduced capacity. Same diameter (20mm) but only 2.5mm thick. Lower capacity than CR2032 but fits in tighter spaces.

Most common coin cell battery. Excellent shelf life and temperature stability. Used in applications requiring long-term, low-current power. In microamp applications, can last over 10 years.

Medium-capacity lithium coin cell with good current handling for automotive and wireless applications. Popular in key fobs and remote controls.

High-capacity coin cell designed for applications requiring longer runtime or higher current draw than standard CR2032. The larger size provides approximately 3x the capacity of CR2032. Popular in devices with LCD displays or periodic high-current pulses.

Compact lithium coin cell for low-power applications. Less common than CR2032 but used in specialized small electronics.

One of the most confusing battery types due to multiple equivalent designations. LR1154, LR44, and AG13 are all the same alkaline battery. Silver oxide versions (357, 303, SR44) offer better performance but cost more.

Small alkaline button cell commonly used in digital thermometers and basic electronic devices. More economical than silver oxide equivalents but with less stable voltage output. The AG3 designation is widely recognized in consumer markets. Not recommended for precision timing applications where silver oxide SR41 would be superior.

Small alkaline button cell battery. Also known as AG13, A76, 357, SR44. Common in small electronics and toys.

One of the most common button battery sizes with both silver oxide (SR44) and alkaline (LR44) chemistry options. Silver oxide provides superior performance with stable voltage and higher capacity, while alkaline offers lower cost. The flat voltage profile of silver oxide makes it preferred for precision devices.

High-quality silver oxide button cell optimized for precision timing applications like watches. Provides very stable 1.55V output with flat discharge curve, making it superior to alkaline equivalents for timing-critical devices. The 'SW' designation indicates it's suitable for watch applications requiring stable voltage.
