Compact 12V power source consisting of eight LR932 alkaline cells connected in series. Despite small size, provides reliable high-voltage power for remote controls and security devices. Voltage remains relatively stable during discharge, making it suitable for devices requiring consistent 12V operation.

Compact 6V power source created by stacking four LR44/SR44 cells in series. Despite small size, provides reliable power for electronic devices requiring 6V operation. Silver oxide versions offer more stable voltage discharge curve and higher capacity than alkaline.

Rectangular battery with distinctive snap terminals. Contains multiple smaller cells internally. Despite name, fresh voltage is typically 9.6V for alkaline. IEC designation 6F22 for carbon-zinc, 6LR61 for alkaline.

AAA-sized lithium-ion. Much higher voltage than AAA alkaline - verify compatibility. Name comes from dimensions: 10mm diameter × 44mm height. Direct AAA size replacement but with 3.7V instead of 1.5V.

Compact lithium-ion cell roughly 2/3 the length of a 14500 (AA-sized) battery. Popular in applications where space is extremely limited but AA batteries don't provide sufficient voltage. Less common than other formats, so availability and quality can vary significantly between manufacturers.

AA-sized lithium-ion. Higher voltage than AA alkaline - check device compatibility. Name comes from dimensions: 14mm diameter × 50mm height. Direct AA size replacement but with 3.7V instead of 1.5V.

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-performance lithium battery designed for camera applications requiring 6V power. Essentially two CR123A cells in series in a single package. Excellent for high-drain camera applications including autofocus and flash charging.

Compact 6V battery consisting of four LR44 cells in series. Common in vintage cameras and specialized electronic devices. Available in both alkaline and higher-performance silver oxide chemistries. Often called 'dog collar battery' due to popular use in pet training devices.

Professional 6V lithium camera battery. Rectangular form factor designed specifically for camera applications. Excellent high-drain performance and cold weather operation. Essential for many vintage and professional film cameras requiring 6V power.

Smallest hearing aid battery. Zinc-air chemistry provides stable voltage and high energy density. Air-activated system requires removal of sealing tab. Color-coded yellow for easy identification.

Most popular hearing aid battery size. Zinc-air chemistry provides stable voltage and high energy density. Air-activated system requires removal of sealing tab. Color-coded orange for easy identification. Excellent balance of size, capacity, and runtime.

Mid-size hearing aid battery. Zinc-air chemistry provides stable voltage and high energy density. Air-activated system requires removal of sealing tab. Color-coded brown for easy identification. Good balance of size and capacity.
