The CR1632 is a 3V lithium coin cell used in compact electronics. With a capacity of 120-150mAh and a shelf life of 10 years, it’s common in devices like key fobs, watches, and medical devices. Ensure to buy from trusted brands for reliability and long performance. Replace it when voltage drops below 2.5V.

The CR2430 is a 3V lithium coin cell with a 270-320mAh capacity, used in devices like watches and key fobs. It has a 10-year shelf life and operates in temperatures from -30°C to +60°C. Non-rechargeable, replace when voltage drops below 2.5V.

The AG13 is a 1.5V alkaline button cell with a 130-150 mAh capacity, used in small devices like watches and toys. Equivalent batteries include LR44, SR44 (silver oxide), A76, 357, and LR1154. Silver oxide batteries are better for high-drain devices. Always check compatibility before replacing.

The CR927 is a 3V lithium battery used in devices like watches and calculators. It has a capacity of 25-40mAh and dimensions of 9.5mm x 2.7mm. Equivalents include DL927, ECR927, and SR927SW. Ensure replacements match voltage and size. Store in cool, dry conditions for optimal lifespan.

The CR2 and CR123 are both 3V lithium batteries, but the CR2 is smaller (15.6mm x 27mm) with 800mAh capacity, suited for low-drain devices. The CR123 (17mm x 34.5mm) has a higher capacity (1500mAh), ideal for high-drain devices like flashlights. Though both have the same voltage, the CR123 lasts longer. They’re not interchangeable due to size differences.

The AG1 battery (LR621) is a small, non-rechargeable coin cell used in devices like watches and calculators. It comes in alkaline (shorter lifespan) and silver oxide (longer lifespan, stable voltage) versions. This guide compares both types, their equivalents, and offers troubleshooting tips. Silver oxide is best for precision devices, while alkaline is ideal for low-power applications.

The LR44 alkaline (1.5V) and 357 silver oxide (1.55V) button cells share the same size but differ in chemistry, capacity, and stability. This guide compares specs, lifespan, performance, interchangeability, and tips to choose the right battery for your device.

CR2450 is a 3V lithium coin cell (24.5×5.0 mm, 500–620 mAh). Equivalents include CR2450N, DL2450, BR2450, LM2450, and ECR2450. Always match size, voltage, and chemistry.
