Compare SR920SW With Other Models
SR920SW vs SR920W
The main difference between SR920SW and SR920W batteries lies in their shape. SR920W batteries are a variant of SR920SW, where the “W” stands for wide. The SR920W battery has a slightly larger diameter, making it suitable for devices with wider battery compartments. However, both batteries have the same voltage and capacity.
SR920SW vs SR927SW
SR920SW and SR927SW batteries have similar voltages and capacities. The primary distinction is their size. SR927SW batteries are slightly taller than SR920SW batteries, but they can still be used interchangeably in many devices. It’s essential to check your device’s specifications to determine which battery size is compatible.
SR920SW vs SR626SW
SR920SW and SR626SW batteries differ in terms of voltage and size. SR626SW batteries have a lower voltage of 1.55 volts and a smaller size compared to SR920SW batteries. While some devices may be compatible with both battery types, it’s crucial to consult the device’s manual or manufacturer to ensure the correct battery choice.
SR920SW vs 371
SR920SW and 371 batteries have different sizes and voltages. SR920SW batteries are 1.55-volt silver oxide batteries, while 371 batteries are 1.55-volt button cell alkaline batteries. They have distinct physical dimensions, so it’s important to use the battery type specified by the device’s manufacturer.
FAQs
How many volts is SR920SW?
SR920SW batteries are commonly known as 1.55-volt silver oxide batteries. They have a voltage of 1.55 volts, which is the standard for most small electronic devices.
What is the capacity of SR920SW?
