CR2477 Battery Equivalents and Replacement
CR2477 batteries are specific in terms of size, voltage, and capacity, making it important to find the right equivalent when a direct replacement is not available. When looking for a CR2477 battery equivalent, the key factors to consider are the physical dimensions, voltage, and capacity of the battery. The equivalents may not match perfectly but should be close enough to function properly in most devices intended for CR2477 use.
LIR2477 Battery
CR2477 battery equivalent is also known as LiR2477, BR2477, DL2477, BR2477N, BR2477-1W, ECR2477, CR2477N, KCR2477, CR2450, CR2430, etc.
CR2450: While slightly thinner (5.0 mm height), the CR2450 has a similar diameter (24.5 mm) and voltage (3.0 V). The capacity is generally lower, which might affect the device's runtime.
CR2430: This battery is thinner (3.0 mm height) and has a slightly smaller diameter (24.5 mm) compared to the CR2477. It also operates at 3.0 V, but with a lower capacity, which could lead to shorter battery life in some devices.
CR2477N: The "N" version might indicate a slight variation in specifications, such as a narrower temperature range or different capacity. It's generally designed to be a direct replacement but check the specific device requirements.
DL2477: This is often a branding difference, with "DL" indicating a Duracell product. The dimensions, voltage, and capacity are typically intended to match CR2477 standards.
LiR2477: A rechargeable lithium-ion version with similar dimensions but requires a charger and careful usage due to its rechargeable nature.
BR2477: A lithium poly-carbon monofluoride version, offering different voltage characteristics and possibly longer shelf life in specific conditions.
