(i.e., if it's the same "425", both CR425 and BR425 will basically fit) However, differences may occur depending on the float's specifications and usage environment. Difference between CR425 and BR425 There are two types of batteries used in fishing electric floats: CR425 and BR425. Both have basically the same external dimensions (diameter 4.0mm × length 25mm), but their internal chemical structures (material properties) differ, resulting in performance differences. BR is resistant to temperature changes (cold) and has a long lifespan. CR is said to have strong brightness and be cost-effective.
