Genuine factory-original FDK Sanyo CR14250SE 3-Volt lithium instrument cluster Service Interval (SI) board replacement batteries. This collection lot consists of a matching pair (2 individual pieces), brand new old stock (NOS) and hermetically factory-sealed inside clear protective distribution packaging sleeves.
These premium 1/2AA sized high-energy density cells utilize a specialized Lithium Manganese Dioxide (Li-MnO2) chemical composition engineered for exceptional terminal voltage preservation and leak-resistant storage stability. They are designed to be soldered directly to the interior dashboard circuit motherboard to power core cabin electronics, maintaining active indicator countdown lighting memories, clock retention data, and tachometer/econometer signal stability.
Important Installation Note: These 3.0V lithium batteries are explicit replacements for late-style (late 1985 and newer) electronics boards equipped with matching lithium hardware layouts. They cannot be used to replace older-style 1.2V NiCd AA-sized battery cells.
