Product Overview
Energizer 2450 Lithium Coin Batteries are three-volt specialty batteries designed for small electronic devices requiring the CR2450 cell size. This retail configuration contains two batteries and uses child-resistant packaging intended to reduce access to loose coin cells. Model 2450BP-2N is compatible with devices specifically designed for 2450-size lithium coin batteries and may replace designated equivalents such as DL2450, L52, and 5029LC when the device manufacturer permits those substitutions.
The batteries use lithium coin-cell chemistry and are intended for applications such as keyless-entry remotes, heart-rate monitors, small electronic controls, toys, and other specialty devices. Energizer specifies operation across a broad temperature range, though actual service life depends on device current draw, storage conditions, temperature, and usage patterns. Coin batteries present a serious ingestion hazard and must be kept away from children. Used cells should be removed promptly and disposed of according to applicable local requirements. They must not be recharged, crushed, disassembled, heated excessively, or exposed to fire. This exact two-pack configuration is identified by model 2450BP-2N and UPC 039800137449.
