These economical, single-use, alkaline, 1. 5 V button cell batteries, manufactured by a trustworthy well known name, are particularly useful for devices that may require high pulses such as laser pointers, digital thermometers and miniature flashlights. This is made possible by the cell's high capacity. They are suitable for many other applications including pen-lights, LED key fobs, calculators, watches and multi-meters. They can directly replace the following battery codes: V13GA, RW82, L1154, KA76, GPA76, GP76A, FM28F, AG-13, A76LR44, 1166A, V13GA, L1154, G13, AG13, 357, 303, 157 and LR154. These single-use, 1. 5 V, batteries make use of MnO2 (manganese dioxide) alkaline cell chemistry making them very economic. They have a nominal voltage of 1. 5V and a high capacity .
