Maxell deignates its battery as sr44w while Eveready designates its version as 357. Both have the same dimensions and both are 1.55v silver oxide cells. **Q: The headline says LR44, but the package shown does not. Is this a replacement for LR44 also ?** A: Yes, the SR44 can replace the LR44 and visa versa. The SR version is silver oxide which is more expensive, has higher power density, and is better for use in low drain, long battery life applications, such as digital calipers, watches and the like. The LR44 is an alkaline battery and is cheaper, so for high drain applications like small lights etc. where one expects to replace the battery more often, it often makes more sense to use the LR44. **Q: Are these Lithium batteries?** A: The 357/303 batteries are silver oxide. **Q: If I purchase multiple packs of these batteries, am I going to be hit with shipping for each one or will they combine?** A: Combine ## Frequently Bought Together - Energizer 357/303 Batteries (1 Pack), 1.5V Silver Oxide Button Cell Batteries - Energizer 357/303 Batteries (3 Pack), 1.5V Silver Oxide Button Cell Batteries - Duracell 2032 Lithium Battery. 4 Count Pack.
