Energizer 357 / 303 Watch Battery, Silver Oxide Multi-Drain. A size 357 battery is the equivalent of a SR44W battery. Both versions (SR44W and SR44SW) have the same voltage and same physical dimensions, it is perfectly safe to use the high drain version instead of the regular version. Over time, the watch industry has added new features such as background lighting or audible alarms to watches. And so, nearly all current watch batteries use silver oxide battery technology because that is most efficient when squeezing the last bit of electricity into a confined space for storage. Using regular battery in a high drain watch will, however, mean that you'll have to change the watch battery much earlier.

For powering your medical devices, calculators and watches reliably, use the Energizer 357/303 battery.
