Battery LR44 A76 Used in Watches, Calculator, Electronics and more High Quality Battery 10 On A Pack About LR44 LR44 is an alkaline 1.5 V battery. The most common equivalent batteries are: AG13 L1154 LR1154 157 Silver Oxide Equivalent Batteries LR44 can be also be replaced with a silver oxide battery. The most common silver oxide equivalents are: SR44 SR44SW 303 357 Label Confusion Many generic packages will list both AG13 and 357 on the label, which are different battery chemistries. Generally, if it lists any alkaline name, then the batteries are alkaline and not silver oxide. Comparing Equivalent Batteries in Detail So now you know the equivalent names. Even though the size is the same, they may not be exactly alike. Prices can range among equivalent batteries and knowing how to compare specifications will make you better informed for choosing one. These days, brand name batteries are mainly selling silver oxide equivalents. So if you are buying from a big box retailer, you will only probably find 357 or 303 Energizer or Duracell batteries. But with the price of silver going up, they are getting more expensive all the time. Alkaline LR44 batteries are cheaper, but which one should you use? Alkaline Equivalent Cheap Voltage decreases with battery life Shorter life Silver Oxide Equivalent Expensive Maintains voltage with use Longer life As you can see, the main differences are the price, life, and voltage. So if you are just using the battery for some toys, blinking lights, or a calculator, an alkaline might suit you better. Some electronics which require a certain voltage to operate such as a digital caliper, will fare better with a silver oxide battery. Compare the following voltage discharge graphs. You can see silver oxide equivalent batteries maintain a higher voltage longer. This is why devices that require a certain voltage to operate will seem to eat up alkaline batteries because at 50% capacity, the alkaline battery will not have enough voltage to operate the device.
