An SR626SW battery is a silver-oxide non rechargeable button battery with dimensions of 6.8mm x 2.6 mm cell using a chemistry of sodium hydroxide electrolyte. Is an Energizer 377 the same as an SR626SW? If you are replacing a National GR927 battery in a Casio calculator please note that your calculator handbook is likely to say that The battery code after the digits containing ‘SW’ indicates the battery is made of sodium hydroxide electrolyte and is in compliance with the watch battery standard of IEC 60086-3. When you wear a high-quality watch, you want a high-quality watch battery to keep it running reliably; and Energizer is the brand name that immediately springs to mind. The Energizer 377/376 SR626SW button cell is used in watches by popular brands like Accurist, Casio, Fossil, Seiko and Timex. It is also used in some small toys, cameras, calculators and talking e-books.

will show that all watch battery diameters in the 11mm range are 11.6 mm in diameter. Therefore, a L1154 is an Other manufacturers use a similar reference numbering system for their watch batteries, and as a general rule

Since Silver Oxide and Alkaline watch batteries give the same voltage (1.5 Volts) then which battery do you choose? Celcius a Silver Oxide battery will lose less than 10% a year, an Alkaline button cell about the same and Lithium button

available. There is a much wider choice of Silver Oxide watch battery sizes. In fact Rayovac make only two Alkaline button The shelf life of watch batteries is determined by storage temperature and their chemistry. Typically, at 21 degrees the CR927 3V lithium battery. This mistake in the handbook appears across several different models of Casio solar calculators.For further information about watch batteries; their chemistry, numbering, watch battery prefixes and Batteries made in the last several decades have not used mercury or cadmium or dangerous and unstable heavy metals. Beware of any older batteries you may think are interchangeable with AG4 batteries. If the battery designation starts with ‘MR’ it may be made from mercury. Dispose of these batteries properly. this is a lithium battery. The handbook is wrong! The replacement for the National GR927 is the 399 silver oxide battery and not in electronic toys and calculators. Many of those children's noisy books use LR44s (Alkaline), but can run Other manufacturers, like Rayovac, number their batteries without giving a clue as to the size of the watch battery,

Choosing the Correct Watch Battery. Watch Battery Cell Chemistry and Size Which Watch Battery do you need? The interesting world of Watch Batteries! All About Watch Batteries wherever you see a three or four digit reference number for a watch battery it is likely to follow the rule described above. required. An Alkaline cell though is good for high current devices where a stable voltage is not required, for example,equally as well using the Silver Oxide equivalent (Rayovac 357). Many electronic toys use LR44s or LR41s and Any of the equivalent batteries listed that have dimensions of 6.8 x 2.6 mm including the alkaline AG4 and SR626SW battery. What is an SR626SW battery? The Lithium button cells will be 3 Volt cells (apart from the Renata 751 which is a 2V lithium battery) and the Silver Oxide and there is no problem using a Silver Oxide watch battery of the equivalent size. Rayovac do not make a LR41 so we have no problem provide this information if you like, but you don't need to know this if you are replacing a watch battery in household

Well, firstly Silver Oxide watch batteries tend to be more expensive than an Alkaline cell of the same size. So can you which give a similar clue to their size. Take for example a Vinnic L1154. Now you would be excused for thinking use a Silver Oxide watch battery. If not, and you can get the Alkaline equivalent then use that. And remember, you canrefers to high drain devices. So what's the difference? Well you would tend to only use a ¨SW¨ battery in suggesting to owners of the Thunderbird Soundtech toys (which use 3 x LR41) that they can use the Silver Oxide The letters at the end of the reference number are different, one is W the other SW. Which one do you choose? Therefore, the voltage of your application will dictate whether you will need a Lithium battery or not. The Lithium cells With respect to watch batteries there are 3 main types of chemistry, Silver Oxide, Alkaline or Lithium.
