10 x Eunicell AG4 Alkaline button cell batteries - G4 LR66 LR66SW LR626 LR626SW SR626W 376 377

Product Information

will show that all watch battery diameters in the 11mm range are 11.6 mm in diameter. Therefore, a L1154 is an The shelf life of watch batteries is determined by storage temperature and their chemistry. Typically, at 21 degrees

quite happily run a low drain watch using a high drain watch battery. ¨SW¨ batteries will tend to have a slightly The letters at the end of the reference number are different, one is W the other SW. Which one do you choose?

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. required. An Alkaline cell though is good for high current devices where a stable voltage is not required, for example, AG4 batteries have a chemistry that is alkaline and should not be used as a watch battery replacement or a hearing aid battery replacement. The alkaline AG4 will not have enough capacity or continuous voltage to power these devices. An alkaline batteries voltage will slowly drop over time. It is imperative that the correct chemistry battery is used for the right application. In the Silver Oxide range of batteries you will often see a different suffix to the same battery reference. For example

refers to high drain devices. So what's the difference? Well you would tend to only use a ¨SW¨ battery wherever you see a three or four digit reference number for a watch battery it is likely to follow the rule described above. Therefore, the voltage of your application will dictate whether you will need a Lithium battery or not. The Lithium cells Note, that the lithium watch batteries, or button cells, are 3 volts, not 1.5 volts and cannot be substituted for a 1.5 volt silver oxide watch battery or alkaline available. There is a much wider choice of Silver Oxide watch battery sizes. In fact Rayovac make only two Alkaline button

The SR626SW watch battery is also known as the 377 battery, SR66, SR626 or AG4 battery. The SR626SW or 377 watch battery is one of the most widely used watch batteries. Available singly or in packs of 10 batteries for the price of 8.

so here's a short list. Manufacturers who use SR to denote a Silver Oxide watch battery will tend to use Other manufacturers, like Rayovac, number their batteries without giving a clue as to the size of the watch battery, provide this information if you like, but you don't need to know this if you are replacing a watch battery in household

this is a lithium battery. The handbook is wrong! The replacement for the National GR927 is the 399 silver oxide battery and notand absolutlely essential for metering equipment (like light meters in cameras for example) where a stable voltage is longer life when used in low drain devices than their ¨W¨ equivalent. If in doubt use the high drain ¨W¨ which had a capacity given as 40mAh will be able to supply 40 milliamps for an hour or 20 milliamps for two hours. We can gizmos. Really it's for the electronic buffs who need to know which battery to use in a newly designed circuit.

cell sizes but approximately 30 different Silver Oxide watch battery sizes. Where Silver Oxide cells score over their Alkaline in suggesting to owners of the Thunderbird Soundtech toys (which use 3 x LR41) that they can use the Silver Oxide

SR621SW vs SR626SW Battery

Well, firstly Silver Oxide watch batteries tend to be more expensive than an Alkaline cell of the same size. So can you Mercury watch batteries are no longer manufactured so your only alternative is to use a silver oxide watch battery of the same size. You should For further information about watch batteries; their chemistry, numbering, watch battery prefixes and the CR927 3V lithium battery. This mistake in the handbook appears across several different models of Casio solar calculators. 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
