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. and absolutlely essential for metering equipment (like light meters in cameras for example) where a stable voltage is

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 alkalinewherever you see a three or four digit reference number for a watch battery it is likely to follow the rule described above.

Yes, an Energizer 377 or 376 battery is a silver oxide battery measuring 6.8mm x 2.6 mm. It is equivalent to a SR626SW battery. What does SW mean on a 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 Batterieswill show that all watch battery diameters in the 11mm range are 11.6 mm in diameter. Therefore, a L1154 is an In the Silver Oxide range of batteries you will often see a different suffix to the same battery reference. For example

The letters at the end of the reference number are different, one is W the other SW. Which one do you choose? Just a few words on battery capacity. This tends to be given by the manufacturers in mAh (milli Amp hours) Since Silver Oxide and Alkaline watch batteries give the same voltage (1.5 Volts) then which battery do you choose? equally as well using the Silver Oxide equivalent (Rayovac 357). Many electronic toys use LR44s or LR41s and

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.

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. the CR927 3V lithium battery. This mistake in the handbook appears across several different models of Casio solar calculators. 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 Well, firstly Silver Oxide watch batteries tend to be more expensive than an Alkaline cell of the same size. So can you For further information about watch batteries; their chemistry, numbering, watch battery prefixes and

required. An Alkaline cell though is good for high current devices where a stable voltage is not required, for example, in electronic toys and calculators. Many of those children's noisy books use LR44s (Alkaline), but can runWhen 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. which give a similar clue to their size. Take for example a Vinnic L1154. Now you would be excused for thinking Now having had this lesson, you will begin to see that other watch batteries also have a reference number
