Lithium batteries.
Silver-oxide is the most common type of watch battery that runs on a voltage of 1.55 volts, slightly higher than Alkaline. These batteries are meant to last up to 10 years. Lithium batteries are the highest quality and the most expensive.
What kind of batteries are used in a watch?
About Watch Batteries. Most batteries used in watches today are silver-oxide or lithium batteries, of which there are over 100 in use. The shelf life of a battery is the same as its useful life.
Do all watches use same battery?
All watch batteries are not the same. We have 2 basic types, 1.55 volt silver oxide batteries and 3.0 volt lithium batteries.A watch movement takes a specific size and type of battery and they cannot be interchanged. Most of the time we can only tell what battery your watch needs by taking off the back of the watch.
What size is a standard watch battery?
5 to 25 mm
A button cell, watch battery, or coin battery is a small single-cell battery shaped as a squat cylinder typically 5 to 25 mm (0.197 to 0.984 in) in diameter and 1 to 6 mm (0.039 to 0.236 in) high resembling a button.
What battery is equivalent to 377?
SR626SW
377 Watch Battery SR626SW and equivalent button cell batteries – SR626, SR626W, SR66, D377, V377, AG4, GP377, SB-AW, 377.
What size battery does my watch take?
Step 1: Find the battery code: In order to identify the correct replacement battery for your watch you will need to know the battery code. Sometimes this is printed on the back of the watch – as with some Timex watches – but in many cases you will need to open your watch case to see the code on the battery.
What is the difference between 370 and 371 battery?
Whilst the 370 and 371 are the same physical size, the 370 is designed for high drain applications (watches with alarms and chronographs etc), the 371 is for low drain. You can use either but if you use the wrong one for your watch the battery life will be shorter.
What battery is equivalent to CR1216?
BR1216 battery
CR1216 can be replaced with a BR1216 battery (non-rechargeable carbon-monofluoride lithium battery) which features a slightly lower (on average 2.8 vs 3.0 volts), but more stable voltage during the use, and lower discharge current – hence, the BR1216 battery should NOT be used with watches that feature an alarm, LED
Are AG12 and AG13 batteries the same?
Both are 11.6mm diameter. AG12 (LR43) is 4.2mm thick. AG13 (LR44) is 5.4mm thick.AG12 = 55 mAh, AG13 is 60 mAh.
What is the difference between LR and SR batteries?
LR44 and SR44 are the same physical size. However, the terminal voltage of the SR version is a tad higher (1.55v -v- 1.5v) and its capacity is also higher. There are plenty of devices around that are designed to work with the LR44 battery.
What battery can replace CR2032?
CR2025 battery
The CR2025 battery is an extremely common lithium coin cell battery and is used in similar amounts and in similar applications as the CR2032. The CR2025 is slightly better suited for use in products that have less available mounting space than those that would use a CR2032.
Are 177 and 377 batteries the same?
– Silver-oxide SR626/SR626SW batteries have a nominal voltage of 1.55 volts and it is rather constant over time as the battery is drained.

| Chemistry | Alkaline | Silver-Oxide |
|---|---|---|
| Typical Labels | LR66, LR626, AG4 | 177, 376, 377, AG4, SG4, SR66, SR626, SR626SW |
Are watch batteries 626 and 377 the same?
377 button battery replaces SR626W and SR626SW batteries. The Energizer 377/376 is a multi-drain 1.55 Volt silver oxide button cell battery. Primarily used as watch batteries, 377 376 replaces SR626W and SR626SW batteries.
What battery can replace 362?
SR721SW
362 Watch Battery SR721SW and equivalent button cell batteries – SR721SW, sR58, SR721, SB-AK, 280-29, S ,V362, D362, S721E, AG11 GP362.
Are 377 and 379 batteries the same?
As for the size difference between 379 and 377, 379 is 5.80mm x 2.15mm and 377 is 6.80mm x 2.60mm, so 379 is both smaller diameter and thinner.
What is a 364 battery?
Silver Oxide Button Battery: Duracell’s 364 Silver Oxide Button batteries provide reliable, long lasting power for your medical devices, watches, toys, electronics and more.#1 Trusted Battery Brand: This Duracell 364 Silver Oxide Button Battery is equivalent to SR60, D364, SP364, SR621W, V364, 364, SR621, SR621SW.
What is the smallest battery for a watch?
Among the smallest of the watch batteries, the 392 button cell has a wide range of uses.
What battery is equivalent to a 370?
Battery SR920W
370 Watch Battery SR920W and equivalent button cell batteries – SR920W, ST69, SR921, SB-BN, 280-51, V370, GP370, 620, S921E.
What is the difference between W and SW battery?
In the IEC ‘standard’ battery designation convention, the low drain or normal version of the watch battery will end with the letter ‘W’, while the high drain version would end in ‘SW’. A common watch battery is the SR44W (or the SR44SW for the high drain version).
Are 376 and 377 watch batteries interchangeable?
Interchangeable batteries.
Now some watch batteries are interchangeable.If your watch takes either of these cells, you can use 376 or 377 in your watch. It doesn’t matter. Either one will work (good to know if the store is out of one number and not the other).
Are CR1220 and CR1216 the same?
CR1216, CR1220, and CR1225 batteries are very similar batteries, with the main difference being is size and thus their features and performances: – BR1216/CR1216 batteries feature physical dimensions of 12.5 x 1.6 mm, the smallest capacity (~25 mAh), and the drain currents very similar to the BR1220/CR1220 batteries.
