SR621SW vs. SR626SW Batteries
Overview of differences between the 2 types
The sr621sw battery has a voltage of 1.55 volts and a capacity of around 13 mAh, while the sr626sw battery has a voltage of 1.55 volts and a capacity of around 28 mAh. Additionally, the dimensions of the two batteries differ slightly, with the sr626sw being slightly larger than the sr621sw.
Effects on watch performance
A higher capacity battery like the sr626sw can provide longer-lasting power to the watch, allowing it to run for a longer period before needing a replacement. However, this increased capacity can also result in a slightly higher voltage output, which can potentially cause damage to the watch’s internal components over time.
On the other hand, the lower capacity of the sr621sw battery may result in a shorter lifespan, but it is less likely to cause any damage to the watch’s internal components due to its lower voltage output. Ultimately, the choice between the two batteries depends on the specific watch model and its power requirements.
It is important to note that while the sr626sw battery can technically be used as a replacement for the sr621sw battery in some watches, it is not always recommended. Using a battery with a higher capacity than what is specified by the manufacturer can potentially cause damage to the watch or void its warranty.
Equivalent Replacements for SR621SW Battery
Some compatible alternatives include batteries with similar specifications, such as the 364, AG1, or LR621 batteries. These alternatives share the same voltage and size as the sr621sw battery, making them suitable substitutes in many watch models. However, it is essential to consult the watch manufacturer’s guidelines or a professional watch technician to ensure compatibility before using these alternative batteries.
When selecting an equivalent replacement for the sr621sw battery, there are a few factors to consider.
- First, ensure that the replacement battery has the same voltage (1.55 volts) and dimensions as the original battery to ensure proper fit and function.
- Additionally, consider the brand reputation and quality of the replacement battery. Opting for reputable brands can help ensure reliable performance and longevity.
- Lastly, be mindful of any specific power requirements or recommendations provided by the watch manufacturer to ensure compatibility and avoid potential damage to the timepiece.
