When it comes to button or coin batteries, there is a plethora of options that you can explore.
Like other batteries, you probably looking for the reliability, performance among many other features.
And this is where SR621SW battery comes in.
What is it and how do you rate it in terms of performance?
This is a perfect guide for you.
In case you have been planning to buy SR621SW battery in bulk or for a specific application area, we are going to give you all the information that you will need.
Including on how to choose the best SR621SW battery supplier in China.
Overview of SR621SW battery
A brief out look. What is SR621SW battery?
This is more than your ordinary button cell battery.
It is a non-rechargeable button cell battery that is used in a wide range of applications.
The SR stands for the Silver-Oxide. This is the basic chemical composition of this battery.
It has been combined in a way that it is capable of delivering sufficient energy to the different devices that wholly rely on it.
Keep in kind that silver-oxide is an alkali, so, we can confidently state that these batteries are alkali in nature.
You can easily find the SR621SW batteries in calculators, medical devices,film cameras, among many other devices.
Who are the makers of SR621SW batteries?
A brief history, SR621SW battery traces its roots to the Seiko Instruments Inc (SII) Seiko was established by the Seiko Group to focus on manufacturing their watches. And this explains why these batteries were originally used on the timepieces.
Seiko Instruments Inc supplies micro mechatronics devices such as watch, semiconductors, network solutions, scientific instruments, HDD components among many other devices.
From the examples, it is clear that the company has a specialty on the low-drain devices.
Equipped with vast resources and machinery, Seiko has all that it takes to manufacture quality SR621SW batteries for sale.
They also have an expansive network of suppliers who ensure that the battery reaches the target customers.
For example, there are many SR621SW suppliers and distributors in China. All you need is to choose the right one and place your order for the battery.
Features of SR621SW battery
Now let’s look at the key features associated with SR621SW battery.
Low drain battery
We can comfortably categorize the SR621SW as a low-drain battery.
As the name suggests,it drains the power at low rate.
So, it is an ideal battery option for the devices that require power over a significantly longer period. For example, a timepiece.
Low drain batteries are completely different from the high-drain batteries. The main difference being the fact that even though high drain batteries may have low power consumption, they tend to have high peaks. This means that there are moments when there power consumption is significantly high.
Chemical composition: Silver oxide
As e have already mentioned, the SR621SW battery is silver oxide. This chemical makeup makes it to be a fully alkali battery.
Compact and lightweight
When it comes to the physical dimensions, this is a button-cell battery. It measures 0.27Dia x 0.08 H 6.8mmx2.0mm.
For the weight, it is approximately 0.32g.
These dimensions keep it in the competition among the many button cell batteries in the market.
Also, the compact size ensures it fits in different devices perfectly without the requirement of any modification.
Power specifications
So, how does SR621SW perform? Like other batteries, it all depends of the power features and specifications.
The battery has a rated voltage of 1.5: Just like most batteries in this category.
It has the current capacity of 23mAH
SR621SW battery has a discharge rate of 40µA, a feature that makes it fall under the low-drain current.
Its operating temperature is between -10ºC and +60ºC. This range makes the battery suitable for different environment.
From these features and technical specs it is clear that SR621SW is a performance-oriented and reliable button cell battery.
However, when buying it is vital to verify that these are the correct features. Buying directly from a reliable supplier is the surest way of verifying the specs.
A brand new SR621SW should meet all the specs that we have outlined here. Otherwise, a used one one is likely to have degraded and wont deliver the performance that you desire.
Applications of SR621SW Battery
SR621SW batteries have a wide range of applications. They include:
-TV remote controls
-Timepieces
-Alarm clocks
-Cameras and video recorders
-Electronic gaming devices
-Medical instruments and devices
-Calculators
-Among many others.
Are you building a device whose specifications requires int to be powered by a 1.5V? Then you should consider getting this battery.
How to protect SR621SW battery
After buying your SR621SW batteries, you would definitely want to get the best results from them.
A well-protected battery will serve you for long and as well guarantee safety of your device.
Here are the best tips for protecting SR621SW.
-Do not short-circuit between the terminals. SR621SW has well labeled + and – terminals. Avoid shorting it when handling.
-Keep the battery within the recommended temperature range. This will preserve the chemical composition and effectiveness.
-Do not keep the battery near fire and flame
-When it comes to discharging, ensure that the SR621SW battery is off the device and is connected to the ground.
SR621SW Equivalents
Most SR621SW alternatives are the alkali button cell batteries. They include
-SR60
-280–34
-D364
-SB-DG
-TR621SW
Most of the above listed batteries are similar to the SR621SW in terms of the physical dimensions and the power requirements.
To be safe, ensure that the device can accept the alternative battery before you proceed to install.
Also, it will be wise to confirm with the device’s manufacturers.
Buying SR621SW battery
