The Complete Guide For D-Shaped Battery

When choosing a battery for your device, factors such as size, energy output, and reliability are critical considerations. One type of battery that has gained popularity across various industries is the D-shaped rechargeable lithium polymer (LiPo) battery. Specifically, the 503533 D-shaped battery by Ufine Battery offers excellent performance in a compact form, perfect for wearable devices, medical equipment, GPS systems, Bluetooth devices, and more. 

Part 1. Conventional Circular Battery Types

Circular batteries have long been the go-to option for devices requiring compact and reliable power sources. These small round batteries come in various chemistries and sizes, with lithium polymer (LiPo) and lithium-ion being the most common for high-energy applications. Circular batteries are commonly used in wearable technology, hearing aids, smartwatches, fitness trackers, and wireless earphones due to their small footprint and efficient energy storage.

Although circular batteries are popular, their shapes are not always ideal for every device. This is where shaped batteries, such as the D-shape battery, offer an advantage. The 503533 D-shaped rechargeable LiPo battery by Ufine Battery brings the benefits of a small round battery with the added advantage of a more versatile design that fits well in a variety of devices.

Part 2. D-Shaped Battery: Size and Lightness

One of the standout features of the 503533 D-shaped battery is its compact D-shape design, which is highly suited for devices that require a power source that doesn’t take up too much space but can still provide substantial energy output. At 5.0mm thickness, 35mm width, and 33mm length, this battery is perfect for devices like smartwatches, wearable medical devices, and Bluetooth accessories. Its size ensures that your device maintains a sleek profile without sacrificing performance.

At just 9 grams, this battery is lightweight, making it ideal for wearables and portable gadgets where weight is a concern. Whether you’re designing a fitness tracker or a wireless earbud, the D-shape battery is an excellent choice when you need a compact and lightweight power solution.

Part 3. Advantages of Rechargeable Lithium Polymer Batteries

Lithium polymer batteries come with several distinct advantages over other types of rechargeable batteries. One of the primary benefits is their lightweight nature, which is crucial for portable and wearable devices. Additionally, lithium polymer batteries can be shaped and molded to fit specific designs, allowing for flexibility in product development.

The 503533 D-shaped battery offers a nominal voltage of 3.7V and a capacity of 500mAh, ensuring reliable and long-lasting power. The battery’s charging voltage is 4.2V, and it supports charging currents of 0.5C to 1C, making it efficient for use in small devices that require consistent energy over time. Furthermore, the 300 cycle life guarantees a long service life, meaning the battery can be recharged many times without a significant loss in performance.

Part 5. How Long Can a 503533 Circular D-Shaped Battery Run?

The 503533 D-shaped LiPo battery provides excellent energy efficiency, and the 500mAh capacity makes it ideal for small devices. To estimate how long this battery can run, let’s look at some examples:

Smartwatch: A typical smartwatch draws about 100mA of current when in active mode. Using the formula for runtime, we can calculate the approximate duration:

Runtime (hours)=Capacity (mAh)/Current (mA)=500mAh/100mA=5hours

This means a 503533 D-shaped battery would power a smartwatch for around 5 hours of continuous use.

Bluetooth Earbuds: Wireless earbuds typically use about 50mA of current while operating.

Runtime (hours)=500mAh/50mA=10hours

In this case, the battery would provide approximately 10 hours of use.

If your device demands a longer runtime, Ufine Battery offers the option to customize the battery’s capacity to meet your needs. We can increase the capacity to deliver more energy, ensuring your device stays powered for extended periods.

Part 6. Can This Circular Battery Be Used in Extreme Temperatures?

Yes, the 503533 D-shaped LiPo battery is designed to function effectively in a wide range of temperatures. It has a discharge temperature range of -20°C to 60°C, making it suitable for use in outdoor devices, medical equipment, and wearable tech that may be exposed to harsh environmental conditions. The charge temperature range of 0°C to 45°C ensures safe and efficient charging in varying conditions.

Whether your device is used in cold climates, hot outdoor environments, or in extreme temperature conditions, the 503533 D-shaped battery will perform reliably without compromising the device’s functionality.

Part 7. Circular Battery Connector

When designing devices powered by circular batteries, the connector type is a crucial factor. Circular battery connectors come in various types, including pin, JST, and FPC connectors. These connectors ensure that the battery integrates smoothly into the device, allowing for secure and efficient power delivery.

At Ufine Battery, we understand the importance of a proper connection. We offer customizable connectors to suit your device’s needs, ensuring that the 503533 D-shaped battery integrates seamlessly with your product. Our expert team is ready to collaborate with you to provide the perfect connector solution for your application.

Part 8. Circular Battery Charger

The 503533 D-shaped LiPo battery requires a specific type of charger to ensure safe and efficient charging. For this battery, a LiPo battery charger with a charging voltage of 4.2V and the appropriate current rating (typically 0.5C to 1C) is necessary. Using the correct charger ensures that the battery is charged properly, preventing overcharging and maximizing its lifespan.

At Ufine Battery, we can also assist with providing custom charging solutions, including recommendations on chargers that are compatible with your D-shaped battery.
