What is the LP402025 Battery?

The LP402025 is a lithium polymer (LiPo) rechargeable battery. The model number itself reflects its physical dimensions: 4.0 mm thickness, 20 mm width, and 25 mm length. Despite its small footprint, it delivers stable voltage output and long-lasting performance, making it a go-to choice for OEMs and engineers developing next-generation IoT and wearable devices.

At its core, the LP402025 is a 3.7V LiPo battery with a typical capacity of 150mAh. It’s engineered for consistent discharge, low internal resistance, and safe operation under strict international standards. Manufacturers and procurement managers often choose this model not for consumer replacement, but as a standardized power source integrated into production runs of thousands of devices.

LP402025 Battery Features

The LP402025 lithium polymer battery combines compact dimensions with dependable performance, making it well-suited for modern portable and IoT devices. Below are the key features that matter most to engineers, procurement officers, and manufacturers:

1. Compact and Lightweight Design

With dimensions of just 4.0mm (thickness) × 20mm (width) × 25mm (length), the LP402025 provides a slim profile that fits seamlessly into wearables, medical patches, and small IoT devices. Its weight of around 3–4 grams helps reduce the overall device mass without sacrificing energy output.

2. Reliable Voltage and Stable Output

The battery delivers a nominal voltage of 3.7V, ensuring compatibility with most low-power electronic circuits. It maintains a stable discharge curve, which is critical for devices requiring consistent performance over time, such as wireless sensors or health monitors.

3. Long Cycle Life

Engineered with high-quality lithium polymer chemistry, the LP402025 supports 300–500 charge cycles under standard usage conditions. This durability makes it a cost-effective option for manufacturers targeting products with a multi-year lifespan.

LP402025 Used in Compact Electronics

The LP402025 is not a consumer-grade “off-the-shelf” battery; it is a purpose-driven component integrated into products that demand both small form factor and reliability.

IoT Devices and Smart Sensors

IoT products are one of the fastest-growing categories for LP402025 adoption. Smart sensors deployed in logistics, healthcare, or environmental monitoring rely on lightweight batteries that fit into small enclosures yet still power wireless communication modules. With its compact design and stable voltage, the LP402025 enables extended uptime without increasing device size.

Wearable Devices and Medical Instruments

From health trackers to medical patches, wearables require thin, lightweight, and safe power solutions. The LP402025 meets these requirements, providing consistent energy delivery without adding bulk. In the medical field, reliability and safety certifications make it an ideal candidate for use in FDA- or CE-approved devices.

Portable Consumer Electronics

Although primarily targeted at B2B applications, the LP402025 is also found in certain niche consumer electronics like MP3 players, Bluetooth devices, and handheld gadgets. These products often need batteries that can be customized with connectors or protection circuits.

LP402025 vs Similar LiPo Models

The LP402025 is part of a broader family of lithium polymer batteries, where slight changes in dimensions can determine fit and capacity.

LP402025 vs LP302025 – Size and Capacity Differences

The LP302025, while similar in length and width, is thinner at 3.0 mm. This makes it lighter, but it also comes with reduced capacity, typically around 120mAh. Engineers weighing these two models often need to balance capacity vs. device thickness, with the LP402025 being chosen when a slightly thicker profile is acceptable in exchange for longer run-time.

When to Choose a Custom LiPo Solution

Some devices require unique shapes or higher capacity without compromising weight. In these cases, OEMs work directly with suppliers to design custom LiPo packs with PCM, connectors, or even combined cells for increased energy density. The LP402025 serves as a strong baseline for such modifications, often being the starting point for custom builds.

Sourcing LP402025 for OEM and Industrial Use

For businesses, sourcing the right battery is as important as the device itself. Delays or inconsistent quality can jeopardize production schedules and product launches.

Bulk Procurement Considerations

OEMs and utilities often purchase the LP402025 in bulk for continuous assembly line integration. Reliable suppliers provide not only the cells but also ensure consistent batch quality, proper testing, and packaging for safe global transport.

Customization Options – Connectors, PCM, Wire Length

Depending on the end application, the LP402025 can be configured with safety circuits (PCM), temperature sensors (NTC), or pre-assembled connectors such as JST or Molex. These modifications reduce assembly time for OEMs and improve compatibility with specific devices.

Certifications and Compliance (UN38.3, CE, RoHS)

Compliance is a non-negotiable factor for international shipment and integration into regulated industries. UN38.3 certification ensures the LP402025 passes stringent transport safety tests. CE and RoHS certifications demonstrate compliance with European directives on safety and environmental standards.
