LIR1040 Button Cell Battery
October 24 2025 Editor Becky W
In today’s era of smaller and smaller smart wearable devices, are you still frustrated by the lack of energy that can provide continuous current?
Today, we solemnly introduce to you a tried and tested “all-rounder” in the field of miniature power supply – LIR1040 rechargeable button cell. It is not only a carrier of energy, but also a reliable partner for you to realise innovative product design.
LIR1040 is a type of rechargeable button cell battery.
LIR stands for the essence of its technology – Li-ion (Li-ion) rechargeable (Rechargeable), to ensure that its energy source is advanced and economical.
The 1040 represents the size of the battery, which is 10mm in diameter and 4.0mm in length; similarly, the LIR1054 is a button cell with a diameter of 10mm and a length of 5.4mm, and so on.
Before we dive into the details, we can quickly summarise the benefits of the LIR1040 in four keywords:
Compact size: the classic 1040 size provides the energy cornerstone for the ultimate compact device design.
Recyclable Charging: Say goodbye to disposable waste once and for all, and realise energy recycling to significantly reduce full life cycle costs.
Stable Voltage Platform: Provides smooth energy output throughout the discharging process, protecting precision circuits and chips.
Long service life: After hundreds of charging and discharging cycles, it still maintains excellent capacity, guaranteeing the long-term reliability of the product.
LIR1040 battery has four major advantages, let me explain in detail next.
Advantage 1: The classic round button shape can perfectly fit the design layout of the PCB board, easily embedded in a variety of compact housing, freeing up valuable equipment space for you, is the key to achieve product miniaturisation, thin and light to help.
Advantage 2: Unlike disposable batteries whose voltage drops continuously, the LIR1040 provides an extremely stable operating voltage throughout the discharge process. This means that your devices – especially voltage-sensitive RF modules and audio components – will perform consistently from full charge until they need to be recharged, eliminating performance degradation or abnormal functionality caused by voltage fluctuations.
Advantage3: One LIR1040 can be recharged hundreds of times. For end-users, this means solving once and for all the hassle of frequent battery replacements and the cost of ongoing purchases. For our B-side customers, this translates directly into higher added value and more attractive selling points.
Advantage 4: Adopting a sturdy steel shell structure, the LIR1040 is equipped with excellent physical protection. It can effectively withstand the crush and impact in daily use, and fundamentally eliminates the risk of liquid leakage that may exist in soft pack batteries, adding a solid line of defence for the safety of your products.
By choosing our LIR1040, you get not only a battery, but also a reliable guarantee and in-depth cooperation.
preliminary negotiation
Communicate your specific application scenarios, performance requirements and space constraints. Our technical team will confirm the product model, specifications and customisation requirements accordingly to ensure that the solution is accurately matched.
Programming and quotations
Based on technical confirmation, we provide a detailed proposal with product specifications, price, delivery time and terms of service to ensure transparency and provide a clear basis for your decision.
Sample testing and validation
We prioritise the sending of samples for you to carry out comprehensive performance and compatibility testing. This phase is designed to ensure that the product fully meets your design requirements through practical verification.
Contract signing and first order placement
After sample confirmation, both parties formally sign the supply contract and quality agreement. Upon receipt of your first formal order, we will start the production scheduling process to ensure on-time delivery.
Volume Delivery and Continuous Service
Entering the stage of stable cooperation, we guarantee the reliable supply and consistency of bulk products. At the same time, account managers provide exclusive services and make regular return visits to ensure smooth and worry-free long-term co-operation.
