Modern horology demands micro-power sources that are not only compact but capable of sustaining constant, reliable voltage over extended operational lifespans. As a leading OEM/ODM Watch Battery Manufacturer & Supplier, we recognize that watch movements, both classical quartz and modern multi-functional smartwatches, depend heavily on precision chemical engineering. The stability of the micro-battery dictates the accuracy, lifetime, and safety of the entire timekeeper mechanism.
For quartz movements, silver oxide (SR) cells remain the gold standard due to their flat discharge curves and high energy-to-volume ratio. Meanwhile, contemporary smart wearables rely on specialized lithium manganese dioxide (CR/CP) and custom rechargeable lithium-ion solutions to support high-drain RF communication, biological sensors, and dynamic displays. To ensure zero-defect integration, watch brands require batteries engineered with advanced anti-leakage seals, corrosion-resistant steel casings, and stabilized chemical compounds that mitigate self-discharge over decades.
Dongguan Ciso Tool Co., Ltd. was founded in 2006 and is a professional manufacturer specializing in the research, development, and production of mid-to-high-end precision watch components and complete watch solutions. Formerly operating under an earlier corporate structure, the company has grown into a modern manufacturing enterprise with strong integrated capabilities across design, engineering, and precision production.
Our commitment to horological excellence has driven our vertical integration strategy. In watchmaking, energy supply cannot be isolated from structural casing and movement engineering. By combining our micro-machining expertise with advanced chemical cell packaging, we provide comprehensive, reliable OEM/ODM solutions. We operate an independent industrial facility covering over 20,000 square meters and employ more than 500 skilled staff members, including a dedicated R&D team of over 60 professionals. With advanced production equipment, strict quality control systems, and experienced technical personnel, Ciso is committed to delivering high-precision, high-consistency products for global watch brands.
Choosing the correct electrochemical configuration is crucial to long-term component safety. Below is a comparative engineering reference for watch manufacturers sourcing power components.
| Cell Class | Voltage (Nominal) | Primary Application | Capacity Range | Leakage Risk Mitigation | Working Temp Range |
|---|---|---|---|---|---|
| Silver Oxide (SR) - Low Drain | 1.55 V | Analog quartz watch movements with minimal sensor loads | 8 mAh – 165 mAh | KOH electrolyte with double-layer barrier structure | -10°C to +60°C |
| Silver Oxide (SR) - High Drain | 1.55 V | Analog/digital watches with LED backlighting or alarms | 15 mAh – 200 mAh | NaOH electrolyte optimized for structural pressure | -10°C to +60°C |
| Lithium Coin (CR) | 3.0 V | Hybrid smartwatches, digital modules, radio-controlled units | 30 mAh – 1000 mAh | Organic non-aqueous electrolyte, high hermetic seal | -30°C to +85°C |
| Lithium-Ion (Rechargeable) | 3.7 V - 3.82 V | Advanced smart wearables, PPG heart-rate tracking sensors | 15 mAh – 450 mAh | Aluminium-laminated pack, PTC & CID safety valves | -20°C to +60°C |
Standard off-the-shelf cells frequently suffer from voltage drops under load. We work closely with brand engineers to customize the internal resistance (IR) and discharge rate profiles. This ensures that when a watch activates high-draw features such as Bluetooth synchronization or backlighting, the cell maintains its stability without triggering premature low-voltage warnings.
For space-constrained PCB installations, we provide customized nickel-plated termination tabs, pin geometry, and micro-wire assemblies. Whether you require surface-mount SMT compatibility or direct wave-soldering pins, our precision tooling department executes exact specifications to ensure effortless integration into automated lines.
Battery leakage can ruin an expensive luxury caliber. Our proprietary manufacturing utilizes double-injection molded polyphenylene sulfide (PPS) gaskets along with high-viscosity sealant coating. Each production lot undergoes vacuum thermal stress screening to assure 100% reliable containment of alkaline or lithium salt solutions.
Located in Dongguan, the heart of advanced hardware manufacturing, Ciso combines vertical integration, localized raw material sourcing, and automation to provide exceptional commercial and technical advantages.
We source high-purity silver chemicals and premium lithium metal directly from domestic industrial chemical suppliers. Our strategic volume agreements minimize price fluctuations, protecting our clients from volatility in silver and lithium markets.
By investing in fully automated assembly systems, we reduce variable human error during delicate cell stack placement and high-pressure crimping. This machinery guarantees consistent internal pressure, leading to stable discharge characteristics.
Our location in Dongguan enables direct routing to the Shenzhen and Hong Kong deepwater ports and international airports. This setup shortens standard transit times to North America and Western Europe to 15–20 days, and just 5–7 days for air freight.
Guided by the principle of “Quality First, Integrity Supreme,” Ciso emphasizes excellence in every production process. Below is an overview of our state-of-the-art facilities, handling complex metal stamping, high-tolerance machining, testing, and cleanroom assembly.
Regulatory requirements across global markets have accelerated the phase-out of mercuric oxide components. Modern silver-oxide cells rely on complex organic corrosion inhibitors and surface treatments to prevent hydrogen gas generation within the cell. This design maintains safety and shelf stability without resorting to heavy metals.
As smart wear applications demand more functionalities within compact 40mm form factors, maximizing volumetric energy density is essential. By utilizing sub-micron particle size distribution in the active cathode material, we achieve up to 15% more capacity than standard models. This increases the run time of connected wearables.
We are actively researching solid-state micro-cells, which replace liquid electrolytes with thin-film ceramic separators. This technology eliminates internal leakage paths, handles broad operational temperatures (-40°C to +120°C), and operates safely in proximity to high-value mechanical movements.
Shipping micro-batteries requires strict adherence to international safety standards. Working with a reliable manufacturer ensures your supply chain is compliant and avoids costly customs delays.
At Ciso, we carry out comprehensive safety assessments on every batch. Our packaging solutions use customized conductive trays and insulation spacers to eliminate short-circuit risks during transit. We provide full documentation support—including Material Safety Data Sheets (MSDS), UN38.3 test summaries, and declaration reports for dangerous goods—streamlining customs clearance for your logistics team.
