ML2430 3V 100mAh Rechargeable Lithium Aluminum Alloy Button Cell Battery

Heavy-Duty Micro Power. 1000-Cycle Endurance. The High-Capacity Sentinel for Enterprise Hardware.
When system down-time translates directly to lost revenue, data corruption, or compromised security, hardware architects look beyond standard micro-cells. The ML2430 3V 100mAh Rechargeable Lithium Aluminum Alloy Battery is engineered for high-drain, long-duration backup applications where typical 15mAh to 30mAh coin cells fail to provide an adequate safety margin.
By leveraging a wider φ24.5 × 3.0mm form factor and weighing 4.2g, this secondary cell packs a massive 100mAh energy reservoir. It provides your critical circuits with an unprecedented operational runway, eliminating the maintenance overhead and environmental waste of disposable primary batteries.

Core Engineering Advantages & B2B Value
1. The 100mAh Capacity Benchmark
The standout feature of the ML2430 is its heavy-duty 100mAh capacity. For hardware running multi-chip arrays, complex real-time clocks (RTC), or devices requiring frequent background data logging during main power outages, this cell provides up to 5 times the standby life of standard 20mm coin cells.
2. Premium 1000/500 Cycle Lifetime
Built with a highly stable lithium aluminum alloy crystal lattice, the ML2430 withstands 1,000 standard charge/discharge cycles (and up to 500 cycles under deep discharge test protocols). Because real-world backup environments typically utilize shallow micro-cycling, this cell easily matches or outlasts the 10-to-15-year service life of industrial computing infrastructure.
3. Industrial Thermal Tolerance (-20°C to +70°C)
The battery’s internal chemistry is formulated to resist passivation in freezing outdoor field equipment (-20°C) while remaining completely stable against internal pressure increases or rapid self-discharge in high-temperature operating environments (+70°C).
4. Precision Voltage Regulation
Delivers a sustained, flat 3.0V discharge curve. This consistent voltage keeps sensitive CMOS registers, cryptographic modules, and system clocks completely stable, preventing voltage drops that trigger accidental firmware wipes.

Frequently Asked Questions
Q1: Why should I choose an ML2430 over an ML2032 battery?
A: The ML2430 features a larger diameter (φ24.5mm vs φ20.0mm), which allows it to deliver a 100mAh capacity—nearly double the 65mAh capacity of the ML2032. If your device requires extended backup runtimes, operates in areas with long power-outage windows, or drives a slightly higher standby current, the ML2430 is the superior engineering choice.
Q2: Can the ML2430 be used as a direct replacement for a disposable CR2430?
A: No, not without verifying your circuit design. While both cells share identical physical dimensions, the ML2430 is a rechargeable (secondary) cell, while the CR2430 is a disposable (primary) lithium battery. The host board must be equipped with a managed charging circuit to safely replenish the ML2430 over time.
Q3: How does the 1,000-cycle rating translate to real-world deployment?
A: In typical RTC and CMOS backup circuits, the battery remains fully charged by the main power line and only experiences shallow discharges during temporary outages. Under these micro-cycling conditions, the ML2430 easily achieves its maximum lifespan, running maintenance-free for over a decade without needing replacement.
