Top 10440 Cylindrical LFP Battery Cell Manufacturers in China
The 10440 LiFePO4 battery is a high-performance cylindrical lithium iron phosphate cell, measuring approximately 10mm in diameter and 44mm in height (Ø10mm × 44mm). Designed for versatility and longevity, it serves as a compact and reliable energy solution for small electronic devices and customized battery pack assemblies. Multiple cells can be configured in series and parallel to meet specific voltage and capacity requirements, including 12V, 24V, and 48V battery systems.
Rated at a nominal voltage of 3.2V and a nominal capacity of 200mAh (optional 220mAh versions), this cell features a discharge cut-off voltage of approximately 2.0V and a maximum charge voltage of 3.65V. Engineered with a stable LiFePO4 chemical structure, the 10440 cell offers superior thermal stability, high discharge efficiency, and an extended cycle life—typically exceeding 2,000 cycles at 80% Depth of Discharge (DOD).
10440 Cell LiFePO4 Battery Cycle Life and Capacity Stability Curve
This chart illustrates the performance of the battery over 500 charge-discharge cycles. The red curve represents battery efficiency, remaining nearly at 100%, indicating a highly stable charging and discharging process with minimal energy loss. The blue curve shows battery capacity, starting at approximately 250 mAh and only slightly decreasing over long-term cycling, demonstrating excellent cycle life and capacity retention. Overall, the curve highlights the reliability and high-efficiency output of this LiFePO4 battery during extended use, making it ideal for applications requiring high stability and durability.
Unyielding Endurance: The VTCBATT IFR10440 400-Hour Torture Test
This isn’t just a cycle test chart; it’s a 400-hour wall of undeniable endurance. Spanning over half a month of relentless, continuous charge and discharge cycles, this data for the VTCBATT IFR10440 (220mAh) Lithium Iron Phosphate cell leaves zero room for doubt. Look at the dense crimson voltage band (2.0V – 3.6V). Through hundreds of hours of aggressive cycling, it remains rock-solid, showing absolutely no signs of fatigue, sudden voltage drops, or chemical degradation. Every single cycle mirrors the last with clockwork precision. Below it, the unbroken blue block of current data represents uncompromising power delivery. For a compact 10440 (AAA-size) cell to maintain this level of uniform consistency under such high-stress, prolonged conditions is the ultimate testament to superior LFP engineering. No fluff, just raw data. It’s rugged, enduring, and brutally reliable.
Unfiltered Performance: The VTCBATT IFR10440 Capacity Profile
This isn’t a sanitized marketing graphic; it’s the raw, unfiltered truth of the VTCBATT IFR10440 (220mAh) LFP cell in action. This dense web of overlapping charge and discharge curves maps voltage directly against capacity, revealing the battery’s true chemical heartbeat over countless cycles.
Notice the heavy, unyielding concentration of red lines forming the classic Lithium Iron Phosphate discharge plateau around 3.2V. Even amidst the rigorous demands of multi-cycle testing, the cell’s core performance remains firmly anchored. It consistently pushes to its full ~220mAh rated capacity before hitting the 2.0V cutoff, resisting premature voltage sag. The tight clustering at both the charging peak and the discharge floor proves that this compact 10440 cell doesn’t just promise capacity—it aggressively delivers it, cycle after cycle. It is a visual testament to resilient internal chemistry built to thrive under pressure.
