SPR-003 Battery, 2025 New Upgraded 1900mAh Ultra High Capacity High Performance Lithium-ion Replacement Battery for Nintendo 3DS XL/New 3DS XL/ 3DS LL/New 3DS LL Game Console (Black, SPR-003, A)

Upgraded 1900mAh Super High Real-Capacity

Our SPR-003 battery is made of high-quality high-nickel ternary lithium cell (NMC 811) and nano-silicon carbon anode technology, which has the ability to increase energy density by 15% compared with the old version of the original battery and realize 1900mAh-2100mAh real capacity in the same volume (measured data value ≥ 1900mAh), beyond this capacity range of value are false labels, because the battery's volume has been The volume of the battery has already determined its maximum capacity value. And enhance lithium-ion embedding efficiency and reducing charge/discharge loss through the micrometer-level pore structure loss (energy utilization rate up to 90%).

Ultra-Long Battery Life

1900 mAh SPR-003 battery of Ultra-large real-capacity adopts directional growth of single crystal particles (particle size 5μm), eliminating the grain boundary cracks of traditional polycrystalline materials, with a cyclic expansion rate of ≤3% (conventional ≥12%), which fundamentally slows down the loss of active lithium. And the nano-silicon particles embedded in the elastic carbon matrix, with pre-lithiation process, compensates for the first-time efficiency to 94% (industry average 88%), and the anode structural integrity is up to 98.5% after 1000 cycles (SEM electron microscope measurement). This means you can get more power out of your 3DS XL/ New 3DS XL/ 3DS LL/ New 3DS LL game console, thus reducing the waste of frequent battery replacements and making your gaming life more save.

High Quality Smart IC Chip

Build-in high quality smart IC chip to prevent over-charging, over-discharging, short-circuit and over-heating, Intelligent regulation of charging and discharging power through chip, so that the working temperature of the battery cell is always locked in the golden zone of 25℃±3℃, Charging efficiency up to 96% (common chip ≤ 88%), full charge time shortened by 25%. Every battery is manufactured and tested under strict quality control standards. Multiple-protection for safer use for both user and devices.
