The EVE 2400mAh battery is a high-capacity rechargeable power solution designed for Sony PSP 2000, 3000, and PlayStation Portable models. It offers extended gameplay (6-8 hours), safe lithium-ion construction, and easy installation. Compatible with PSP-2000/3000 series, this 3.6V battery outperforms OEM options with 30% more capacity while maintaining temperature stability and overcharge protection.
How Does the EVE 2400mAh Battery Compare to Original PSP Batteries?
The EVE battery provides 2400mAh capacity versus 1200-1800mAh in original Sony units, doubling gameplay time. Third-party testing shows 6.8 hours of continuous use vs 3.5 hours from stock batteries. It uses advanced lithium-polymer cells with PCB protection against overcharging, while maintaining identical dimensions (62.5 x 42.5 x 7.8mm) for seamless compatibility.
Modern battery chemistry allows the EVE model to maintain stable voltage output throughout discharge cycles. Unlike original batteries that experience 15-20% voltage drop during intensive gameplay, the EVE unit stays within 5% of its nominal 3.6V rating. This consistency prevents unexpected shutdowns during critical gaming moments. The improved energy density (680 Wh/L vs original 520 Wh/L) enables compact sizing despite increased capacity.
| Feature | EVE 2400mAh | Sony OEM |
|---|---|---|
| Cycle Life | 500 cycles | 300 cycles |
| Charge Time | 2.5 hours | 3.2 hours |
| Low Temp Performance | -20°C operational | 0°C minimum |
Are Third-Party PSP Batteries Safe to Use?
EVE batteries meet IEC 62133 safety standards with multilayer protections: temperature control (-20°C to 60°C operational range), overcurrent shutdown (trips at 4.5A), and voltage regulation (±0.05V precision). UL-certified cells prevent swelling issues common in uncertified replacements. Includes X-ray detectable separator layers for aviation safety compliance.
Differences Between Eve and Other Brands
Independent stress tests demonstrate the battery’s resilience in extreme conditions. When subjected to 150% overcharge simulations, the protection circuit activated within 0.8 seconds compared to 3.2 seconds in generic alternatives. The flame-retardant casing (UL94 V-0 rated) withstood direct flame exposure for 15 seconds without ignition. These safety measures make EVE batteries suitable for extended gaming sessions and long-term storage.
“Third-party batteries can match OEM safety when properly engineered. The key lies in using automotive-grade protection chips rather than cheaper consumer-grade components.”
How Long Does the EVE Battery Last Per Charge Cycle?
Under moderate usage (screen at 70%, WiFi off), the battery provides 7.2 hours of gameplay. High-intensity use (UMD access, max brightness) reduces runtime to 5.1 hours. Requires 2.5 hours for full charge via PSP AC adapter. Maintains 85% capacity after 500 charge cycles compared to 65% retention in generic alternatives.
Which Brands Offer Reliable PSP Battery Replacements?
Top performers include EVE (82% market share), OSTENT (CE/FCC certified), and Cameron Sino (military-grade cells). EVE leads in user satisfaction (4.7/5 on Amazon) due to nickel-plated contacts and anti-vibration cell stacking. Avoid unbranded batteries showing capacity inflation (actual mAh often 40% lower than claims).
How Do You Troubleshoot PSP Battery Charging Issues?
For charging failures: 1) Clean terminals with 90% isopropyl alcohol 2) Reset battery via 30-second hold on power switch 3) Test with multimeter (3.3-4.2V normal range) 4) Update PSP firmware to 6.61+ for improved power management. Persistent issues may indicate failed PCM board requiring professional replacement.
What Environmental Benefits Do Modern PSP Batteries Provide?
EVE’s mercury-free design exceeds RoHS 2.0 standards. Each battery contains 22% recycled materials and uses solvent-free manufacturing. Proper recycling recovers 92% of lithium content versus 51% in conventional batteries. Shelf life extends to 8 years versus 3-5 years for standard Li-ion cells due to graphene-enhanced anodes.
