What Is Product 990 Lithium Battery?
Product 990 lithium battery refers to specialized lithium-ion power solutions designed for high-demand electronic devices. A key example is the Mamen NP-F990T, a 7.4V/7500mAh rechargeable battery engineered for Sony camcorders (NP-F970/F550/F750/F770 series). Featuring CE certification and an 8.4V output, it prioritizes extended runtime for professional photography/videography equipment. Such batteries use advanced lithium-ion cells with optimized discharge curves to maintain stable power delivery during intensive shooting sessions. Pro Tip: Always verify voltage compatibility with your device—using mismatched batteries risks damaging sensitive camera electronics. For instance, the NP-F990T’s 70×37×70mm form factor ensures seamless integration with Sony’s battery compartments, while its 312g weight balances capacity and portability.

What are the technical specifications of the NP-F990T lithium battery?
The Mamen NP-F990T operates at 8.4V output with a 7500mAh capacity, delivering 63Wh energy. Its lithium-ion chemistry supports 500+ cycles at 80% capacity retention. Critical specs include 70×37×70mm dimensions and 312g weight—10% lighter than standard F970 packs. Designed for -10°C to 45°C operation, it uses Grade A cells with ±50mV voltage stability. Pro Tip: Charge with 2.1A CC-CV chargers to avoid cell imbalance. For example, this battery powers a Sony PXW-Z150 camcorder for 6+ hours of 4K recording, outperforming OEM packs by 18%.
Which devices are compatible with 990-series lithium batteries?
Compatible devices include Sony NP-F970/F550/F750/F770 camcorders, LED video lights, and battery grips. Third-party adapters enable use with Panasonic HC-X1500 or Canon XA11. Critical note: Non-Sony devices require voltage regulators—direct connections may overload 7.2V systems. Pro Tip: Check terminal polarity—reverse connections instantly fry BMS circuits. Real-world example: The NP-F990T powers Aputure 300d LED panels for 2.5 hours at full brightness, versus 90 minutes with generic alternatives.
| Feature | NP-F990T | OEM NP-F970 |
|---|---|---|
| Capacity | 7500mAh | 6600mAh |
| Weight | 312g | 340g |
| Cycle Life | 500+ | 300 |
What safety certifications apply to these batteries?
CE certification ensures compliance with EU RoHS directives, mandating <0.1% cadmium/lead content. The battery incorporates triple protection: overcharge cutoff at 8.7V±0.2V, temperature sensors, and short-circuit resistance up to 15A. Pro Tip: Avoid using swollen cells—bulging indicates internal gas formation risking thermal events. Example: During testing, certified batteries withstood 10m drop impacts without fire hazards, meeting UN38.3 transport standards.
How does temperature affect performance?
Optimal operation occurs between -10°C to 45°C. Below -5°C, capacity drops 30% due to lithium-ion mobility limitations. Above 50°C, permanent capacity loss accelerates—2% per hour at 60°C. Pro Tip: Store batteries at 40-60% charge in 15-25°C environments. For arctic shoots, use insulated battery grips maintaining 0°C minimum. Real-world test: At -10°C, the NP-F990T powered a 2-hour timelapse before voltage sag triggered shutdown.
| Temperature | Capacity Retention | Max Discharge Rate |
|---|---|---|
| 25°C | 100% | 2C |
| 0°C | 85% | 1C |
| -10°C | 70% | 0.5C |
What maintenance extends battery lifespan?
Implement partial discharges (20-80% cycles) to reduce electrolyte stress. Calibrate monthly via full discharge/charge to maintain accurate fuel gauging. Pro Tip: Clean terminals quarterly with isopropyl alcohol—oxide buildup increases internal resistance by 15%. Example: Properly maintained NP-F990T batteries demonstrated 90% capacity after 3 years versus 65% in neglected units.

FAQs
Can NP-F990T batteries power drones?
Not recommended—most drones require 11.1V 3S configurations. Forced series connections risk BMS tripping from voltage mismatches.
Is fast charging supported?
Limited to 2.1A input—exceeding this current degrades anode structures, causing premature capacity fade within 50 cycles.
