How do we compare to typical aftermarket batteries?

Battery Component	Our Standards	Common Aftermarket Manufacturer Standards
Plastic Case	Poly Carbonate (PC): Acrylonitrile butadiene styrene (ABS) = 7:3 Strict modling control processes to prevent cracks and defects Case withstands drops of 120cm	Low-grade regrind material often resulting in brittle quality and poor aesthetics
Li-ion Cell	100% Grade "A" cells (Sanyo, Samsung, Moli, Panasonic) for premium capacity and reliability.	80% of aftermarket factories use low grade or recycled cells.
Protection IC	Seiko S2854 for 3 or 4 series Li-ion cells. Mitsumi MM1414 for 3 or 4 series Li-Ion cells.	IC's from recycled battery packs are commonly used.
MOS-FET	Vishay SI4435, SI4407	IC's from recycled battery packs are commonly used.
Power Management IC	TI BQ Series: BQ2040, BQ2050, BQ2060, BQ2083, BQ2084, BQ2085, BQ20Z90 PowerSmart: PS501	IC's from recycled battery packs are commonly used.
EEPROM	Microchip 24LC02	Various Standards
Thermal Fuse	139oC Thermal Fuse	Standard or no Thermal Fuse is common
PCM	Each PCM is specifically designed in house by our senior engineers.	Outsourced with minimal input on quality control.
Isolation Materials	Strong, durable, 100% insulated Mylar tape to secure batteries and wires. Heat-resistant to avoid potential short circuits caused by high temperatures during welding & assembly. Hard to puncture insulation tape used on metal surfaces, nickel plates and PCM.	Non-electrical, household-type tape to secure cells and wires; offering poor insulation characteristics and low adhesiveness. Cost reducing methods result in a greater chance for short-circuits, overheating, and leakage.
