Technical Support & FAQ

We specialize in two distinct inventory categories to meet different budget requirements:

• New Old Stock (NOS): 100% Authentic, unused branded components from surplus industrial inventory.
• Original Pulls: High-quality components carefully dismantled from professional equipment. Each unit undergoes rigorous re-certification.

We strictly source from reputable industrial partners and verify laser-etched serial numbers and manufacturing codes directly from brands like Maxwell and SAMWHA. No generic or counterfeit imitations are sold.

Every single unit undergoes our local facility's 4-step QC protocol:

1. Visual Inspection for physical integrity.
2. Capacitance Measurement (verified to meet 90%+ original rating).
3. ESR efficiency testing.
4. Leakage current stability check.

Rated for 1M+ cycles. Since our pulls are typically sourced from lightly-used backup systems, they generally retain over 80-90% of their theoretical service life.
