HPC vs EDLC, Ultracapacitor and LIC: Compare the Design Fit
EDLC, ultracapacitor and supercapacitor commonly describe electric double-layer devices designed for rapid charge and discharge. A lithium-ion capacitor, or LIC, combines capacitor-type power characteristics with a lithium-intercalation electrode to provide a different balance of voltage, energy and power.
Long Sing Hybrid Pulse Capacitors(HPC) are battery-style rechargeable pulse-support cells intended for applications that remain at low background current for long periods, but periodically require short, demanding current bursts.
Unlike conventional same-end radial capacitors, the Long Sing HPC uses a cylindrical battery-style construction with positive and negative terminals positioned at opposite ends. This form factor supports compact integration alongside primary lithium cells, control electronics and industrial wiring assemblies.

Senior Hardware Engineer, Canada
We benchmarked HPC cells from five global suppliers. Long Sing showed 12% better pulse performance, lower ESR, and superior thermal stability. They are now our sole HPC partner.
HW
Hans W.
Engineering Director, Germany
The energy density of (Long Sing's) HPC1550 allowed us to shrink our LTE-M asset tracker enclosure by 35%. Their technical team assisted us with power budget simulations and delivered customized samples in under 5 days.
DR
David R.
VP of IoT Engineering, United States
We replaced a 2.7 V EDLC with the HPC1550 on the same PCB. One cell instead of two, 30 % more backup time, and the lot-to-lot ESR spread was the tightest we have measured.

Frequently Asked Questions
Everything you need to know about custom HPC development, production lead times, and quality assurance.
How does HPC prevent passivation in LiSOCl2 batteries?
The HPC operates in parallel with the ER battery. It supplies instantaneous high pulse currents while keeping the ER battery discharge current below its passivation threshold, thereby preventing voltage drops.
What is the minimum order quantity (MOQ)?
For standard single cells (HPC1520, 1530, 1550), MOQ starts at 100 units. For custom hybrid packs or wire harnesses, standard MOQ is 500 units. Free engineering sample packs are available for qualified OEM projects.
What is your standard production lead time?
Prototypes and engineering samples are shipped within 3–5 working days. Mass production orders are fulfilled within 2–3 weeks depending on volume and testing requirements.
Are Long Sing HPC products UN38.3 & UL certified?
Yes. All HPC models and composite battery packs pass UN38.3, UL1642, CE, and RoHS certifications for worldwide air and sea freight transportation.
Can you customize dimensions and connector types?
Yes. We offer turnkey mechanical customization including JST, Molex, Hirose connectors, specialized shrink tubing, and custom PCB pin soldering.
What warranty and after-sales support do you provide?
All industrial HPC cells come with a standard 10-year factory warranty and direct 24/7 Field Application Engineer (FAE) technical support for power management debugging.
