Tuflong HG-IS PLUS
Optimized for Delivery Vehicles and Commercial Start-stop Vehicles

High-charge-acceptance, high-durability battery specially designed for delivery vehicles and commercial start-stop vehicles
In addition to adopting the HPL structure with a proven track record as an industry pioneer and high-density active material, the adoption of super quick charging¹ achieves the high charge acceptance² and high durability³ required for delivery vehicles and commercial start-stop vehicles.
- Improved durability through the use of high-density active material
- Adoption of *super quick charging¹
- Adoption of high-performance electrode plates
- Adoption of heavy-duty grid structure (D size / E size)
- Adoption of low-resistance separator*4
- Adoption of HPL structure
*¹ Super quick charging: Proprietary technology that increases the surface area by finely dispersing discharge particles (PbSO₄) of the negative active material, enabling efficient electrical conduction to the active material.
(Adopted only for D26, D31, and E41 sizes.)
*² Based on in-house test results for D26 size.
*³ Comparison of durability of active materials used in HG and HG-IS for E41 size (based on in-house test results).
*4 Adopted for D size and H size.
Super Quick Charging That Maximizes Limited Charging Opportunities
Charge Acceptance Performance Improved Compared with the HG Series
*Super quick charging¹, which has a proven track record even in passenger car batteries, has been adopted to the HG series.
In addition, low-resistance separators that suppress resistance during charge acceptance are also used (D size, G size, H size).
As a result, a large amount of charge can be accepted in a short period of time, achieving a significant improvement in charge acceptance performance compared with the HG series.
The Secret to Durability
Dedicated Design Optimized for Delivery Vehicles and Commercial Sart-stop Vehicles
By adopting high-density active material and optimizing the overall design, further improvements in durability have been achieved. This product has been refined into a more suitable solution for delivery vehicles and commercial start-stop vehicles, where frequent engine stop–start cycles tend to accelerate active material degradation.
Features of High-Performance Electrode Plates
The Key Is the Combination of a Special Low-Antimony Alloy and High-Density Hard Paste
The negative plates use a calcium alloy, while the positive plates employ a low-antimony alloy and high-density hard paste. This combination achieves high strength, long service life, and excellent starting performance.
