Tuflong ECO
Optimized for charging-controlled vehicles. A high-capacity, high-durability model.

Tuflong ECO adopts our proprietary Super quick charging technology, which delivers excellent charging acceptance performance. With rapid charging capability, this series is ideal for charging-controlled vehicles as well as short-distance, frequent-stop driving users.
- Built-in Charge Indicator installed
- Carrying handle attached
Super quick charging that makes the most of limited charging opportunities
Charging Acceptance Performance Up to 1.5 Times Higher Than Non–Super Quick Charging Models
In the ECO series, the use of a proprietary additive formulation finely disperses the negative active material, significantly increasing the amount of charge that can be accepted within a limited time.
By making the most of limited charging opportunities and enabling rapid charging, the operating time of the alternator is reduced, which also contributes to improved fuel efficiency.

Super quick charging extends battery Life
Super quick charging also suppresses sulfation
By significantly increasing the amount of charge that can be accepted within a given time, the state of charge recovers quickly even in charging-controlled vehicles. As a result, sulfation is less likely to progress.
