39.98 2025-08-11The BI20-4 is a 4Ah lithium-ion spare/replacement battery for Hyundai’s 20V Second Generation range of garden machinery and power tools.
It fully charges in just 120 minutes and delivers long runtimes, depending on the tool and task at hand. The integrated LED charge-level indicator keeps you informed of charging progress, while intelligent control that communicates with your tool provides real-time battery status updates.
Featuring innovative TES energy storage material, the battery absorbs heat and balances discharge temperature. Combined with advanced air channel technology, it offers optimised cooling and prevents overheating.
The robust shell structure protects internal battery cells from external impacts. Its leak- and shock-proof sealed electronics ensure reliable operation even in extreme conditions, providing enhanced safety and extended battery life.
The BI20-4 battery is free from the memory effect, so it can be recharged at any time without losing capacity. This ensures maximum flexibility and a longer service life—keeping your tools powered when you need them.
By purchasing additional 20V 4Ah batteries, you can keep multiple units charged and ready, reducing downtime between uses.
This 4Ah battery is suitable for use for the Hyundai 20V 2nd Generation Garden machinery and Power Tool range, including:
Drill Driver, Impact Driver, Impact Wrench, Angle Grinder, Sander, Reciprocating Saw, Jigsaw, Circular Saw, Grass Trimmer, Hedge Trimmer, Leaf Blower, Chainsaw, Pole Trimmer, and Pole Saw.
