Why Choose HNF Battery?

High-Capacity 4.0Ah for Longer Runtime

At 4.0Ah and 160Wh, the RY40406 delivers significantly longer runtime than standard 2.0Ah packs — ideal for extended outdoor work sessions including lawn maintenance, trimming, and landscaping without frequent recharging.

Grade-A Cells for Consistent Performance

We use only Grade-A lithium-ion cells in every RYOBI RY40406 40V battery pack. Grade-A cells deliver stable voltage output, longer cycle life (500+ charge cycles), and lower self-discharge compared to generic replacements. Your tools run at full power longer and your battery lasts for years, not months.

Every battery includes a fully integrated Battery Management System (BMS) protecting against overcharge, over-discharge, short circuit, and overheating — safeguarding both your battery and your tools.
