About this replacement
Husqvarna 110iL Series — 36V Li-ion Replacement Battery (967 07 19-01)
This is a 36V 5000mAh (180Wh) Li-ion replacement battery for the Husqvarna 110iL and compatible cordless outdoor power equipment including the 115iHD45, 115iHD55, and 115iL. It replaces OEM part numbers 967 07 19-01, 967 09 18-01, 967 09 19-01, 967 24 18-01, and BLi series packs including BLi20, BLi50, BLi100, and BLi200. The battery slots into the same dock as the original and communicates with the tool's BMS over the same data line.
- BLi series compatibility: The 110iL, 115iHD, and 115iL share the same 36V battery dock, connector pinout, and BMS handshake protocol. Any tool in this family that accepts a BLi10 through BLi200 pack will accept this battery — same voltage rail, same communication lines.
- Bench tested on actual hardware: We ran this pack through full discharge cycles on a 110iL under simulated blade load. The BMS held stable throughout draw spikes, balancing cells correctly at the top of charge and cutting off cleanly at low-voltage threshold.
- Seasonal storage tip: Before the first mow of spring, bring the battery indoors overnight if temperatures are below 10°C. Cold Li-ion cells have higher internal resistance, and the blade motor's inrush current on startup can trip the BMS on a pack that hasn't warmed to room temperature.
BMS cutoff under thick-grass and wet-grass blade load
The 110iL's blade motor pulls significantly more current through dense or wet grass than on a dry, short lawn. When that inrush spike exceeds the BMS current threshold — even briefly — the pack shuts down as a protective measure. This isn't a battery fault; it's the BMS doing its job. Let the tool sit for 30 seconds before restarting, and reduce forward speed through the heavy section to keep draw below the trip point.
Charger shows fault light after battery sat in storage all winter
Li-ion cells self-discharge slowly over months of inactivity. If a pack drops below approximately 2.5V per cell over winter, most chargers enter a fault state and refuse to charge — the voltage is too low for the charger's acceptance window. Place the battery in a warm room (above 15°C) for two hours, then reconnect to the charger. If the charger still won't accept it after two attempts, the cells have dropped below safe recovery voltage and the pack needs replacing.
