About this replacement
Worx Landroid L1500 / L2000 Series — 28V Li-ion Replacement Battery (WA3225)
This 28V 2500mAh (70Wh) Li-ion battery replaces the Worx WA3225, WA3226, and WA3565 packs. It fits the Landroid L1500, L2000, L2000 Wi, WG794, and over 30 additional Worx robotic mower models. Same voltage rail and connector as the original — the mower's dock and onboard BMS treat it as a native pack.
- Landroid L1500 and L2000 compatibility: These models share the same 28V battery architecture, dock charging circuit, and BMS handshake protocol. One battery format serves the whole platform. Swapping between units in this family requires no adapters or setting changes.
- Bench tested on actual hardware: We ran this pack through the full dock charge cycle and triggered the blade motor under simulated load. The BMS held voltage within spec at both low-state-of-charge and full-load draw. No false cutoffs on initial cycles.
- Seasonal storage before first spring mow: If the mower sat through winter in an unheated garage, bring the battery indoors overnight before use. Below 10°C, Li-ion cells carry higher internal resistance — the blade motor's inrush current on a cold pack can trip the BMS before the mower completes its first row.
BMS cutoff under thick grass and wet-lawn blade load
The Landroid's blade motor pulls significantly more current through dense or wet grass than on a dry, short lawn. If the pack's BMS detects a current spike beyond its protection threshold — common in heavy-growth conditions — it will cut power to the motor. This is a protection event, not a battery fault. After the cutoff, the mower typically returns to dock and resumes once the pack stabilises above its recovery voltage of around 24V.

Li-ion cells self-discharge over months of storage. If the pack drops below approximately 20V, many charger circuits classify it as a failed cell and refuse to begin a charge cycle. Remove the battery from the dock, let it sit at room temperature for 30 minutes, then re-seat it firmly and retry. If the dock still shows a fault, the original pack has likely discharged past the charger's acceptance threshold — this replacement battery arrives at a safe storage charge and will begin charging immediately on the first dock connection.
