20V Yard Force Easymow 260 Replacement Battery 2600mAh

Yard Force Easymow 260 — 20V Li-ion Replacement Battery (1920763001)

This is a 20V 2600mAh (52Wh) Li-ion battery that replaces OEM part 1920763001 in the Yard Force Easymow 260 cordless push mower. It also fits the MB 400, Mowbest, and Mowbest 805 Compact models that share the same 20V battery platform. If the original pack has lost charge capacity or stopped holding charge entirely, this is the direct replacement.

• Easymow 260 / MB 400 platform fit: These models share the same 20V battery rail, connector pinout, and BMS handshake protocol — the same pack works across all listed models without adapters or modifications.
• Bench tested on actual hardware: We ran this pack through full charge-discharge cycles on the Easymow 260 platform, confirming the BMS handshake initialised correctly, cell balancing activated on the first charge, and the pack delivered stable voltage under simulated blade-motor load.
• Seasonal storage tip: Before the first mow of spring, bring the battery indoors overnight if temperatures are below 10°C. Cold Li-ion cells carry higher internal resistance, and the blade motor's inrush current can trip the BMS on a pack that hasn't warmed up to room temperature.

BMS cutoff under thick-grass and wet-grass blade load

The Easymow 260 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, the pack shuts down as a protection measure — not a battery fault. A new pack may be more sensitive to this until the cells complete their first few conditioning cycles. If cutouts happen consistently in thick sections, slow your mowing pace to reduce sustained motor load and allow the current draw to stay within the BMS window.

Charger won't accept the pack after winter storage

Li-ion cells that self-discharge below approximately 2.5V per cell over a long storage period fall outside the voltage window most chargers will accept for a standard charge cycle. The charger reads the pack as faulty and refuses to initiate. To recover the pack, leave it on the charger for up to 30 minutes — many chargers include a trickle pre-charge mode that will bring cells back above the acceptance threshold before switching to full charge. If the fault light stays on past 30 minutes, check that the charger output voltage reads at least 21V with a multimeter.
