Worx WA3565 28V Lawn Mower Compatible Battery 2500mAh

Worx WG795E / Landroid WG795E — 28V Li-ion Replacement Battery (WA3565)

This 28V 2500mAh (70Wh) Li-ion battery replaces the original pack on the Worx WG795E and WG795E Type 2 cordless lawn mower. It fits the blade motor circuit on all listed WG795E variants and covers OEM references WA3565 TYPE 2, 50022580, 50022713, 50026980, and 50029621. Check your current pack for any of those part numbers before ordering.

• WG795E platform fit: All WG795E variants share the same 28V connector housing and BMS handshake protocol. The Type 2 revision carried a firmware update on the charger side but kept the same cell specification, so one battery covers both generations.
• Bench tested on actual hardware: We ran this pack through full charge and load cycles on a WG795E deck motor. The BMS held correct cutoff voltage under simulated high-draw blade starts and returned accurate state-of-charge to the charger without fault codes.
• Seasonal storage tip: Before first use of the season, bring the battery indoors overnight if temperatures are below 10°C. Cold Li-ion cells have higher internal resistance, and the blade motor inrush current on a cold pack can trip the BMS before the mower even takes a full cut.

BMS cutoff on thick-grass or wet-grass blade load

The WG795E blade motor draws significantly more current when cutting wet or overgrown grass. If the BMS detects current spikes beyond its threshold — typically caused by the motor stalling momentarily against dense material — it will cut power to protect the cells. This is not a battery fault; it is the protection circuit doing its job. Slow the mower's forward speed through dense patches to keep inrush current below the BMS trip point.

Charger shows fault light after mower sat unused all winter

Li-ion cells self-discharge slowly during storage. A pack left in the garage over winter can drop below the charger's acceptance voltage — typically around 18–20V on 28V packs — causing the charger to flag a fault rather than initiate a charge cycle. Place the battery in a warm room (above 15°C) for two hours and reinsert it into the charger. If the fault clears, the charger has re-accepted the pack; if not, check cell voltage with a multimeter at the pack terminals and confirm it reads above 20V before assuming a failed cell.
