Zucchetti 25.2V Cordless Lawn Mower Replacement Battery 075Z01300A

Zucchetti 075Z01300A / 075Z61700A — 25.2V Li-ion Replacement Battery

This 25.2V 2300mAh (57.96Wh) Li-ion battery pack replaces OEM parts 075Z01300A and 075Z61700A in Zucchetti cordless lawn mowers. It matches the original voltage rail and connector format so the charger and BMS handshake operate as they would with the factory pack. Capacity figure is taken from the product specification — not extrapolated from cell count.

• Zucchetti mower platform fit: Both OEM part numbers share the same 25.2V six-cell configuration, connector pinout, and BMS communication protocol. That is why a single replacement pack covers both references without modification.
• Bench tested on actual hardware: We ran this pack through a simulated blade-start inrush draw and monitored BMS response across five consecutive discharge cycles. The protection circuit held within spec on motor-start surge without nuisance tripping under normal grass load conditions.
• Seasonal storage tip — before first spring cut: If the mower sat through winter, bring the battery indoors overnight before the first use if temperatures are below 10°C. Cold Li-ion cells carry higher internal resistance, and the blade motor's inrush current on a cold pack can trip the BMS before the mower takes a single pass.

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

The blade motor on a cordless mower draws its highest current at startup and again when it bites into dense or wet grass. If that draw exceeds the BMS overcurrent threshold — even briefly — the pack shuts down as a protection measure, not a fault. This is not a defective battery. Allow a 10–15 second pause, then restart. If cutouts repeat consistently, reduce the cutting width or raise the blade height to lower the per-pass motor load.

Charger refuses to accept the pack after winter storage

Li-ion cells left in a partially discharged state over several months of garage storage can drop below the minimum acceptance voltage the charger checks before it begins a charge cycle. The charger is not broken — it is rejecting a pack it reads as over-discharged. Place the battery in a warm indoor space (18–22°C) for two hours, then retry the charger. If the charger still shows a fault, the cell voltage has likely fallen below 2.5V per cell and recovery requires a bench charger capable of a trickle pre-charge at around 0.1C.
