What It Is

This is an aftermarket lithium-ion battery replacement (5200mAh) designed for Husqvarna robotic mowers. It powers the mower’s cutting and navigation systems, intended for use when the original battery wears out.

Fitment & Compatibility

• Compatible models: Husqvarna AM430X, AM440, AM550, Automower 450X (2018), Automower 520 (2018/2019), Automower 550.
• OEM part cross-reference: Replaces Husqvarna battery part number 579 88 18-02.
• Physical check required: Measure your original battery compartment dimensions (approx. 150 x 65 x 38 mm / 5.9 x 2.6 x 1.5 in). This battery must fit snugly without modification.
• Connector type: Verify your mower uses a 2-pin JST connector (common on these models). If your mower has a different plug, you’ll need an adapter or a different battery.
• Voltage: Ensure your mower’s system voltage matches (typically 18V for these models).

Key Things to Know

• Low user rating (2.5/5): Only 4 reviews, so reliability data is thin. Some users report shorter runtime than OEM or early failure.
• Installation difficulty: Easy – remove old battery, disconnect plug, connect new battery, secure in compartment. No soldering or tools required beyond a screwdriver for the cover.
• Capacity vs. OEM: 5200mAh is standard for these models, but aftermarket cells may degrade faster than Husqvarna’s original.
• Warranty risk: Using a non-OEM battery may void your mower’s warranty if still active. Check before buying.

Should You Buy It

Only buy this if you need a low-cost, quick replacement and are comfortable with potential shorter lifespan or performance inconsistency. If you want guaranteed reliability and longer runtime, spend more on an OEM battery.
