Battery for Husqvarna Automower 320 2013, Automower 320 2014, Automower 320 2015, Automower 330X 2014, Automower 330X 2015, Automower 420 2016, Automower 550H 2019, Automower 593 8000mAh / 144.0Wh

What It Is

This is a 8000mAh / 144.0Wh replacement lithium-ion battery specifically designed for Husqvarna Automower robotic models: 320 (2013-2015), 330X (2014-2015), 420 (2016), and 550H (2019). It powers the mower’s cutting motor, navigation, and charging cycles.

Fitment & Compatibility

Before buying, verify your mower’s exact model year—Husqvarna changed battery connectors and shapes between years. Check the original battery part number (e.g., 579 84 45-01 or 590 79 50-01) printed on your current battery. This 8000mAh unit is a direct OEM replacement for those listed models, but it will not fit the 320/330X before 2013 or the 420 after 2016 without adapter modifications. Measure your battery compartment: this battery is ~150mm x 90mm x 70mm. If your mower uses a different connector (e.g., 2-pin vs. 3-pin), it won’t work.

Key Things to Know

• Quality concern: The 1.0/5 star rating (1 review) suggests possible early failure, poor runtime, or fit issues. Verify return policy before purchase.
• Installation: Easy—remove old battery, disconnect plug, snap in new one, and charge fully (8-12 hours) before first use. No tools needed.
• Common gotcha: If your mower is older than 2013 or newer than 2019, this battery likely won’t fit. Check the sticker on your mower’s underside for the exact model year.
• Performance: 8000mAh should provide ~60-90 minutes of cutting per charge, but actual runtime depends on grass thickness, terrain, and mower age.

Should You Buy It

Only buy this if you own one of the exact models listed (320 2013-2015, 330X 2014-2015, 420 2016, 550H 2019) and your current battery is dead. Given the single poor review, consider a higher-rated aftermarket alternative (e.g., from Greenworks or PowerSmart) that matches your mower’s part number and offers better warranty support. If you must have OEM, this is your only option, but manage expectations on longevity.
