Husqvarna 583629801 Lawn Mower Battery Kit (Replaces 431157, 580985901) Genuine Original Equipment Manufacturer (OEM) Part

What It Is

This is a genuine OEM battery kit for Husqvarna robotic lawn mowers, providing the power source needed for autonomous mowing operation. It replaces older part numbers 431157 and 580985901, designed specifically for Husqvarna’s Automower line.

Fitment & Compatibility

Before buying, verify your mower model. This kit fits Husqvarna Automower models 305, 308, 310, 315, 315X, 420, 430X, 440, 450X, and 520. Check your mower’s model number (on the chassis or user manual) and confirm it uses a 7.2V NiMH battery. Measure the battery compartment dimensions (approx. 4.5 x 2.5 x 1.5 inches) to ensure physical fit—older or non-Husqvarna models may differ. This is an OEM part, not aftermarket, so compatibility is guaranteed for listed models, but avoid using in third-party or modified mowers.

Key Things to Know

• Quality & Lifespan: Genuine Husqvarna batteries typically last 2-3 seasons with proper care; aftermarket alternatives may degrade faster or cause charging errors.
• Installation Difficulty: Easy—requires removing the mower’s top cover, unplugging the old connector, and swapping the battery. No special tools needed, but disconnect the mower from power first.
• Common Gotchas: This is a NiMH battery, not lithium-ion. Don’t charge it with a lithium charger. Also, if your mower has sat unused for months, the battery may be deeply discharged; try a slow charge before replacing.
• Price vs. Value: At ~$74, it’s mid-range for OEM; cheaper aftermarket options exist but risk compatibility or shorter life.

Should You Buy It

If you own a compatible Husqvarna Automower and want reliable, drop-in replacement without warranty or compatibility worries, this OEM kit is a solid choice. It’s best for owners who prefer genuine parts over risking aftermarket issues—especially if your mower is still under warranty or you need a quick, no-hassle fix. For budget-conscious users or older mowers, a tested aftermarket battery may save money, but check reviews carefully.
