Husqvarna 430765 Lawn Mower Battery Genuine Original Equipment Manufacturer (OEM) part

What It Is

The Husqvarna 430765 is a genuine OEM 12V, 17Ah sealed lead-acid (SLA) battery designed to power the electric start and electrical systems on select Husqvarna riding lawn mowers and zero-turn models. It’s a direct replacement for the factory battery, not a universal or aftermarket option.

Fitment & Compatibility

Before buying, verify three things:

• Model number: This battery fits specific Husqvarna models, including many L series (e.g., LGT2654, LTH2454) and Z series (e.g., Z242F, Z254) mowers, plus some Craftsman and Poulan Pro units built on the same platform. Check your owner’s manual or the battery tray label for part number 430765.
• Dimensions: The battery measures approximately 7.7” long x 5.1” wide x 6.2” tall. Measure your existing battery tray—if it’s smaller or a different shape, this won’t fit.
• Terminal orientation: It uses standard SAE posts (positive on the right when facing the battery). Confirm your cables reach without stretching or reversing polarity.

Do not assume “Husqvarna battery” means universal fit—many models use different sizes or CCA ratings.

Key Things to Know

• Quality & longevity: As an OEM part, it matches factory specs and typically lasts 3–5 seasons with proper charging. Aftermarket batteries may cost less but often have lower cold cranking amps (CCA) and shorter life.
• Installation difficulty: Easy—disconnect negative first, swap cables, secure hold-down. No programming or special tools needed. Expect 15–20 minutes.
• Common gotchas: This is a wet lead-acid battery—it may arrive dry and require filling with acid (included) and a 2–4 hour initial charge. Do not install a dry battery; it can damage the mower’s electrical system.
• Charging: Use a low-amp (1–2A) maintainer during storage. A dead battery left discharged can sulfate and fail prematurely.

Should You Buy It

Buy this if you own a compatible Husqvarna mower and want a guaranteed fit with factory reliability. Skip it if you’re on a tight budget—aftermarket equivalents (like a U1-7 battery) cost about $30–40 less, though you risk slightly shorter life or fitment issues. For most owners, the peace of mind of OEM is worth the premium.
