Husqvarna Automower Battery Problems - Short Runtime

Common Medium Difficulty High Cost 10-60 Minutes
← Back to Overview
Problem: The battery only lasts a short time (less than 30-60 minutes instead of the normal 70-240 minutes). The mower constantly returns to the charging station, barely manages any area, and the "Empty battery" error message appears frequently.

Problem Description

The battery only lasts a short time (less than 30-60 minutes instead of the normal 70-240 minutes depending on model). The mower constantly returns to the charging station, barely manages any area, and the "Empty battery" error message appears frequently. These are typical signs of battery aging, which is normal after 2-4 years of operation.

Affected Models: All models after 2-4 years of use (normal battery lifespan)

Possible Causes

  1. Battery aged (normal aging after 2-4 years) – Most common cause in older mowers
  2. Battery not stored correctly in winter – Frost damage or deep discharge
  3. Deep discharge damaged battery – Not charged for too long
  4. Rolling resistance too high – Dirty wheels or dull blades increase power consumption
  5. Large work area with many obstacles – Significantly increases energy consumption

Step-by-Step Solutions

Solution 1: Test Battery Condition

Time Required: 10 minutes

  1. Let the mower charge completely
  2. Time the mowing until return to charging station
  3. Compare with normal values (see your model's manual):
    • 305, 310: approx. 70 minutes
    • 315, 320: approx. 90 minutes
    • 420: approx. 120 minutes
    • 430X, 440: approx. 140-160 minutes
    • 450X: approx. 200-240 minutes
  4. If significantly below 50% of normal time: Replace battery
App Check: In the Automower Connect app under "Statistics" you'll find the average mowing time. This is a reliable method to assess battery condition.

Solution 2: Reduce Power Consumption

Time Required: 20-30 minutes

  1. Thoroughly clean cutting deck, wheels, and chassis
  2. Replace all 3 blades simultaneously (dull blades increase consumption by up to 30%!)
  3. Clean the charging contacts for optimal charging
  4. Check tire pressure and wheel condition
  5. If necessary, reduce work area or increase mowing times
Tools Needed: Brush, original blades (3 pieces), screwdriver, cloth
Tip: Dull blades are often overlooked. They not only lead to poor cutting results but also massively increase power consumption. Change blades every 2-3 months for optimal efficiency.

Solution 3: Replace Battery (for Advanced Users)

Time Required: 30-60 minutes

ONLY use original Husqvarna batteries!

  1. Turn off the mower and ensure it's disconnected from power
  2. Remove the housing cover (model-specific)
  3. Carefully disconnect the battery connector (observe polarity!)
  4. Remove the battery mounting screws
  5. Insert the new battery (same type!)
  6. Connect the plug (correct polarity!)
  7. Remount the housing
  8. Perform the first charging cycle (charge completely)
Tools Needed: Screwdriver set, Allen keys (depending on model), original battery
Important: Use ONLY original Husqvarna batteries! Cheap replacement batteries can:
• Damage the mower
• Void the warranty
• Present fire hazard
• Have significantly shorter lifespan

Old batteries must be disposed of properly (electronic waste/battery collection)!

When Should You Consult a Professional?

Battery replacement is feasible for most models but requires some technical skill. Professional help can be useful the first time. For uncertainties or complicated models (e.g., 500 series), better consult a specialist. We offer professional battery replacement with original batteries and 2-year warranty.

Preventive Measures

  • Winter storage done correctly – Store battery fully charged and frost-free (10-20°C ideal)
  • Avoid deep discharge – Recharge every 2-3 months even in winter
  • Avoid temperature extremes – Don't operate below 5°C or above 45°C
  • Regular cleaning – Clean mower = less power consumption
  • Use original batteries – Cheap replicas last significantly shorter
  • Charging station in shade – Overheating shortens battery life
  • Replace blades regularly – Every 2-3 months for optimal efficiency
Pro Tip: Battery life depends heavily on storage. Store the mower in winter at 50-70% charge in a cool, dry place (10-15°C). Fully charged batteries at high temperatures age faster. Recharge once during winter to avoid deep discharge.
