🌿 How to Choose the Best Cordless Lawn Mowers UK
When choosing the best cordless lawn mowers UK there are a few things you need to consider:
1. Match the size of your lawn
Small (<150 m²) → Einhell or Bosch CityMower
Medium (150–300 m²) → Worx WG737E
Large (300–500 m²) → Makita DLM432Z
2. Check battery capacity (Ah)
Higher Ah = longer run-time.
3. Look for shared battery systems
They save money later when you buy other tools.

Do cordless mowers work on damp grass?
They can, but you’ll get the best results once the lawn surface is mostly dry. Wet grass drains batteries faster and can clog the blades.
How long do the batteries last?
Most modern lithium packs provide 30–45 minutes per charge and last 3–5 years with proper care.
Can I use third-party batteries?
Some brands allow it, but genuine packs usually provide better performance and safety.
Can a cordless mower cut long grass?
Yes, but it’s best to raise the cutting height first and mow in stages. Most cordless models cope well if the grass isn’t damp or over 15 cm long. For overgrown lawns, a strimmer pass first helps prevent clogging.
How long do cordless mower batteries take to charge?
Fast chargers can recharge a typical 4.0 Ah battery in 60–90 minutes. Slower chargers can take up to three hours. Many gardeners keep a spare battery so one can charge while the other is in use.
Are cordless mowers powerful enough for large lawns?
Modern 36–40 V systems such as Worx PowerShare and Makita LXT easily handle 300–500 m² gardens. The key is using high-capacity batteries (4.0 Ah or higher) and keeping blades sharp for efficient cuts.
Can I mow on a slope with a cordless mower?
Yes — cordless models are generally lighter than petrol ones, so they’re easier to push uphill. Always mow across a gentle slope rather than directly up or down for better traction and safety.
Can I leave lithium batteries on the charger?
With modern smart chargers it’s safe, but long-term storage is best at ~40–60% charge in a cool, dry place.
Do cordless mowers mulch and is mulching good for UK lawns?
Many have a mulching plug. Mulching returns fine clippings as fertiliser, helping moisture retention—useful in hosepipe bans.
How many square metres can a 4.0Ah battery mow?
Rough guide: ~100–150 m² per 18–20V 4.0Ah pack in average conditions. Wet/long grass reduces this; sharp blades increase it.
