About Cordless Lawn Mowers
Battery voltage is the headline number, but Ah (battery capacity) and motor type matter more in practice. A brushless 36V motor with a 4Ah battery is the sweet spot for most UK gardens — enough for around 350 m² per charge.
Twin-battery 2x18V mowers from Makita, DeWalt and Bosch let you reuse batteries across your wider tool kit. EGO's 56V Arc Lithium platform is the most powerful consumer cordless system you can buy.
Look for a brushless motor (longer life, more torque), a 6+ position height-adjust lever, mulching plug, and a 50-litre+ grass box on decks over 40 cm. Steel decks are worth the upgrade if you mow weekly.
