Dennis E-Series battery mowers are designed to give grounds teams, contractors and local authorities the performance they expect from Dennis, with the added benefits of quieter operation, reduced emissions and lower running costs.
At the heart of every E-Series machine is a custom-built battery system, developed specifically for Dennis mowing applications.
From cell selection and module creation to battery casing and Battery Management System, each element has been designed to deliver reliable power, long run time and consistent cutting performance.
The E-Series batteries use high-density NMC cells, carefully selected to provide more hours of operation between charges. This supports longer run hours in daily use, helping teams cover more ground from a single charge and reducing the need to stop work for battery changes or extended recharging.
With a full recharge time of less than two hours, machines can be returned to service quickly, supporting busy maintenance schedules across sports grounds, cemeteries, schools, parks and amenity spaces.
Reliability is central to the Dennis approach. Precision laser welding, plasma cleaning and heat-staking support strong, durable battery construction, while the intelligent Battery Management System helps optimise performance, battery longevity, power management, heat management and safety.
Each battery is UKCA certified and rigorously tested for shock, vibration, thermal extremes, humidity, altitude and cycling. Every unit also carries a unique serial number for full traceability and quality assurance.
With low hand-arm vibration, reduced noise and superb aftersales support as standard from Dennis, the E-Series range offers a practical, professional route to battery-powered turf maintenance without compromising on finish, performance or confidence.
