The Cyclon 2V-J: Battery 2V Single Cell range and AGM technology
The Battery 2V Single Cell is the Cyclon range the 2V-J belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.
In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.
Why choose Cyclon batteries
Cyclon cells and monoblocs are the reference when the application demands power, vibration resistance and reliability in extreme conditions. All the Cyclon batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
Official warranty
The Cyclon 2V-J comes with the manufacturer's official warranty against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you.
How to make it last longer
Replace all the batteries in the set at once and avoid environments continuously above 25 °C. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.
