Saves You Money

1 NX1K Battery = x4 Traditional Lead

Investing in lithium phosphate compared to routinely replacing lead batteries and associated service costs provides a positive return on investment across the NX1K range, therefore saving you money. 

Runs Longer

Increased runtime of up to 44% compared to lead batteries

Configurable performance that suits you, ensuring you can keep cleaning when it is most convenient for you.

*Any comparisons used are based on typical usage scenarios, results may differ. Performance comparisons use equivalent GelTec models. 


Fast & Flexible Charging

NX1K Fast Charge Technology drives productivity, providing you and increase in machine availability in comparison to Lead.

Unlike Lead, NX1K Fast Charge Technology allows completely flexible charging, allowing you to use your machine whenever you need to, no matter how much it’s charged. 

  • Battery can be used partially charged without compromising capacity
  • Chemical stability prevents overheating

Example: 4045/6055T/8072 x 2 Battery Configuration

More Sustainable

Divert waste from landfills with a longer lasting battery containing no toxic, heavy metals.

NX1K contains no toxic, heavy metals and lasts longer than lead alternatives, significantly reducing material use and disposal, providing a much more sustainable solution. Made to last, the NX1K are rated for 4000 charge cycles with the expectation of lasting at least 8 years which reduces the need for frequent battery replacements and battery disposal.


8 Year Warranty

NX1K is guaranteed to last longer!

Utilising the latest Lithium Phosphate Technology and delivering over 4000 charge cycles, NX1K is one of the safest batteries platforms on the market. An 8-year battery warranty provides complete peace of mind for you and your cleaning fleet.

  • Expected 10 years of life
  • 4000 charge cycles
