Built for the Field

The Harrier is the latest 12 volt battery to be added to ATSI's already large range of Ni-MH rechargeable batteries. Covering all areas of deployment from the Arctic through to the Tropics, the Harrier is totally submersible to a depth of 2 metres in either fresh or seawater without damage to internal electronics. A four-segment LED display shows the state of charge at any time via a press-to-test button. With a guaranteed minimum cycle life of 600 recharges, the Harrier is a very cost-efficient battery suitable for the Military, Law Enforcement Agencies, Scientific Research Establishments, Motor Sports, Petrochemical Industries, and the Film and Television Industry.

💧

Submersible to 2 Metres

The Harrier is totally submersible to a depth of 2 metres in both fresh and seawater without damage to internal electronics — ideal for river crossings, amphibious operations, and sustained wet-weather deployments.

🌡️

Arctic to Tropical Operation

Designed to cover the full range of climate zones from Arctic environments to tropical theatres, the Harrier delivers consistent performance wherever the mission takes it.

🔋

State of Charge Display

A four-segment LED display shows the battery state of charge at any time via a simple press-to-test button, giving operators an instant readiness check in the field.

♻️

600+ Cycle Guarantee

A guaranteed minimum cycle life of 600 recharges makes the Harrier an exceptionally cost-efficient battery for long-term operational programmes and sustained deployment.

🏭

Multi-Sector Applications

Suitable for Military, Law Enforcement Agencies, Scientific Research Establishments, Motor Sports, Petrochemical Industries, and the Film and Television Industry.

Fully Submersible

Unlike most battery systems, the Harrier can operate while partially or fully submerged to 2 metres in fresh or seawater — opening up a wide range of covert and amphibious applications.

Cost-Efficient Long Term

A guaranteed minimum cycle life of 600 recharges makes the Harrier far more cost-effective than primary battery alternatives over the lifetime of an operational programme.

From Arctic to Tropics

Tested globally, this product covers every area of operations without performance compromise in any climatic zone.

Arctic

Sub-Zero Arctic Operations

Designed for operation from sub-zero Arctic conditions, the Harrier delivers consistent performance in the extreme cold environments of Northern Europe, Canada, and mountain operations.

Tropic

Desert & Tropical Environments

Equally capable in tropical heat, the Harrier operates reliably across the full range of global deployment theatres without performance degradation in high ambient temperatures.

2m IP

Submerged & Wet Conditions

Totally submersible to 2 metres depth in both fresh and seawater. Ideal for river crossings, beach landings, and sustained monsoon operations.

NBC

Chemical & Contaminated Environments

Ni-MH construction provides resilience against chemical contamination, with the ability to be decontaminated externally without risk to the battery internals.
