GREEN90
The first and only lithium-free ULB in the aviation market.
Innovative: The green power source.
The GREEN90 Underwater Locator Beacon developed by NOVEGA is equipped with a battery which meets the 90-day requirement of TSO-C121b and does not contain any lithium.
The alkaline battery in the GREEN90 is as reliable in performance as any lithium battery. It convinces with its enormous advantages as the beacon itself and the battery is not declared as dangerous goods. The guidelines for integration, handling, transportation and disposal are enormously simplified compared to the strict guidelines for lithium powered devices.

The GREEN90 key facts:
Corrosion-resistance
A new formulated coating topped the already excellent corrosion protection. Hence the GREEN90 withstands the extreme environmental conditions on sea even longer. Approved in long term testing and guaranteed by us.
RoHS and REACH
The GREEN90 meets the conformity of Directive 1907/2006 EU, 2011/65/EU and 2015/863/EU of the European Parliament and of the Council on the restriction of the use of certain hazardous substances in electrical and electronic equipment.
Form and Fit
The design and geometry of the GREEN90 are exactly the same as those of all ULB in the market. Your advantage: Conversion to the GREEN90 is possible immediately and without any conversion measures for mounting on Flight Data Recorders and Cockpit Voice Recorders.
Cut costs – raise value
Expense and time are money – and with the GREEN90 you save money right from the start. The efforts for obtaining transport permissions, dangerous goods surcharges, additional insurances and complex shipping instructions are completely eliminated.
Frequently asked questions about the GREEN90
Our answers for you
Novega has tested all conceivable alternatives. Alkaline leads in 5 central points:
- Certifications: FAA and EASA special conditions and ETSO/TSO C142b do not apply
- Safety and handling: Non-hazardous, non-combustible, no explosion hazard
- Thermal outliers: There are no thermal runaway conditions
- Transport: No transport restrictions
- Disposal: Simplified disposal guidelines compared to lithium
Definitely, because the efforts for obtaining transport permissions, dangerous goods surcharges, additional insurances and complex shipping instructions are completely eliminated.
No. If the alkaline battery is operated in the intended temperature range, the chemistry does not change. The thermocycling test for a full life cycle showed that temperature variations do not alter the internal resistance, battery voltage and functionality of the cell.
Alkaline batteries tend to leak at low pressure, in uncontrolled environments and when discharged. NOVEGA constructively excludes these conditions:
- The cell is hermetically sealed. This prevents a drop in pressure and pressure fluctuations.
- Due to the high energy density and a shelf life of 8 years, a low-voltage operating condition is virtually impossible.
- Several insulation layers guarantee a hermetically sealed housing and reliably prevent cell leaks.
To select the alkaline cell for the GREEN90, we tested a wide range of high performance cells from various manufacturers. All products were of industrial quality. The selected alkaline cell has the best performance with excellent properties in terms of voltage stability, vibration and shock resistance, temperature stability and power density.
NOVEGA's GREEN90 is tested to the latest ETSO-C121b and has been fully approved since February 2019.
