True Blue Lithium-Ion Batteries
The True Blue Power Advanced Lithium-ion Batteries use the most sophisticated lithium-ion chemistry available, providing aviators with the unmatched advantage of faster starts, increased power, reduced weight, extended useful life, and lower direct operating costs.
Product CardUpgrade Benefits
- Higher voltage during engine start leading to less wear, less maintenance, and increased useful life
- Faster engine starts – 7 starts in 7 minutes – and only 15 minutes for a complete recharge when the battery is fully discharged on a typical aircraft.
- Superior high and low temperature performance (-40°C/-40°F to +70°C/158°F)
- Delivers 3x the energy per kilogram when compared to lead-acid and nickel-cadmium cells
- Protection against overcharge, over-discharge, over-current, short circuit, over-temperature, and under-temperature
- Reduced maintenance costs
- 8-year average useful life
- For single battery applications, increased useful load between 29 and 32 lbs.
- For dual battery applications, weight savings of up to 120 lbs.
Technology
- TB40 Capacity: 40 amp-hour nominal (at 23°C/73°F)
- TB40 Weight: 36.6 lbs. (up to 60% less than lead-acid and NiCad alternatives)
- Advanced NanoPhosphate® lithium-ion cell chemistry from A123 Systems, LLC – offering 3 times the energy per kilogram, resulting in a battery that is 40% lighter than lead-acid or nickel-cadmium alternatives
- Built-in automatic internal heater
- Maintenance: 2-year maintenance interval; offers 50-90% savings on maintenance costs
- Warranty: 2-year limited
Dual Lead-acid Battery System
Finnoff Aviation Products has obtained FAA approval for a dual lead-acid battery system for Pilatus PC-12/45 and PC-12/47 aircraft.
- Can Supply Power for 45 Minutes if the Load Is Reduced Below 50 Amps
- Allows for Much Higher Remaining Battery Capacity After “Dry Motoring” Greatly Improving the Likelihood of a Good Start
- Dual RG-380E/44 Batteries Increase Starting Power (Watts) by About 25%. Dual RG-380E/60L Batteries Yield About 50% More Starting Power vs. a Single RG-380E/44
- Greatly Increases the Likelihood of a Successful Engine Start in Extreme Cold
- The Concorde RG380E/44 and RG380E/60L Batteries Are Both Approved for This Installation
Batteries
The Concorde RG380E/44 and RG380E/60L batteries are both approved for this installation. Only these Concorde lead acid batteries are acceptable.
| Capacity (amp-hours) | IPR Power Rating (23C) | IPP Power Rating (23C) | Weight (lbs) | |
|---|---|---|---|---|
| RG-380E/44 | 44 | 1000A | 1350A | 86 |
| RG-380E/60L | 48 | 1200A | 1600A | 96 |
Sales
The dual battery kit is only available through authorized Pilatus Service Centers. Suggested retail price, not including batteries, is $41,080.00. Batteries can be purchased from the Service Centers and Service Center installation charges will apply.
In the event of an engine failure, or dual generator failure, the single battery PC-12 can supply power for 20 minutes if the load is reduced below 60 amps. The Finnoff Aviation Products Dual Battery System will double, or more than double, the time you have with electrical power to deal with your emergency and land safely; up to 45 minutes of electrical power with the high capacity RG380E/60L option (68 minutes if the load is reduced below 50 amps).
During rapid “turn-around” of an aircraft in hot weather it may be necessary to “dry motor” the engine prior to start-up for the next leg of your journey. This process involves turning the engine, using only battery power, in order to force cooling air through it. Unfortunately, “dry motoring” the engine can deplete the battery to the point that it doesn’t have sufficient energy left for an efficient start once fuel is introduced. This can cause the exact problem you were trying to avoid – a hot start or aborted start. Our Dual Battery System allows for much higher remaining battery capacity after “dry motoring”, greatly improving the likelihood of a good start.
The Dual Battery System provides higher starting power leading to faster, therefore cooler, engine starts. This prolongs engine life. Dual RG-380E/44 batteries increase starting power (watts) by about 25%. Dual RG-380E/60L batteries yield about 50% more starting power vs. a single RG-380E/44.
The higher capacity and higher starting power provided by the Dual Battery System greatly increases the likelihood of a successful engine start in extreme cold.
