Reduce your aircraft battery weight by up to 40 pounds per battery and increase your useful load. The True Blue Power Gen5 TB40 Lithium-ion Aircraft Battery is TSO certified, features a built-in automatic heater and allows you to fully recharge within 30 minutes. This intelligent battery is engineered with a Built-in Test (BIT) indicator to communicate real-time state-of-change and state-of-health data, on demand.
True Blue Power batteries are the lightest and most compact, saving you up to 85 pounds per battery. Our efficient design gives you more power per pound than any other aircraft battery. Less weight means more passengers, more cargo, more fuel, and more design flexibility.
True Blue Power batteries give you cooler and faster engine starts, capable of 7 starts in 7 minutes. Turboprop engines, like the Pratt & Whitney PT6A, start in half the time and, typically, 100° cooler. Our sophisticated design allows your battery to fully recharge within 30 minutes and constant voltage helps eliminate hot starts. An automatic, built-in heater ensures your aircraft outperforms all others in extreme temperatures, from -40°C to +70°C.
True Blue Power batteries provide constant monitoring, protection, and capacity data. Our proprietary Battery Management System is exclusive to True Blue Power and has been validated by the most demanding aircraft manufacturers. Even smarter, you’ll save time and money with the longest-lasting, maintenance-free aircraft batteries on the market. Gen5 batteries require no capacity checks and last 8 years. That’s up to 4x longer than lead acid and NiCad.
