Cut your aircraft battery weight by up to 45% with the True Blue Power TB17 Advanced Lithium-ion Aircraft Battery. You’ll protect your engine with cooler, faster starts. An automatic, built-in heater ensures your aircraft outperforms all others in extreme cold temperatures, from -40°C to +70°C. The TB17 is TSO certified and has a 2-year maintenance interval, saving you time and money.
Get started with certified lithium-ion aircraft batteries
Start Lighter
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.
Start Faster
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.
Start Smarter
True Blue Power batteries feature charge current limiting, overcharge, over-discharge, over-current, short circuit, over-temperature and under-temperature protection. Even smarter, you’ll save time and money with the longest-lasting aircraft batteries on the market. True Blue Power batteries last 8 years. That’s up to 4x longer than lead acid and NiCad.
