Cut your aircraft battery weight and increase your useful load. The TB14 is designed for smaller, 28-volt fixed wing aircraft. You’ll gain faster and cooler engine starts and benefit from superior performance in extreme temperatures (-20°C to +70°C). The TB14 features built-in charge current limiting to protect your aircraft's alternator or generator without needing to install additional equipment and delivers cockpit communication via RS-232 (analog and discrete signals). This lithium-ion aircraft battery is TSO certified, lasts 8 years and features on-condition maintenance, saving you time and money.

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. Turboprop engines, like the Pratt & Whitney PT6A, start in half the time and, typically, 100° cooler. Our sophisticated design ensures your aircraft outperforms all others in extreme temperatures, from -20°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 maintenance-free aircraft batteries on the market. The TB14 requires no capacity checks and last 8 years. That’s up to 4x longer than lead acid and NiCad.
