Description

Product Description

Save time and money with longer battery life and no required capacity checks. The TB28-12V, designed for 14-volt aircraft, lasts 8 years and offers on-condition maintenance. You’ll benefit from cooler, faster engine starts and superior performance in extreme temperatures (-20°C to +70°C). This intelligent lithium-ion battery 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.

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. 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 TB28-12V requires no capacity checks and last 8 years. That’s up to 4x longer than lead acid and NiCad.
