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.
