Page 3: Overview - Purpose
The EarthX Lithium battery is designed as a maintenance free replacement for 12-volt lead- acid or lithium starter batteries. The ETX900-TSO battery is part of the electrical system as a Secondary function with the Alternator system being Primary in the aircraft electrical system. - Page 4 E T X T S O L I T H I U M B A T T E R I E S a. The maximum charge rating is 80 amps, so the aircraft alternator rated output must be 80 amps or less. b.

ICA via the customer’s email of record. Battery Maintenance Requirements The ETX900-TSO battery is a maintenance free battery with no internal replaceable components. No inspection or testing is required for the first 24 months after purchase. Thereafter, an annual inspection is required to ensure that the battery functions as designed and installed for safe operation of the aircraft. - Page 7 E T X T S O L I T H I U M B A T T E R I E S 3) Ensure the battery is fully charged. Turn off the aircraft master switch and any other battery loads, then measure the voltage at the battery terminals. A fully charged battery should be 13.4 volts or greater.

This table shows typical charging times for the battery: Model Charging Amps Charging Time ETX900-TSO 5 amp (TM291 Charger) 3 hour 10 amp (TM275) 1.5 hour Lithium batteries have a very low self-discharge rate which means the battery, if disconnected from the aircraft, could “hold its charge”... -
Page 9: Battery End Of Life
For maximum battery and starting system life, do not crank an engine for more than 15 seconds within any 1 minute period. Battery End of Life The ETX900-TSO battery expected life is 6 years. However, the following conditions indicate battery end-of-life and the battery shall be replaced to ensure continued airworthiness: ... -

Will not hold a charge (>13.2 volts a week after charging the battery to full charge) 6 years of in-aircraft service At battery end-of-life contact EarthX for replacement options. Batteries can be recycled at any location accepting lithium ion type batteries. Drain battery and or cover terminals with electrical insulating tape prior to recycling. -
Page 11: Normal Operation
E T X T S O L I T H I U M B A T T E R I E S Normal Operation Under normal operating conditions the battery performs as any lead acid battery, storing energy from the charging system and suppling it when the charging system is off. Abnormal Operation If the battery fault indicator LED turns on and remains on solid, it is an indication that the BMS electronics has failed. -
