QUESTIONS & ANSWERS

Question:
Can I partially charge my Gill 7638-44 battery today and finish charging it tomorrow?
Answer:

Yes. Gill aircraft batteries do not have any “memory effect,” so interrupting the charge will not harm them. Just be sure to turn off your battery charger when pausing the process. For optimal performance, it’s best to finish charging your battery within the same day.

Asked January 13, 2025
Question:
Can I charge my Gill 7638-44 battery while the aircraft is on the ground?
Answer:

Gill does not recommend onboard battery charging. Always remove the battery from the aircraft before charging.

Asked January 13, 2025
Question:
How often should the Gill 7638-44 battery be changed?
Answer:

If properly serviced, your battery can provide several years of reliable service. However, Gill recommends changing your battery every two-and-a-half to three years.

Asked January 13, 2025
Question:
What is good battery voltage on a new, fully charged Gill 7638-44 battery?
Answer:

On a newly charged 24V battery like the 7638-44, the voltage should read 26 to 26.4 volts.

Asked January 13, 2025
Question:
How should I store my Gill 7638-44 battery when not in use?
Answer:

Store the battery in a cool, dry place with a stable temperature, ideally around 80°F (27°C). Avoid areas with high humidity or extreme temperatures, as these conditions can adversely affect the battery’s health. Ensure the storage area is well-ventilated and away from flammable materials. Additionally, store the battery in an upright position to prevent any potential leakage.

Before storage, wipe the battery with a dry cloth to remove any dirt or moisture that could lead to terminal corrosion and ensure the battery is fully charged. A fully charged battery is less susceptible to sulfation, a condition that can diminish performance. Even during storage, it’s important to check the battery’s voltage periodically. If the voltage drops below 75% of its state of charge, recharge the battery to prevent deep discharge, which can shorten its lifespan.

Asked January 13, 2025
Question:
Can the Gill 7638-44 battery be used in cold temperatures?
Answer:

Yes, the battery is designed to perform in low-temperature environments, with specific cold cranking performance metrics provided for temperatures as low as -30°C (-22°F).

Asked January 13, 2025
Question:
What is the shelf life of the Gill 7638-44 battery?
Answer:

Gill 7000 Series LT valve-regulated lead-acid batteries, including the 7638-44, can be stored for up to 24 months without an inspection if stored between 40°F and 80°F.

Asked January 13, 2025
Question:
Does the Gill 7638-44 battery need to be charged upon receipt?
Answer:

Gill 7000 Series LT valve-regulated lead-acid batteries are shipped fully charged and ready for installation. However, it’s advisable to verify the battery’s state of charge upon receipt to ensure optimal performance. If the battery has lost charge during transit or storage, recharging it before installation is recommended.

Asked January 13, 2025
Question:
What is the warranty on the Gill 7638-44 battery?
Answer:

Gill 7000 Series LT valve-regulated lead-acid batteries are warranted for a period of 12 months or 600 hours of operation, whichever occurs first after the date of installation. Teledyne Battery Products (TBP) will replace, at no charge, any battery manufactured or supplied by it which, within the applicable 12 months or 600-hour period, is found to the satisfaction of TBP to be defective in material or workmanship.

Asked January 13, 2025
Question:
Is the Gill 7638-44 battery truly maintenance-free?
Answer:

While the battery is sealed and requires less maintenance than traditional flooded lead-acid batteries, regular inspections and capacity checks are recommended to ensure continued airworthiness.
