Note:   An important Service Reminder is available regarding the standby battery (click here for the Microsoft Word document).

What is the life span on the battery, and how can I tell if it needs replacing?
We recommend a replacement at 3 years. The battery can be easily tested during preflight or en route during normal, level flight conditions by pushing and holding the small button on the face of the instrument. After about one minute, either the "Green Test" light will appear, which means the battery is good; or the "Red Test" light will appear, which means the battery needs recharging or replacement.

A more extensive test may be performed by an FAA-approved facility per a detailed testing procedure. Mid-Continent offers a special automated test box for this service.

Remote mounting the battery in a location subject to extreme temperature variations may dramatically shorten the emergency operation time available for the Attitude Indicator as well as the expected battery lifetime. For optimum battery performance, it is recommended to mount the battery in a temperature-controlled section of the aircraft.

Who can replace the battery? How much is a new battery and where can I buy one?
Replacement can be done in the field with or without removal of the Attitude Indicator. A new battery costs $353. Contact your local avionics or instrument shop or visit www.lifesavergyro.com.

What happens if the battery goes dead?
If the battery is run for one hour or less in a power loss situation, it does have the capability to recharge itself. The gyro can recharge the battery over several hours of operation. Consult the installation manual for more details. If a battery is more than 3 years old and is known to be exhausted or continually fails testing, a replacement should be ordered from a local avionics or instrument shop.

What is the limited warranty on the battery?
The battery has a limited warranty of 12 months or 1200 hours of flight, whichever occurs first.

What is the limited warranty on the Lifesaver?
The new Lifesaver gyro has a limited warranty of 12 months or 1200 hours of flights, whichever occurs first.

Can I use my local instrument shop for non-warranty service?
Yes. Overhaul manuals, special fixtures and parts are available to authorized repair facilities. Better still, the Lifesaver incorporates four decades of research and one of the most innovative designs available. It was designed and tested by top aviation instrument experts so it can provide many hours of service.

What wrench is needed in order to remove/re-tighten the pull to cage knob?
A six fluted spline wrench, .060 size.
