Do you have a newer or updated aircraft that is equipped with the Garmin G1000 series avionics package? We do capacitance tests on their standby batteries as well.
Is your aircraft equipped with the Mid-Continent standby ADI electric gyro? We can perform a capacitance test on its battery too!
If you have a battery, we can probably test it! Give us a call to discuss your electrical power needs.

Testimonials
We are Oklahoma City's longest established general and corporate aviation maintenance facility. We get the job done.
No one touches my airplane except Ed Schwartz & E.T. Mechanical. Why? Because as an instrument pilot, Ed understands how important it is to have complete confidence in your “Bird’ before you launch. They do the job right.
We’ve been using E.T. Mechanical for about 30 years. Being in the aircraft sales and management business, specializing in Citations and King Airs, I’ve used many maintenance facilities. Without question, E.T. Mechanical is simply the best by far.
Out of all of the shops I have Used over my 25+ years of corporate aviation, nothing compares with the level of service and quality of the workmanship than E.T. Mechanical.
Their attention to detail and quality control is the best in the industry.
As the owner off Touchdown Aviation LLC, I rely on ET Mechanical for battery capacitance testing on our Learjets. Their team is always professional, timely, and delivers top-notch service every time. I have complete confidence in their work, and I'm always impressed by their attention to detail and expertise. I highly recommend them!
