New task learned! Battery fluid testing

So I learned another new task at our flying club's maintenance day this month! How to test the fluid level in the C182's battery.

I volunteered to do this routinely, as I am small enough to fit all folded up in the baggage compartment area and thus reach the battery in the tail behind baggage easier than the guys who have to dangle lots of legs out the baggage door!

We test in 2 ways:

1. With a flashlight and an angled mirror, to see in each battery post/well, and see that the fluid goes up the sides a bit, and has that nice look of viscosity and surface tension (hard to put in words, but easy enough to see!), and also
2. Using the floating ball (well, tube) type hydrometer - looks like a turkey baster with a measured off tube inside - have to squeeze the air out with the bulb, and carefully let the fluid up

Key is not to get this acidic fluid on yourself or the carpet!

It was pretty fun!
