Battery Maintenance
Well, we had some really hot spots (120°) and some altitude (>10K feet) this summer. So I thought I would do a little battery check and maintenance. First thing I noticed is that there was a stain on the top of the battery. So I pulled the batteries and started by cleaning them up.

Batteries one before and one after clean up
Good news - the stain turned out to be ATF from my (evidently clumsy) once every two year flush of the PowerGear hydraulic fluid. However bad news is that the front restraining strap buckle had broken, and one of the batteries was tilted in the tray. A trip to ace and I had some thicker / wider webbing and a more sturdy strap buckle.

Topped up all the cells and then put the batteries back in.

All done!
I remain very happy with the "diagonal" connection of the coach batteries. (See my previous post.) The water loss issue is solved. I am getting better battery charge and life. Now if I just went to AGM....

Procedure:
-1) Remove wedding ring and watch
0) Put on safety glasses / gloves
1) Lay out plastic to rest batteries on
2) Hit coach battery disconnect (Off) - verify dc lights off
3) Disconnect Negative Lead
4) Disconnect Positive leads
5) Remove batteries and clean
6) Open ports and clean edges
7) Add water to cells as needed
8) Replace batteries and strap down
9) Reconnect positive leads and tighten
10) Double check polarity
11) Reconnect negative leads and tighten
12) Triple check polarity and connection
13) Hit coach battery disconnect switch (On)
14) Verify DC lights operate and check charge wizard
15) Remember to put wedding ring back on!
