    I remember being a motorhead teenager. We'd diagnose battery issues by jumping the engine. If it would run with the battery disconected the charge system was okay. If it wouldn't jump start with the battery connected and connecting the battery killed a running engine? The battery was bad. The magic behind it wasn't a concern. Making it run was.

    I've been working on things with motors for myself and others for over 50 years. Most folks replace the battery or starter when things don't work. But in my experience over the years 80% or most times things fail to turn over it is just corrosion or a loose conection.

    I'm not sure how several streams of conversation about Earth-X ended up on this thread? The first of them was a reply from me to context from a different thread. It would have arrived here on this thread after I hit "reply with quote" on the other.

    My early, non aviation specific, Earth X is still working great but now it's in my ATV. When the new generation ones for planes came out I decided they were worth upgrading to, even though the first one worked great, winter and summer, one deciding reason was my ATV needed a battery! My 12 year old Oddysey is also still working fine, but is not in a plane, but is used for other small tasks that require a portable source of 12 VDC.

    Odyssey batteries are not as good as they were 5 years ago or so.well.... the non-TSO ones anyway. I used to put them in all my bikes and off road rigs & have had 3 failures in 4 years. all right at the 2 year mark, which is coincidentally the warantee period. the days of expecting them to make 7-8 years are over. the guys at Battery Specialists said the ownership has changed hands and they no longer use the virgin lead.

    I agree, and a large percentage of electrical issues end up being a bad ground--which is also a bad connection.
    Bad connection--battery doesn't get charged, engine won't start, fancy lights won't flash, lights that aren't supposed to flash, now do...

    Odyssey Battery Woes

    ...alright just did my 9th annual inspection with the same SBS J16 installed. Didnít even bother charging it before the annual and it tested at 216 CCA out of an original 220 CCA.

    There is a temperature correction that should be applied when floating at lo temperatures. For 12v nominal batteries it is between .018V to .030V per degree C, depending on vendor. That's a full volt or more reduction at 0 deg F, as the standard batt chg Temp is 77F. Pretty sure I have lost batteries from floating at lo temp with cheap maintainers with no temp correction.
    What's a go-around?

    My J16 is going on 11 years old. Am curious how you figured the CCA of your battery--did you use a newer style resistance tester? I bought one for my cars and am trying to figure out if it's accurate on the J16.

    I use this Carbon pile resistance checker from Harbor Freight. Looks just like the more expensive one Matco sells.

    At the recommendation of a guy who works with this stuff for a living, bought the below. His testing found it to be consistently within +/- 5% of his $1000.00 calibrated bench monster. Itís close enough for my needs and has already found 2 other batteries starting to deteriorate before real signs. https://www.amazon.com/BA7-100-1200-.../dp/B0015PI7A4

    I was asked how I check the Hawker battery with this load meter. The Hawker SBS J-16 is a 16 amp hour battery. You turn the knob to three times the Amp Hour (AH) or 1/2 the Cold Cranking Amps (CCA) and hold that for 15 seconds at which time you get a beep and you look at the DC volt meter and it will give you the battery condition. A brand new SBS J-16 will show 10.6-10.8 amps. There is a scale to factor in temperature as well.**

    I just got my second SBS J16 from Spruce. The first one they sent had good voltage but when my friend checked the CCA, it was only 100. That was after I used my Battery Minder for Odyssey on it too. Sent it back and this one is where it should be. They must make a few bad ones.

    I have two PC-545 batteries - two years old. One shows signs of weakness, but it could be the ground strap - I haven't checked. The other just did its 72nd start since last charge. That is good enough for me.

    Oddsey 680

The other just did its 72nd start since last charge. That is good enough for me.[/QUOTE]. My 680 lasted 4 years. It says on the top of battery has to receive 14.2. Put a digital meter on buss bar And to ground. Put the meter between your legs and go flying. Mine was not putting out the 14.2. had to land and a just regulator 5 times. Puts out 14.6 and 6 years later it's like new. If you have wood or carbon blades shut down with mag kill only. If you have high compression it will wing thru the compression like it wasn't there. Good for 3 hours in the summer time.
