Dyna Battery
My 2012 Superglide Custom's battery decided to die just as I was going to try to get a last ride in! The bike is now tucked away in the garage so I'm not going to replace the battery until next spring since it won't be needed until then. What did you guys replace your battery with? I want something with at least 310 cca. What do you recommend? Final question. I took the battery to Auto Zone and they tested it and said it was ok. The lights and everything light up when I turn on the key, but the starter just clicks when I hit the start button. Also, the battery shows fully charged on the tender. Curious about that.

Load testing is crucial in testing automotive batteries.
It's a good idea to have a load tester for testing all your vehicle batteries.
Your battery may show 13 volts but it can be a flash charge.

If it's the original battery, it's 9 years old. It doesn't owe you anything at this point. Stock HD batteries are underpowered IMO. A 10 horse lawn tractor has more CCAs. I went with the YUASA above. Was thinking of going with a scary flammable lithium ion battery for more power but didn't bother because 1, Scary flammable, 2, need a special charger, and 3, they lose their chi if drained too low/aren't good for cold weather. Would like to hear if anyone is running one of these and likes it.

I guess my main concern is the fact that it tests that's fully charged. My head lights and dash lights are nice and bright, but when I hit the start button the battery sounds dead. Just wondering if that was normal for a bad battery.
