Charging or battery problem?
This is a diagnosis question, I guess, and so I hope it fits your thread.
I have a 60 ahr lead acid deep cycle battery relocated into the trunk of my 1998 Civic. The battery is failing. That's the second time in a year.
My main suspect is an over-draining incident in Nov/Dec when the car was offline and the battery drained down to about 60%. It had been awesome before, but afterward it started to show difficulty almost immediately after.
But I want to be thorough before throwing more money at another battery. How would I test for (1) parasitic losses, (2) poor charging voltage from my alternator, (3) poor charging from my three-stage onboard grid charger, and (4) too-high resistance from cables used to relocate the battery to the trunk.
Thanks for this great thread idea.
