Friend called today. Working on his 2010 Dyna. Had battery out for checking/cleaning leads etc. Normal maintenance. Not sure how it happened, found battery laying on its side since yesterday. Normally batteries are supposed to remain upright. Only a few months old HD battery. Concerned if this had any effects on battery. Nothing is leaking. Voltage at 12.6. I don't think it hurt anything ?? On a battery tender now. Anyone have another opinion/wisdom. Appreciate any advice.
