can i get an opinion? after 24 hrs of sitting 80 degree day i read a maximum of 12.80-12.85 dc volts across the battery. i started using the battery tender 2 weeks ago-- harley will fire right up, perfect state of tune. earlier,, without using the batt tender i felt a sluggish starter,, seemingly weak initial starting,, so i hooked up batt tender an the response was a 100% improvement in starter turning motor over an it fires immediatley. bear in mind this is agm harley battery 2 yrs old but compression is 10.5 -1. i'm wondering if 12.80 dcv is a bit on the low side--any comments? was around 12.70 -12.75 several mornings without batt tender + hooked up. also checked charging --perfect 14.75 under running conditons. im opinin here but i really think an odessey battery-- extra heavy load may be in order for this higher compression motor an the oem harley battery just hasnt got the umph needed to get a good strong spin on the engine. anyways mull it over an lemme know what yall think--electrical isnt my best area of hd mechanics..................
