[QUOTE="FuzzyGrub, post: 253951, member: 3438"] Thanks for posting. I haven't see those particular words before. But, when I compared it to battery voltage for fully charged and 75% charged battery, 5% is next to nothing. Fully charged is 12.7V, 5% discharge is 12.64V, and 10% is 12.58V, and 75% is 12.4V. The only time I'd be near the 5% is on the mid-winter charge. Ie a float charger would operate in this range. I don't use a float charger. I have seen some DC mfg recommend not using a float charger. After an hours use on a trolling motor, I'd bet your voltage is below the 5% mark, probably the 10%. Check it the next time out.
