Odyssey tech manual has the recommended charging profile (Page 15):
http://www.odysseybattery.com/documents/US-ODY-TM-001_0411_000.pdf
Bulk to 14.7v,
Absorb at 14.7v until current flow drops below 0.001 of C10 amps (for example: 100ah (battery capacity or C) x 10 (C)10)) = 1000a x .001 = 1a)
Or, absorb at 14.7v for 6-8 hours
then drop to
Float at 13.6v
In other words, basically the same charge profile as any other lead-acid battery except it likes to get up to 14.7v on the bulk and keep it there during the absorb, instead of bulking up to 14.4v and dropping to 14.2v for absorb the way most chargers do (and most manufacturers recommend).
A 3-stage 14.4v/14.2v/13.6v charger will still get the job done - but it'll take longer (prolly an extra day or two of sitting at float voltage) to creep up those last couple of percentage points to reach 100% full.
that's helps. i thought that i might be over charging the batteries for some reason. i remember reading Optima suggesting the lead/ acid setting and was not sure why. I also noticed that Batteryminder made a specific charger for Odyssey. after reading your post i check the Odyssey owner manual and it reads "Low power 2.0 amp chargers for storage charge will keep a fully charged battery fully charged but cannot recharge if the ODYSSEY battery becomes discharged." why would that be? it also talks about returning 105-108% of charge and that most chargers only get 80%-90%. I'm guessing they make the assumption a 2amp charger will not have the brains to do that.
