You have hit upon another cool feature of Odyssey batteries. Your 10 amp charger would shorten the life of a regular flooded lead acid car cranking battery because it is higher than the 0.1C charge rate. Most car batteries are around 65 amp/hr, and that is why you see most automotive chargers with an output of 6 amps. The (4) battery bank in my hot rod scooter I charge at 2.0C, that is 20 times faster. I use a 30 amp 48 volt golf cart charger and it is ready to ride in 25 minutes.

Over time, you will be very happy with your purchase. Just remember two things, one, ANY lead acid battery left in a discharged state for any length of time will have a shortened life and the 2nd probably doesn't apply to you, since you aren't using a modern automotive electrical system, and that is phantom loads. A lot of modern cars use up to 0.02 amps keeping brains alive. On a typical 65 a/hr battery, that small drain won't be an issue for 3 months of non use (engine running, charging system doing its thing). With just 16 a/hr, you could have starting problems in 3 weeks. A Model A with a 383 sbc stroker will have zero phantom loads, so no problem.
