On a "smart" system, it wouldn't be delivering .2a constantly. Once a certain voltage is reached, it would switch from "charge" current to a "maintain" current, which should be much lower. 200mA would be a slow charge but too high for "maintenance"....batteries don't lose power that fast on their own.

i put a cheapo HF 'smart' charger on them and it seems to be delivering in the 13.2 - 13.3V range. does that seem too high. also yea the amperage seems high at 3.5 - 4amps.
13.2-13.3 is ok.
Is the amperage your stating what the charger is rated at or did you get an actual reading on true amperage somehow?
The ratings are usually the max it's capable of, but battery condition should dictate what the puts out in amps.
If you had a charger with an ammeter and put it on a "low" (not dead) battery, it might show 3-4 amps for a few minutes but should rapidly come down as battery voltage goes up.
my personal experience with deep cycle batteries, is that if you don't use a "deep cycle" charger they won't take there full charge. perhaps every 6 months give them a "deep cycle " charge. Then leave the maintainer on them the rest of the time. I have always been able to get them back out from going bad by using a "deep cycle" charger..

yea i put an amp meter in line between the positive terminal and the positive end of the charger. i'll have to double check it again soon.
is a smart charger different from a deep cycle charger? this one is supposed to be able to do deep cycle.
Did I miss something in a previous post by not reading all of them?
Were we talking about deep cycle batteries? If so I would think completely discharged they might take a lot of current for a lengthy time? don't hae much actual experience with those tho...
