if the battery is badly discharged it could charge that much at first, as the cells become more charged the charge rate should drop down.
of course if the battery has some kind of problem in the cells it may not drop down. what is the amp rate during charge?
it will start high and drop down as the cells become charged.
the max amp rate is 300 so you could see the amp rate go above 200 easily with a discharged battery. the voltage rate will always go higher than the voltage rating of the battery, its the amps you want to watch.

while charging remove the cell caps and see if there is any unusual bubbling, there will be some but if there is alot and if you see any smoke that is an indicator that the cell might be bad.
also if you smell rotten egg smell while charging that is also an indicator there is a problem in one or more cells.
