For a liquid lead battery, this is quite normal. Current will drop very slow in the cv phase, as it is "bubbling out". 2,45V per cell is really quite high. Normally charge voltage should be dropped after reaching 2,45V. iCharge will not do this as far as I know.
You should not charge a solid/gel lead battery with the iCharger, as it will not tolerate 2,45V per cell.
I don't use iCharger to charge lead battery, I just connect it to my 13,8V power supply. This will give much longer life for the lead battery.
But it would be a good idea to talk about perfecting lead battery charging program in iCharger. But only after LiXX is perfect, LiXX ist what is important. Most if not all chargers do a very bad job when charging lead batteries.
