Turning an ordinary 12-volt car battery charger in to a regulated charger?

Turning an ordinary 12-volt car battery charger in to a regulated
charger?

Hi,
I was just wondering if any electronics whiz kid out there could tell
me if this is possible, or if indeed this is what I require.

I have a 6amp 12-volt battery charger for charging my car battery, no
problems here!
However I also have a motorcycle that has one of those sealed
batterys, now from what I have read I believe that you are not
supposed to charge this type of battery with a normal charger, as it
will damage the battery somehow.
Is this correct?

Would it be possible to build a small circuit that I could put in line
if I wanted to use this charger to charge the motorcycle battery
without causing any damage to it? or am I barking up the wrong tree?

Thanks for any help.

There are different types of sealed battery. Check with the manufacturer of
the battery as it's probably ok.

Most lead acid batteries use a standard constant voltage charge profile but
the recommended float voltage can sometimes vary slightly from make to make.

I have looked at the battery & there are charging instructions on it.
It states:
Standard charging 0.9A for 5 to 10 hours.
Fast charging 4.0A for 1 hour

Fast charging is only recommended in Emergency conditions.

Do I need to get a different charger for this battery, or could I add
some circuitry to my charger to drop the output of it?

Thanks.
