LEad Acid battery isn't intended for fast charging. Really it's as simple as that.

Allow 10 to 14 hours to charge it if you want a reasonable life from an expensive battery - 5 years or even more with care

I am confused here......

What is considered to be battery damage ?

Short term capacity or longer term lead flaking loss or  what ?

The manufacturer of the battery should have charge data available. With newer technology, this is referred to as the 'C rating' ('C' is often thought of as 'charge' but could also be 'Coulomb'. Although intended for larger capacity batteries, this website http://www.trojanbattery.com/tech-support/faq/charging.aspx has a key line that would be good to follow...

Example: A good charging rate for a battery with a 20-hr capacity of 225 amp-hr is about 22 to 29 amps. You can of course go slightly higher or lower depending on what is available on the market.

In short, about 10% or slightly more than the AH rating of this type of battery will work fine. In your case, just under 2A would probably be OK if you monitor the event. Most lead acid batteries are not designed for fast charge. LiPo batteries handle this method well...within reason.

You'd have to give it 20A to get the thing charged. If you try that with an SLA, it will die in less than 30 charge cycles.
