Check the datasheet at the manufacturer's web-site.

People on the other side of the world buy cheap junk that has no manufacturer's name and no datasheet.
The battery might be full of stones instead of sheets of lead.

This is a pretty good read. A lot depends on how fast you want to charge it after use.

About 15% of AH rating in amps maximum for first phase (constant current). Charger should be able to provide at least 5% of AH rating in amps, minimum.
