guyz i want to design a charger for 100AH lead acid battery for my U.P.S but i dont know what current the battery should be provided with please some one let me know the necessary information thanks
 
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.
 
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.
