Unitrode makes two IC's designed specifically for charging lead-acid
batteries: the UC3904 and the UC3906.

The data sheets for these are available at:

http://www.unitrode.com/sect-6/uc3906.pdf

and

http://www.unitrode.com/sect-6/uc3909.pdf

They've got a few apnotes on these as well, unfortunately they're
not on line.

If you just want to scope Unitrode then check out:
