There seems to be conflicting information about batteries installation. I have tried several suggestions, but none have worked for me.
I first tried
ocamlfind batteries/ocaml
but that gave this error:
ocamlfind: Cannot find command: /username/godi/lib/ocaml/pkg-lib/batteries/ocaml
I then tried copying the ocamlinit file from the batteries directory to .ocamlinit in my home directory. This gave this error:
Cannot find file topfind.
File ".ocamlinit", line 38, characters 0-20:
Error: Unbound module Toploop
I am using ocaml 4.00.1.
Note: I apologize if this question is redundant with this one ocaml batteries compiling : Unbound module Toploop but the answer given was not explicit enough for me to actually try.

Like @rgrinberg said, try to install batteries with opam. For that, first download the quick installer:
$ wget http://www.ocamlpro.com/pub/opam_installer.sh
Then execute this script:
$ sh ./opam_installer.sh /usr/local/bin
It will install the latest "stable" opam (you can of course change the path /usr/local/bin) and the latest version of the OCaml compiler.
After that, you just need to run:
$ opam install batteries
and it should be ok.
You can also check ocaml.org install section (by package manager) or opam website.
