After living in a place for more than 1 yr, painting is usually the L's responsibility.
If the batteries were for the smoke detector, its on you (your resp. to keep working batteries ALLTHETIME!!!)
As far as other damages, refer to Ohio's landlord tenant laws (http://orc.avv.com/title-53/sec-5321/whole.htm),HERE IS A QUOTE TAKEN FROM OHIOS LT LAWS
: "Upon termination of the rental agreement any property or money held by
the landlord as a security deposit may be applied to the payment of past
due rent and to the payment of the amount of damages that the landlord
has suffered by reason of the tenant's noncompliance with section
5321.05 of the Revised Code or the rental agreement. Any deduction from
the security deposit shall be itemized and identified by the landlord in
a written notice delivered to the tenant together with the amount due,
within THIRTY DAYS after termination of the rental agreement and
delivery of possession. The tenant shall provide the landlord in writing
with a forwarding address or new address to which the written notice and
amount due from the landlord may be sent. If the tenant fails to provide
the landlord with the forwarding or new address as required, the tenant
shall not be entitled to damages or attorneys fees under division (C) of
this section. "
DIVISION C GOES ON TO SAY:
"(C) If the landlord fails to comply with division (B) of this section,
the tenant may recover the property and money due him , together with
damages in an amount equal to the amount wrongfully withheld, and
reasonable attorneys fees."

I WOULD DISREGARD YOUR L'S LETTERS, BY SIMPLY SENDING HIM A LETTER (KEEP COPIES- ALWAYS KEEP COPIES) SAYING YOU DON'T OWE HIM A PENNY, THAT INFACT HE IGNORED OHIO'S LT LAWS, AND IN FACT, HE OWES YOU MONEY _____. GIVE HIM A SHORT PERIOD OF TIME (REFER TO LAWS OR ATTY) AND THEN TELL HIM YOU WILL TAKE HIM TO COURT . IF YOU GET NO RESPONSE... SUE!!
