Even though Battlarts' style was based on shoot wrestling, the promotion often cooperated with other shoot style and mixed martial arts promotions, including Fighting Network RINGS, Kingdom, Michinoku Pro and Big Japan Pro Wrestling, therefore matches sometimes resembled more traditional pro wrestling matches.

The biggest co-promotion occurred on October 17, 1999, when Battlarts and The Great Sasuke's Michinoku Pro Wrestling presented "Michinoku Pro vs. Battlarts", which was headlined by a tag match pitting the owners of both promotions (Great Sasuke and Ishikawa) against Jinsei Shinzaki and Alexander Otsuka.

The promotion ceased running regular shows and events in 2001 due to "management aggravation".

Battlarts eventually began to run monthly shows mainly in Tokyo, Saitama, and Shizuoka Prefecture, often co-promoting with Daisuke Ikeda's Fu-ten, Kiyoshi Tamura's U-STYLE and Satoru Sayama's Real Japan Pro Wrestling promotions.

On September 14, 2008, at a press conference with Yuki Ishikawa and Shinjiro Otani Battlarts announced a working agreement with Pro Wrestling ZERO1.
