Johnson's Telemetry! how to get battery changed???

aloha my bradahhs, i have a few of the Johnson collars that the batteries need to be changed.. im trying to get in contact with them but they are currently closed due to bad weather.. but i was wondering if anyone has any experience sending collars to these guys to change the battery?
Mahalo

I had 6 that I sent in back in 2006 still going strong. had to wait a few weeks to get them back. I think was like 50 a piece to change the battery plus shipping.just get in touch with them and go from there.

mahalo nui brah!
thanks for the ball park i was debating if i was going to buy new collars but 50 not bad. do you have any problems with these collars? im not sure wat they are capable of the guy i bought um from said they was gud but im on a 9 at 20yds. i noticed they arnt as popular as the intelo and wat not.
