Hi Kepler - We don't convert Land Camera batteries, but it's a modification you can do yourself pretty easily (google around for tutorials). Johannes is correct; we refurbish Polaroid SX-70, SX-70 Sonar, SLR 680, and 600 cameras. Come and visit the shop sometime!
They might help you but i think they only refurbish cameras. Give them a call!
