Nate, A nearby hospital is required by law or regulation to replace on an annual or biannual basis the SLA batteries in many items of equipment, and the local radio clubs are the beneficiaries of this policy. Batteries in the 12 to 40 Ah range are found in portable X-ray, defibrillator, dialysis, heart-lung, and oxygen generation equipment, just to name a few. Check with the Operations Supervisor- the person in charge of keeping the hospital running- to see if such batteries are available for acquisition by local Hams.

Make friends with the right people, sign paperwork that the batteries won't end up being improperly disposed of (and a PR nightmare for the original owners) and haul away as many as you can carry in your vehicle without breaking the leaf springs. <snip> Nate WY0X
