Rollei SLX / Rolleiflex 6000-series Battery Repair

📷 Vintage camera, modern battery fix

A customer brought us a used Rollei SLX / Rolleiflex 6000-series battery that looked fine — green light on the charger — but the camera wouldn’t power up at all.

These original batteries are no longer manufactured, and there’s no reliable resale source either… so we took the job on.

🔋 Rebuilt with 8S industrial Ni-Cd cells
• 1.2 V per cell
600 mAh vs original 500 mAh (+16% capacity)
• Brand-new, matched cells, spot welded not soldered.

Bench-tested and verified on a capacity tester:
➡️ 639 mAh delivered, discharged to 8.9 V pack voltage

😊 Customer went away very happy
