Replacing cells in AB Proformer battery packs

DisputedParticipants disagreed and reached no conclusion. Read the findings as positions, not as an answer.
What the thread found
- Proformer battery packs contain Sanyo N-1900SCR cells configured for 14.4V and 1900mAh capacity according to pack labeling
- The 30 watt-hour specification suggests the manufacturer rates the pack capacity higher than the individual cell rating
- Generic import replacement cells rated at 2400mAh are available as an alternative to original Sanyo cells
- Recelling Proformer packs with original Sanyo cells becomes financially uneconomical compared to purchasing new batteries
- Generic import cells have shown performance comparable to original cells when used by service technicians over multiple years, though some users report capacity and durability concerns with generic cells
- The Proformer is described as a simple NiCd battery system that is straightforward to recell
Depends on
- Generic import cell performance claims are based on limited experience from one service provider over two years
- Users reported prior negative experiences with generic import cells regarding capacity ratings and amperage handling
- Cost analysis was specific to the timeframe of the discussion and may not reflect current pricing
- Only one confirmed cell model identified; possibility that manufacturer changed cell suppliers in recent production runs
