SNES carts with save files use SRAM, or Static Random Access Memory. Basically, it lets you save data to it for long periods of time with only a minimal charge to keep it active. As long as you don't save to it often, SRAM can last a long time as it uses relatively little power (as evidenced by the fact that most cartridges just use a watch battery to keep the SRAM alive). If you do save often, however, SRAM starts to wear out due to its volatile nature and requires more power to keep the data alive. Simply replacing the battery won't help much there; you'd do better to replace the SRAM itself, if you can.
