Affordable replacements are all good and important to have, with a caveat. Lithium-ion batteries at the $25 pricepoint come from a single well known place of manufacturing and are usually of the unknown quality. They may or may not be safe to use, and there have been precendents of self-ignition and self-explosion to the point that some airlines have banned or have attempted to ban the Li-ion batteries in the carry-on. A branded $99 battery (all brands) is not 100% immune to the same problems but occurences are much more rare, and typically each such failed specimen is taken back to the manufacturer for an investigation. The only forensic process in existence for failed $25 batteries is called «throw it into the dumpster». That said, a better QA process by the phone manufacturer does make the $99 battery reasonable. If all suppliers of $25 batteries could guarantee the same rigid QA process for the $25 batteries they supply, that would make the $99 batteries unreasonable.
