I have seen discharge rates as high as 40%/month in new wet cell batteries.
Please tell us what brand of battery that was so we can stay away from them.
In 40+ years of dealing with wet cell batteries, that is the first and only claim I have ever seen of a self discharge rate anywhere near that bad in a "new" battery.
You are right that there is an inherent rate when new due to the chemistry and construction......which is pretty much constant over the useful life of the battery. It is the chemistry CHANGE mostly due to sulfation that makes the self discharge rate become worse over time.
Add to that high temperatures. The higher the temperature the faster the self discharge rate even with a "new" or "healthy" battery. It has far less to do with the manufacturer although there are several that are inferior.
