A hundred cycles is a substantial percentage of a flooded L/A battery's life. For critical applications we used to "burn in" new batteries. 14.8 volts constant until the cell started to bubble at more than one bubble per second. This rendered more than 95% CCA and reserve capability.
Please keep in mind, the power company usually feeds even a small battery manufacturer with 750 kw capability. Electricity is expensive. So manufacturers green and condition new batteries with as few kWh as possible.
"Cycling" a new battery is a better PR term than "For best results slow charge the battery several hours". Plaid suits, fluorescent ties, and Italian loafers write the hype.
