Don't do it! Complete discharge of the battery will over heat the battery and cause serious problems. If the plates warp (very likely) they can short and kill the battery. Study the information on the Trojan battery website rather than following second hand information that is likely adrift.
Lead acid batteries use paste because it is porous. This means they already are designed for best conditions right from the factory, and need no conditioning, other than being topped off. The only truth in this might be when we look at the power curve during the batteries life that shows a slight increase in available power after a few cycles( not complete discharges). The important thing to remember is there is no real shortening of life by using these cycles, only if you insist on discharging below, in my book, 40% charge, I like running to 50% charge on my investment. I then will start the genset if I must go further.
Any Web site that gives you this kind information would get banned so as not to return there.
Likely I would not even buy from them to keep others from getting the business in the future.
Just my opinion.

This certainly doesn't sound true. If it increased the capacity 15% to 30% wouldn't the manufacturers do it so they could advertise a more powerful battery?
Instead they say specifically to avoid complete discharge as much as possible.

Hi all !
According to Ample Power, breaking a battery in properly will not only
permit faster charging and discharging, but it will also provide a 15 to
30% gain in Amp-hour capacity.

The logic behind this is:
When a battery is new, the plates are smooth from the active material
being pressed into the grids. During discharge, the smooth plate
surfaces increase in area due to etching of the active material. In
effect, valleys and mountains are carved into the plates. With this
increase in surface area, higher currents can be conducted, and an
increase in capacity results. As a result, the battery will accept
higher charge rates, and also support rapid discharges better.
It's the first time I hear about this. Is this another myth?
I'm also a bit concerned about the breaking procedure (1 to 5 complete
discharges, where the battery voltage falls to 10.5 Volts). It's
commonly known that we should avoid discharging a lead-acid battery
below 50%. Their "good initial workout" looks like a "beat to death and
repeat" to me...
Are you breaking in your new batteries this way?
