For charging I see a spec of 10-13 percent of the 20ah rating.
I'm manually discharging in the garage and curious if flooded wet cells prefer a strong discharge? Or is something like 5 percent sufficient?
Charging at 10% is recommended for longest battery life, but the typical deep cycle (eg 6v golf car or a T-1275) can take 30%. The higher rates are necessary for short gen times doing 50-80s while camping.
Discharge rates similar for battery life. 25% discharge is about max for the internal chemistry to keep up.
A long slow discharge leaves the battery undercharged that whole time, so you would want to recharge it to full real soon and maybe even do an overcharge on it.
You do what the job requires and get new batteries as needed for that. Can't let the battery decide whether you can do the job!
