German solar battery discharge to charge in time

Germany sunshine using the accumulator discharged after no timely charge, resulting in battery power loss phenomenon, next time again using the normal charge, so our engineers advice is Germany sunshine after the discharge battery should be charged immediately.
A battery with a discharge from the load to the low state must be recharged within 72 hours after discharge to avoid battery damage. UPS in idle, should disconnect the battery, otherwise it will lead to the damage of the battery discharge connection in a few days to a week, if after the discharge the battery for a long time without recharging, will lead to plate oxidation, i.e. lead sulfate crystals in the battery metal plates or curing on the charging method commonly used will be difficult or impossible to make the lead sulfate re decomposition, which leads to premature cell damage.
So after the end of the use of German solar battery, as far as possible for the first time to charge, so you can also extend the service life of the battery.
