battery can hold a charge.
Battery Desulphation - break down the sulfates; optimize the charging.
Soft Start - minimize the startup currents; avoid the sudden voltage surges.
Battery Initialization - start charging with a gentle (soft) charge.
Battery Bulk Charge - begin the bulk charging to 80% of the battery’s
Absorption Mode - deliver small amounts of current when the charge level is
Battery Recondition - check battery status, recover with a small current.
Battery Optimization - finalize charging, and bring the battery to maximum
Battery Float Charge - maintain the battery fully charged, without
Battery Restart Charge - restart charging, when battery capacity is <85%.
Switching between modes is fully automatic and hands-free.
This 10-step charging process ensures that each battery gets the power it
needs, and can be left 24/7 without overcharging or damage.
