Selection designed to choose the most suited charging current based on the type and size of the battery
(lead-acid or lithium).
Charging current
Battery capacity
*Lead-acid battery equivalent : Lithium batteries have better starting performance (CCA) than lead-acid batteries. This is why some
lithium battery manufacturers indicate the lead battery equivalent (EqPb) corresponding to the capacity of a lead-acid battery with
the same starting performance. For instance, a 10Ah LFP battery will have approximately the same starting performance as a 30 Ah
lead-acid battery.
• Lead-acid charge curve:
The Gysflash 8.12 PL uses an advanced 7-step lead-acid charging curve that ensures optimal performance of your lead-acid battery.
