You can either use the trickle charge or fast charge capability with the Robop supplied charger. Using the normal or “trickle” charge requires approximately 8 hours to charge, so it is best left to charge overnight. The charger’s fast charge facility delivers up to 2.5A and when the battery is fully charged it switches automatically into trickle charge mode. This is indicated by the red LED turning to green. Is other battery technology available?
