Optimate LFP 4s 5A - Battery Conditioner

Mornings all - Optimate LFP 4s 5A Battery Conditioner came with the car (Exige 2016 Club Racer) - nicely wired in. On connecting lots of lamps flash on boot-up then just sits with the on Green LED - the Maintenance LED remains extinguished - is this correct? You Tube etc not providing me with the answers I need!! Many thanks
