Most motor movers isolate themselves after a few minutes of inactivity so shouldn't have flattened the battery.

Recharge the battery, ideally with a smart charger.

I leave mine on for weeks and the battery is fine.

That’s a good quality smart charger. Don’t write the battery off too quickly. See what time on the NOCO achieves. You could also check the battery connections. Not just the clamping terminal to the battery but the security of the cable wires within the clamp.

I'll second that - 5 years with the battery connected to an onboard supply giving 13.8v float voltage will have allowed substantial sulphation - a good smart charger will go through a reconditioning cycle and help restore it.

Will check all those,thank you,I tried to move caravan with motor mover last week,with no luck,because unbeknown to me brake was stuck,kept trying and trying for to long tbh,I wonder if that drained the battery ?

In that case check the fuse for the motor mover, they are somewhere in the rating of 80 amps, so if the brake was stuck on, the fuse might have blown.
