EFB (enhanced flooded battery) I left the lights on for more than a week because of Coronavirus

I have a Renault captur 2016 vehicle with start and stop capability, the battery is EFB 70Ah 720A, I couldn’t start the engine with cables connected to another standard battery of another running vehicle, the battery is almost 3 years old, so I took it out and now I’m charging it at home I’m wondering if it’s even possible to revive this battery?

I never had any problem with this battery before it was never totally depleted like this.

I’m using truecharge 20 charger microprocessor controlled by Xantrex and hopefully it would help and stop, I’m afraid it will get overcharged.

Any advice would be helpful…
