well, his normal turrets have an attack speed of 1.75, means they give a charge boost of 8,75% per second. Cooldown is 12s, so regular recharge per second is 8.33%. So if his turrets attack continuously, they recharge 17,08% per second, so the laser cooldown is 5,85s.

His ult turrets have a lower attack speed of 1.0, means they recharge 10% per second (recharges twice as fast). Regular recharge is 15% per second, so the ult turret recharges 25% per second when firing continously, making the laser cooldown 4s.
