Charging of non rechargeable batteries

First of all statement:
I am aware of fire/explosion risk and i'm not recommending anyone to try to recharge non rechargeable batteries.

As some of you probably know, non rechargeable AA/AAA batteries can be recharged but it is not safe because chemicals inside can expand when get warm which may lead to explosion/fire.
Some guy on youtube charges them by setting power outlet to power on, power off every 15 minutes to avoid battery heating by using timer outlet.
That's how i want to charge my standard alkaline AAA's.
Only thing that bugs me is how many amps and volts should i use and for how long time?

For those who wanna tell me to just buy rechargeable batteries - i already have them - sanyo eneloops and maha c800s charger. But i wanna try this.

You already know to buy rechargeable batteries, so we'll leave it at that. No one here on the forums will advocate recharging non rechargeable batteries. Having to stand there and cycle the current on and off to prevent overheating, makes my time worth nothing. It isn't.
Maybe one of the members can figure it out mathematically to give you what you want. hang in there.

When I need a quick boost I'll charge them off a 12V deep cycle battery until they get warm.
