Your battery will charge when the phone is turned off.

Try to connect your phone to the wallcharger without battery. Place the battery back. If the phone doesn't turn on again just let it recharge for a few hours.

I've tried this method. The phone did not turn on, no light, no logo. I disconnected it after about half an hour, but battery is still dead. How long should I charge it and what percentage of capacity can I obtain? Could you please describe me in a few words what is happening when this method is used.

I wonder if voltage can be different from nominal 3.7 V (for BL-5J). And how connect my battery with the other charger (or phone).
If "the other phone" takes BL-5J then there is nothing to speculate. The contacts are already set up for you. The universal one I posted a link to can figure it out by itself, even if you reverse the battery. There are other ways but if you have to ask, then you better stick to tried and foolproof ways like those already mentioned. DIY can be dangerous in the hands of an amateur.

Your best bet though is to invest in a universal one, like e.g. this one (in your country variant, obviously). It costs peanuts and can be used for anything: cameras, other phones... Ever since I got mine I am not taking anything else on holidays.
It is what I would suggest.
I have a few different types of chargers.
My uboc has replaced them all.

a half hour might not cut it.
If your battery still doesn't want to comply...
perhaps it is the fact the external charger is faulty....
possibly..
but I'd guess..
I'd say you got a very dead battery on your hands.

I have external charger for my DSLR Nikon. It has output voltage 7.4V and current 0.9 A. Can I use it to charge BL-5J battery (3.7V) ?

So this method of charging is useless, because nothing is charged.
