Hi Minnik,

I didn't have to look for it so long to find it but it's probably not
the right one, but here it is.

For charging a 12 volt battery, a 300 ohm 1 watt resistor should
be inserted in the collector of Q2, R3 should be increased to 400
ohms and the secondary voltage of T1 should be doubled.

What batteries you are speaking about?

NIMH
NICD
SLA
Li ION

For different batteries you need different chargers.

You looked for a month and it is a homework problem? Isn't it _way_ past due? Why won't you work it out yourself anyhow?
