Charge Battery With PC Power Supply

[ksnl2008]

Hello everyone,
I have an old PC Power Supply. Is there any idea to charge 12V 110Amp Led-Acid Battery with this Power supply?

I shell be very thankful to you for that

Not without major reconstruction.
To charge 12V/110Ah battery you need 14V(and a little bit more) and at least 10A.

Apart from needing 14 - 14.5 V output, the SMPS must also be able to deliver constant current, it must have a current limiter rather than a overcurrent shutdown. Some SMPS can, some can't. A PC powersupply probably hasn't a usable constant current mode. The SMPS must also allow increasing the output voltage, e. g. by an adjustment potentiometer. A lot of industrial single voltage SMPS can be used as a battery charger, but it must be checked with datasheet first, if it's possible at all and also if this operation is allowed permanently by design, and then verified empirically.
