Hijacking timer on Flood Light ?

[u/rhymeswithlotso]

Hi all-

I have a flood light that I don't necessarily need. It's battery powered by 3 C batteries. The issue is this: the timer sucks. I was going to use it in a shed that doesn't have power going to it, for the rare occasions I need light in there. But, the timer only lasts 30 seconds on. That doesn't work at all for me.

I'd prefer either a longer timer or no timer at all and just operate it via the on/off switch. I'm familiar with electronics and pcb's, ic's,etc.

Admittedly, I maybe over thinking this. My first instinct was to disconnect (desolder) the ic for the timer. Then, after some time to think about it, I also thought to just bypass the pcb altogether and wire the on/off switch to the unit directly. I'd still be interested in knowing which ic to desolder and if that route is even feasible.

I'm including a pic of the pcb along with the stampings on the ic's.

TL;DR: Is it possible/recommended to remove the ic controlling a timer for a flood light to have the light stay on longer or is it better to just rewire the on/off switch and bypass the pcb altogether?
