I have a four year old battery for the back-up sump pump. Instructions
say to change it every three years (yeah I noticed I was behind),
however, the lights on the pump itself indicate that the battery is
still in good shape. So, should I trust the lights or just replace the
battery?

I just paid $80 at Sears for a replacement Marine Deep Cycle battery for my
backup sump pump. Amortized over 4 years, that's $20 per year. I think you
can afford to replace your battery even if it isn't needed, at $20 per year.
Small price to pay for lower risk of basement water damage.

You get insurance even if you don't need/use it.
