Solar lights stay on in sun

[dillondays42]

I have a 3 light two planter solor post. The solor lights would not go on after a year. I replaced the 2500 mah rechargeable batteries with 2300 mah batteries. The lights come on, but stay on in the sun. I put the old batteries in , and the light did not go on. I now have it in a "recharge" mode in the lamp. I bought the batteries and they said they were already charged. Anyone have an idea why the lights stay on?

Thanks

They should be off in the sun, and turn on when it's dark. I covered it in the garage, and they didn't come on.
