Mighty Max Battery ML8-12 - 12V 8AH Replacement for GT12080-HG FiOS Systems Battery

Has anyone installed and used this battery for at least three years?

This battery only lasted 9 months. I'm ordering a new one to stop the beeping. How do I make a claim under the one year warranty?

On my solar charge controller it asked me for battery type it's a numerical number

Hello has anyone ever used these with an inverter to plug in lights in general. thinking of buying this for an event where plugs are limited.Thnk U
