Deep Cycle Battery on Gate Controller

I have a 12 volt battery on our driveway gate opener. The battery is being charged by a solar charger that goes into the gate controller box. The gate quit working recently so out there I go. There is 14.4 volts going towards the battery until it gets to the inline fuse. After that, there is 11.6 volts. I was thinking bad fuse holder or fuse, but when I disconnect the charge wire from the battery, it jumps back up to 14.4 volts.

Bad battery?

A loaded circuit is the best way to locate a voltage drop and you found one. Not saying your battery good though. You will have to make that determination after you have charged it up.

If you borrow a tool more than twice, you need to own it You get what you pay for!

It's close to 6 or 7 years old. Exposed to the elements the whole time even though it is enclosed in a battery box.
