Horrible fright, err, harbor freight. I've lived off of them with some silicone around the seems.

Bought one at the hammer store and it lasted about 6 months

Check websites that sell automatic gate openers. Topens is a well-known name, that's what I used when I built my rolling gate across the driveway down near the road. Couple hundred feet away from any power source, but lots of sunshine. Opener requires 24v, so I got two 12v 25 ah batteries (same as powersports/atv) and a couple of solar panels on the stone columns that support the gate. The battery tender takes the power from those and keeps the two batteries charged just fine.

Note of caution: Do NOT use lithium batteries with most of the available solar battery tenders on the market. The charging characteristics of lithium batteries are nor compatible with lead-acid or nicad battery chargers.
