For stringing up wires into trees to suspend various antennas. Built by a co-worker/machinist.
With 25 Amp fuse and Anderson PowerPole connector. Constantly being charged by a 4' x 1' solar panel and a Morningstar charge controller.
Bought for Y2K, and is charged maybe every 2 years using a regular car battery charger. Charging is not always successful, unless desulfator (see next picture) is used on it for a week - then the green float appears in the specific gravity float window of battery after charging for about 12 - 14 hours.
For restoring the 13-yr old deep-cycle marine battery - battery clamps not included with desulfator.
