Review on ⚡ TecMate OptiMATE 1 DUO TM-409: Advanced 12V Battery Charger and Maintainer - Fast, Safe, and Efficient Charging at 0.6A by Nick Mcvey

Excellent outdoor tender. The only thing that annoys me is that when I searched for a "weatherproof battery tender" I didn't find it, glad I found it! Consumes around 0.8kWh per month when charging (I connected it to Kill-a-Watt for a couple of days to find out), which works out at around 25 cents per month here. Brought my dead battery back to life. I used the Taymac MM510C Weatherproof Single Outlet Protective Cover for Outdoor Outlet 3-1/4 Deep Clear box to provide a weatherproof connection point for the plug (as pictured) also from Revain Looks and works well awesome, I'm definitely glad I chose this unit for the "Delco Battery Tender" that I've seen fire reports and photos from (yeahhh!).
