Transcript – Battery Charging Cooler for Extreme Temperatures

I’m James McMurdo with IBEW Local 322. Have you ever had problems charging your batteries in extreme cold or extreme heat? I’m had that problem and this is my solution!

Take a regular, off0the-shelf cooler, pull the drain plug and put a charger strip inside of it and then ran our chargers in there. We also installed a light bulb, putting enough heat in the cooler that is needed to charge a battery in the winter. In the summer, you don’t need the bulb so you can just unplug that. You can keep the lid open, or close it, and it will maintain the optimal temperature for keeping your batteries charged and ready to go.
