Will 50W ZeroStart Heater Pad Be Enough To Warm Up Small Tractor Battery In A Barn In Montana?

Question:

Would the 50-watt Zerostart be enough for my small tractor battery? I park in an unheated barn in Montana.

Dale, the 50-Watt Zerostart Heater Pad # ZE77FR is a great choice for small tractor or compact equipment batteries. It fits Group 22NF, 26, 26R, 51, 51R, and 70 sizes and keeps them roughly 60F warmer than the outside air. For Montana winters, plug it in overnight when temps drop into the teens and you’ll see much easier starts in the morning.

Do you have power at the barn, or will you be running it from an extension cord?

I’ve got an outlet near the barn door, so I can plug it in at night. Tractor’s a Kubota B2601 if that matters.

@Dale Oh nice, that's perfect! Just plug it in when temps dip below freezing and you’ll reduce the chances of that battery dropping voltage from the temperatures. Freezing weather absolutely kills batteries as I'm sure you know. If you’re running a block heater too, that little combo will make it start with ease.
