Question:
Im looking at the MouseBlocker Prox for my 2017 Ram 2500 which will be garage kept thru the winter. The truck will only be started about once a month so battery charge is an issue. If I want to use supplemental batterys left outside the vehicle to power the unit what type/size/capacity battery would you recommend that would last for 30 days or so before recharging ? I would locate the unit in the engine bay. Do I need another for the cab to be on the safe side ?

Hey John!
The MouseBlocker PROx # MB94FR can definitely work for the setup you're describing, but I think there's a better solution.
The one I'd recommend is the MouseBlocker PROx # MB34FR. It's essentially the same as the # MB94FR, but iInstead of connecting directly to and draining your battery, this one can be plugged into a 110V outlet in the garage to give you consistent rodent deterrence. I think that's better for intermittent use and won't require any additional pieces, except maybe an extension cord.
If you do want to stick with your original option, the # MB94FR is rated to consume 0.6 watts, which is 0.05 amps at 12V. Technically speaking, a 50Ah battery could handle that load, but it would likely have to be in the best conditions and being that you're from the northern part of the country, I wouldn't call that reliable. I did some research into it and if we estimate a discharge rate of 50%, you'd want to go with a Deep-Cycle AGM battery rated for at least 75Ah, and bigger is better in this case so a 100Ah or more would be even better. One will suffice for protecting your engine bay, but you'd want another for protecting your cab.
Is your Ram just a work truck that doesn't get used very often or are you just planning on facing a harsh winter? Does your garage have a history of rodent issues?

Thanks for your response Jerry. Much appreciated, especially the math ! This is the first year I'm storing the truck like this and the garage is a rental unit so not sure what to expect. No electric service there so I have no choice but to use the battery option. Thanks again.
