ProMax 12V Car & Truck Battery Jump Starter with Overload Protection - Emergency Vehicle Starter for Dead Battery, Roadside Assistance & Power Outages

Battery had died in my 2003 Toyota Land Cruiser. I bought a new battery at Walmart, but within about 4 days after I put the new battery in it died. I charged it up, but it was dead again within another 3 days. I started researching why, and a parasitic drain was likely the cause. That lead me to a comment in a news group for land cruisers to this Priority Start product. Putting this on would prevent the battery from draining below 11.7 volts. So I returned my now dead battery and got a replacement new one. I put that in along with the Priority Start (photos attached) and I have not had any issues since... We have driven the Land Cruiser at least every 3 days, so for now, the Priority Start has not had to engage. I know since we have not lost our Trip A and Trip B values from the Odometer, and Radio Settings have not reset. I will know for sure in a few weeks after it sits for a week without being started. Only real drawback will be losing the Trip A/B and Radio Presets. Trip bring the primary issue since our Fuel Guage is unreliable and I just reset Trip B for every fillup and I know when I get to about 270 miles on the Trip B meter, its time to fill up. I now will note the mileage from the odometer and do the math just in case the battery does die. So far, good product, will know for sure by the end of February if it kicks in and cuts off the Battery and allows a good restart.
