Review on 🔋 Optimized Battery Bug BB-SBM12 Monitor for Starting Batteries by Ryan Whatley

I have bought 3 (three) of these units and only one is still working properly. The other two give false positives for battery failure, sometimes dropping to 0% health when the battery is healthy. I know this because I replaced a known good monitor and it has been running at 70% or better for the past few weeks. I don't know if I will be returning these two units to Argus or not but I should note that in the past they replaced one for me due to a cracked screen occurring when my hood came down and hit it! Make sure you are careful when assembling this thing and always connect the wires directly to the battery terminals.
