Had my factory battery (30 mos. old) replaced with a new AGM on warranty several weeks ago. Ordered this Desulfator from BatteryMINDer® Model OBD-12: 12V On-Board Desulfator (batteryminders.com) and it is scheduled to arrive tomorrow. Looking forward to setting it up and working to get more life out the new one.

Ironically, during the same week had my Galaxy battery also replaced on warranty. I've committed to make an effort now to try and extend the battery life on all my devices.

Found this video explains the BMS system. It shows how you should jump start and charge it too. So many have never had this system (myself included) and there's always questions about what to do with these. Overall a good helpful video but the guy does get a little repetitive towards the end.

Yes, this probably qualifies for the longest thread title on here. ?

I got done with the whole bms crap, and disconnected the the bms at the neg. terminal.
No More ASS. anymore and the battery receives a steady 13.8 to 14volts kust like before Fords better idea!

How is the battery minder working out for you ? I bought a competing less expensive product from pulsetech hooked it up to my 4 yr old battery but don't expect much from it mostly bought it for my Weize AGM bargain batt waiting for the oem to fail, then I expect it to yield results.

I watched maybe 4 minutes of that dude's video and it served to completely reinforce my decision some yrs back to disco the bms and committed to never again watch any of his pathetic videos.

dtech,
I am very challenged when it comes to electrical systems. Tony @TJC is guiding me with steps on how to learn to use this system. I'm not sure yet how to monitor the BatteryMINDer results but here are the readings so far according to my battery tester and hope they help. I have a NOCO charger that I haven't used yet but need to start hooking it up when the battery shows that it needs a charge after testing.

Kee in mind batteries are chemical devices and readings are impacted by a number of factors , especially by temperature differences and if you still have the bms operational I'd expect to see a wide range of readings.

Yep, temps matter. I would try unplugging the BMS module at the neg terminal as an experiment. Drive it for a month of two and then check your results. You might be surprised.
