How often do I need to desulfate my 12 volt battery...

It appears to affect 100% of the Hybrids, and some small number of EcoBoosts. I'll bet that every other battery issue that you've been looking at have been on vehicles with alternators, so you're not comparing apples to apples. I'd also bet that the only people NOT having the issue all drive long distances, so the 1/2A charging current eventually gets the battery up to 80% charge and they last a bit longer.

im a ford tech. The vast majority of Maverick hybrids do not have this issue. Also, the very similar hybrid system has been used since the 2013 fusion and MKZ hybrids. The same system is used in the escape hybrid. The design is the same. The charging rate is the same. Yet Ford has only seen this problem in significant numbers in the Maverick. The charging rate is the same as with other hybrids. . But some electrical and electronic components are different. It’s a DRAIN. And although it’s in significant enough numbers to be a problem, it’s nowhere near the majority of owners . If it was, we would be overwhelmed with this issue because most people drive less than 20 miles daily. Most customers will NEVER agree to regularly charge their battery. And most would NOT tolerate yearly battery replacements. The key to getting to the ROOT of the problem is finding the source module that's waking up the system. If simply changing the charging rate was the solution, Ford would have done that Ages ago. They aren't THAT stupid. I hate to see argumentative. But I work on these vehicles. And our dealership has only seen FOUR with this issue. Even though we're a small dealership. We have a customer with a fleet of hybrid Mavericks driven under the same conditions They have this issue with ONE of them. ONE. that's nowhere near 100%.
