Some have Die Hard and Interstate batteries installed, replacing the Ford OEM batteries. Most of those who have done this are reporting little or no problems. I am wondering if Johnson Controls have different specs for the Ford batteries as opposed to Die Hard and Interstate batteries?
Having drove a 2015 Prius for 7 years, hybrids will "click", "buzz" and "humm" up to 20 minutes after you park. You are not doing anything wrong, nor, is there anything wrong with your truck. This is what hybrids do. Hopefully this helps.
It is the same specs as my Die Hard. You should be good to go. But the end result will be the AGM battery. For now, you shouldn't have any issues for quite some time.
In my case dealer claimed that Ford will not supply original Maverick battery replacement. This is some sort of a new special design Mexican battery that is nothing, but trouble.
Yes, I thought of this too as my battery died after just 13 mos. Seems like a bad design. There’s a huge bank of batteries that drive the truck at low speeds. Why didn’t they connect it to the interior car battery as a fail safe?? Engineers?
Disabling all of these options when it's not being driven for an extended period might help, but it also means you won't be able to locate it if it's stolen. The main point of this message is to let you know that the battery is in saver mode, probably because you're not driving the vehicle long enough during normal trips. Like many devices, the battery may go into sleep mode when not in use. If it sits unused for too long, it might pose a problem, but I think in most cases, it's just limiting the voltage usage and notifying you via the app. This would only be an issue if the vehicle doesn't start. Otherwise, it's a standard message that Ford could likely improve.
Thx Curtis, I do remember reading that somewhere. So long as pulling fuse 11 doesn’t turn off other things I may want. I will look into it.I heard pulling fuse #11 underneath the floor of the passenger side will do all of the above. It's like turning off HAL 9000.........................
Consider putting a third party, quality AGM battery in your hybrid. The Mav Hybrids are already configured for AGM yet Ford put a lead acid battery in the truck because they supposedly ran out of AGMs. Putting an AGM in will be a much better match to the charging algorithm set for the truck and according to the vast majority of MTC posts, this solves the deep sleep issues. A comparatively small out of pocket cost versus the dealership inconvenience, lost time, and not having your truck. The OEM lead acid Motorcraft battery used in the Mav is a POS.
Thx again, u sure seem to know about that battery. U should work at the dealer. They knew Jack s!?!
Happy to help. AGM ( absorbent glass mat) batteries have been around since the 1980’s and were originally developed for military aircraft. They are virtually spillproof and leakproof and can even be mounted sideways. They are powerful and reliable. It’s not unusual to get up to 10 years of service from an AGM and some folks report using AGMs, stored and maintained, that were up to 15 years old. They charge faster than a lead acid battery and discharge much slower. The problem with the lead acid POS in Mav is the fact that it discharges faster than the truck can recharge it, leading to greater sulfation risk if SOC falls below 50%, and the battery setting at AGM is inconsistent with the battery type in the Mav. Save yourself a lot of trouble and consider/price an AGM. The AC Delco Gold LN1AGM is a drop in replacement for the OEM battery with a greater CCA than the OEM lead acid.
