Hybrid Battery Cable Issue and Voltage Drop....

[Johnkn]

On my 7-month 6k mile Hybrid I noticed a low voltage issue 2 weeks ago. Notifications pushed to my Ford app, and the interior lights failed to come on when door was opened. I checked the +12 VDC voltage at the pins under the hood and it read +11.8 VDC. I charged the battery over night and all was well. I've driven the truck every day since then including a 2 hour drive 2 days ago. Tonight I went to get something out of the truck in my garage and noticed the interior lights failed to come on again as did the exterior light flash when the door was opened. Voltage at the pins was again +11.8, however this time I also checked the voltage at the battery and saw 12.0 VDC. The .2 volts isn't a big difference however I suspect it's indicative of a high resistance at the (failing) battery cable lug..... I had planned on just buying a new replacement battery myself just to know I took that out of the failure equation, but now re-thinking it...

Can you say Warrenty

Can you say Warrenty

Yes, and I can also spell Warranty.......

If I can find a battery tomorrow I may just replace it so I know I've eliminated that before subjecting myself to dealer repairs and all the fun that brings with it...

Need spell check

LOL, as do I, I do a few things fairly well, unfortunately spelling generally is not on the list....

About the only battery that will fit is a Ford company labeled battery. There is a problem with the 12v battery in my hybrid truck ( only holds charge at 12.3v not 12.8-13v like a good battery)
Been low since day 1.

Yes, not much of a selection. I'm trying to find a new battery today......

More to come....
