Yes I had to get the more expensive battery also. The start/stop saves gas but not money. I disable it every trip unless I forget, but I am reminded at the first stop sign or red light, so I don't save gas or money on the battery, loose loose.Wow, I'm really educating myself today. I was checking on battery costs for my F-150. The replacement battery costs between $200 and $250. There is a replacement battery available for about $130 but it says the warranty is void if installed in a vehicle with start/stop capability. I wonder how long it will take for the start/stop feature to save me $100 worth of gas?
It may include the transmission but it absolutely includes the battery system as qualifier for needed conditions met for activation. I can sit at a red-light without moving and the start/stop will start up after a while with the AC on. The transmission had nothing to do with it starting again, I did not move. Add the fact that both vehicles start/stop started working after new battery replacement, I call it BS that it is not part of the battery/starter system.Someone told me that the auto start system in Fords was pressure actuated system in the transmission and not part the the normal battery/starter system. Was this BS?
But the conditions for the sequence to commence the Start/Stop function is connected to the charge condition of the battery.Of course all our autos need a battery but the start/stop while driving was not done via the starter.
Correct, I check this out this evening. When the auto stop was initiated at a red light I turn the steering wheel just a little and the motor started up immediately.Fords S/S system is really complex. It also won't shut down if the front wheels are turned a certain amount from straight ahead. Something about anticipating a turn.
The one question I can't find the answer to is "What battery voltage is needed for the Auto Stop/Start to work?" Ford dealership wanted a $200 electronic diagnostic fee to find out why it was not working, but speeding that money on a new battery instead turned out to be a wise decision - still operating perfectly.I was to our Ford shop yesterday for service and forgot to ask them how the Auto starter works.
Some things never change.the motor starts before the truck moves.
Not to mention annoying. Glad none of mine have it.S/S sounds complicated.
Just don't ever buy a new vehicle and you can avoid them. There are about 4 red wires to positive side of the battery, I think one of them is tied to the start/stop function and disables it if it measures too low of voltage. Disconnecting it should disable start/stop. Now all I have to do is cut the correct red wire, 25% chance of cutting the right wire 75% chance of killing the truck. The odds are not in my favor.Not to mention annoying. Glad none of mine have it.
I'm sure some college kid did his thesis showing it would save 392,871 barrels of oil a year or something.
