Multimeter readings for main battery.

[Jane2019]

<t>I have a 16 plate Fiesta 1.25 Zetec. I’ve been checking the battery and found this: before start up 11.81 volts, but after driving steady for 45 mins: at first it read 12.16, but one hour later (after lunch) it read 11.80. Then I drove for 1hr 15 mins, but the battery only read 11.98 volts. This is a very small amount of charge for 75mins driving. The car is still under warranty and the Ford Dealers have recently passed this battery as in good condition. If I take it to somewhere for a free test, but where they sell batteries, they will almost certainly condemn it. I don’t know who to believe.</t>
