I am trying to find a formula for all cells that can take my battery dates that are 3 years old of the current date and or older that show highlighted red. I have used the formula =J10<TODAY()-1095 and it works for one cell but I cannot figure out how to us it for all cells. Please help
 
So the first sell I want to format is F1 format would look like =F1 < TODAY()-1095

Second cell would be F2 and the format would loo like =F2 < TODAY()-1095

The formula is taking any battery date 3 years and older from todays date and highlighting it red to show that it needs replaced. and eventually I would like to find out if I can get and automated email generated when that Cell turns red saying batteries needed updated at site etc.

OK, so if you wanted to apply this Conditional Formatting to all cells in the range A1:AC110, do the following:
- Select all the cells in your range A1:AC110 with your mouse
- Go to Conditional Formatting
- Enter the following Conditional Formatting formula:
Code:
[COLOR=#333333]=A1 < TODAY()-1095[/COLOR]
- Choose your red formatting option
- Click OK to complete

okay so I did that and it worked but I have some dates in there that are not 3 years old and it was highlighted red? I'm wondering why that is

Can you provide some sample dates that are not working for you?
Also, are you sure that those are actually date entries and not dates entered as text?

Here is one easy way to check. Let's say that the date in question is in cell F1.
Then in any empty cell, enter this formula and see what it returns:
=ISNUMBER(F1)

If it returns FALSE, you do not have a valid date entry in that cell.

That is interesting. The cells that are not comin gup when I tried a few to see if it would work are J10 with date 6/6/2013 and F10 with date 6/8/15. The 6/8/2013 date is correct to be highlighted but then lets say I just updeated it to 6/6/2018 it still shows red when It shouldn't. so I typed what I said in a blank cell and it does come back false but there is no date entry in there so it should come back false right?

Do you have calculation mode set to "Manual"?
What happens if you press F9?

I am not sure how to check to see if I have calculation mode set to Manual. Nothing happens when I press F9.

Are you sure that you removed ALL old Conditional Formatting conditions that you have in there?
You may have some old ones interfering.
Also, do you have any merged cells in your range?
