You need Way more than 7.5 anyway... But, have the batteries Load Tested, individually at a High Rate, after fully recharging them (best to just take them out, then you can clean all the cable ends) first before you spend the money.
I think the threshold on the older trucks (pre '01 or '02) was around 10v, newer was lowered to 8.5v but this was just PCM programming so, I think any of them could have been changed. It was an Actual requirement for the PCM to enable the Start though.
The AE will certainly do a Buzz Test, and Much more when you need it to! A wise investment for anybody who's going to maintain their own PS at @$350 w/Enhanced Ford Pkg.
