Is it time to replace my 12 volt battery

I took my 2013 C-Max we have 43000 miles on her for oil change and got the works done at the ford dealer here where i live. i ask them to make sure to check the 12 volt battery since it's a 2013 build date 03/18/2013, so the battery being just over 6 years old. The C-max has a max battery with 100 months so theoretically it could have another 27 months of life in it. Now we never had any issues with the no start that a lot of people had with the 2013 model so I have been reluctant to change out the battery. So OK they said the battery failed the load test and that it was in caution range said battery voltage was 12.4 and that the crank amps was only at 214cca not the 390cca it's suppose to be. they said it was up to me if i wanted to have them change it out but said since it's still working ok  might want to wait.  they gave me price of 130.00 for new battery and 107.00 for instillation. Iv'e thought about replacing it myself i removed the cover in the rear seems straight forward but I've read here that could be a issue with resetting the battery for charging and not sure if it would be worth saving the extra 107.00 dollars doing it myself. One other thing the advisor at the ford dealer said the mechanic could finger out where the battery even was had to look it up i guess. so makes me a little skittish having them replace it. Any thoughts on this will be appreciated thanks John

$130 for the Tested Tough Max battery is good but $107 for installation seems high as it can't be any more than 1/2 hr job including resetting battery age.  Again as I've said many times, if you have a windows laptop / tablet, you can download the "free" trial 2.3.21 beta, 2019-03-30 version of ForScan and reset the battery age.  You'd need to buy an appropriate ELM327 adapter or less than $15 to plug into OBD2 port.  You can also buy the iOS or Android lite version of the ForScan App for your smartphone for $4.99.

 

So, for around $150 you can DIY and enjoy the PID data available with ForScan.  IMO, ForScan is worth it just to monitor / set tire pressure. :)

 Thanks i was thinking of checking around to see if other ford dealers in the area had different pricing. Been checking out some you tube on changing it myself and will check in on that free trial version of ForScan. I think i'll be replacing the battery soon anyway one way or another. I do carry a jumper with me since everyone was has having issues just in case. thanks again i let you know how it turns out.
