vanwerk Posted September 28, 2020 Share Posted September 28, 2020 I've seen it mentioned in other threads before, but just thought I would upload a picture of the battery spacer in my Gen 2 Transit Connect, for those looking to use a battery that will not fit without it removed. Hopefully this helps others more quickly find info on this via search engines. I recently replaced my stock battery with this AGM battery from Rock Auto. jrm223 1 Quote Link to comment Share on other sites More sharing options...
Fifty150 Posted September 28, 2020 Share Posted September 28, 2020 So you have to remove the spacer to make your new battery fit? Quote Link to comment Share on other sites More sharing options...
Don Ridley Posted September 28, 2020 Share Posted September 28, 2020 If you upgrade from an FLA battery to an AGM it is a good idea to configure the ECU (BCM module in the TC) for the new battery type. The two battery types have slightly different charging requirements and I think Ford programmed different schemes for each type. Will the AGM work without this change? Yes. But the lifetime make be compromised and that would be a waste for such an expensive battery. Quote Link to comment Share on other sites More sharing options...

I hadn't seen this mentioned in other threads discussing replacing the stock battery with an AGM. Is this something the end-user can do on their own?

I had read a handful of other threads dealing with aftermarket battery replacements and it was suggested to remove the spacer, lest the new battery shouldn't fit.

Don Ridley Posted October 1, 2020 Share Posted October 1, 2020 You can reset the BMS with a good scan tool. I use the Forscan app with a good elml327 adapter for the OBII port. If you have the 2.5l engine, you don't have BMS. If you are computer savvy, use Forscan on a PC to change the battery type. But I admit I can't be sure it makes much of a difference.

There's nothing hooked up to the battery. When I try to read the battery's state of charge, nothing comes up on the gauge. Nonetheless, I followed through on FORScan and rest the battery monitoring system, which does not exist. I don't think that it did anything.

Don Ridley Posted January 22 Share Posted January 22 (edited) BMS was not included on the 2.5l models. Only the 1.6l Ecoboost has this feature. I don't think you have a battery current sensor unless you have BMS. Edited January 22 by Don Ridley Quote Link to comment Share on other sites More sharing options...

It's just odd that with FORScan, I can reset the BMS which does not exist. Quote Link to comment Share on other sites More sharing options...
Don Ridley Posted January 22 Share Posted January 22 Forscan is not sophisticated enough (and probably not even Ford IDS) to determine what hardware is installed for the various optional features. For example, you can activate cruise control in Forscan without having the correct steering wheel. This has caused some problems for users who inquisitively change Forscan settings to see what will happen. But apparently you are safe to reset BMS without the additional hardware.

With FORScan, when you search for battery, dozens of options appear. Apparently, FORScan sees it as an option in the various computer modules. But it does not mean that my van actually has any of those options. Quote Link to comment Share on other sites More sharing options...
