Hi looking for some battery advice, like others, my stop start doesn't work and a quick check with Forscan reveals its only holding 30% charge and causing stopstart to not work. Given the battery is the original from 5yrs ago, I need a new AGM battery, however I get conflicting results from online vendors as to what size it should be, and the ford sticker on the original doesn't say enough. - this is for a 1.5tdci engine - any advice on what I should be buying much appreciated ????
The battery dimensions don't have to be identical as the tray has an adjustable tab to cater for longer batteries, just ensure the terminals and height are the same really.
For what it's worth I've had this battery since late last year and my Start Stop/Heated Screen work every time so far so well worth the upgrade.
Good shout, my choice was based on someone elses recommendation so i knew it would fit, and that because I tend to do alot of short trips I knew I needed more capacity headroom so it would at least last longer between charges, but so far I must say I have been really impressed with how long it has lasted without needing a charge.
I would be keen to know how that 75AH Exide holds up, no point paying out more if you don't need to!

I would buy the one you linked to myself.Because i do short trips during the week to work and back so battery drain is heavy especially in winter with little chance to charge back properly
That was what i was trying to say (badly) in my post

Yep, think I'm going to go for the cheaper option, it looks fine and is slightly above the spec of the original ford battery [emoji106] I'll keep an eye on it with Forscan on my phone and see what happens [emoji106]
@kyutu when you changed from EFB to AGM larger capacity battery, did you change the BMS settings? Looks like you need to alter these settings when changing the battery capacity/Ah

I used FORscan to alter the Battery specifications to the closest that was available, so it isn't 1:1 but close. I don't recall changing anything else.
thanks for the info there mate - these mk5 beasts are a different world to the old mk4/4.5. Customising car configs are not quite as simple on these that's for sure lol
After much deliberation - and a 5% discount code i found for tayna (not much but half postage anyway!), I went for the Varta AGM battery with a bit more punch than the existing EFB:
Got in the car before and the screen was showing a battery saver screen - and i charged the battery (apparently) to full health 2 days ago. only time i've seen stop start kick in was after i pulled the battery for 15 minutes to try and reset the LINbus the other night. Pretty sure when i bought the car the battery had been dead as a doornail, because half the park functions weren't working until i had a drive....suspect the EFB one in there had drained to nothing and killed it off. it is a 5 year old battery mind - and underpowered considering this car has electric and electronic everything loaded into it - the power tailgate must take some juice to lift that thing alone!
Yeah I was wondering about this - I've got Forscan lite on Android phone which seems to work well with the old Bluetooth elm327 module I've had for years - not sure if the phone 'lite' version will be able to do a battery monitor reset though? I've not tried it on a laptop as yet.
pretty sure you will need full Forscan to make these changes - also i believe the gui does not work properly and you have to directly change the as-built config settings.
Thankfully, I have genuine UCDS, so will make changes through that instead!
What does that actually do? My battery was changed a good while back (original Ford 75Ah 700A Varta to Halfords EFB110) and the BMS wasn't reset, and I've had no issues.
BMS reset = relearn the battery voltages etc so it knows how healthy/full it is.
A manual BMS reset is not really needed as such because your car should perform this itself anyway, it just takes it a while to decide to do it if left to it's own devices. I think it does it overnight or after so many hours when it's not been touched, but don't quote me on that. Doing it manually is just for peace of mind and it's what garages would do.
You can do it with a combination of pedals/ignition, no need for FORscan.
Altering the battery specification that is stored in the memory however will require either FORscan or UCDS. The latest FORscan makes it super easy (barely an inconvenience!) as it's pretty much all GUI with easy to understand menus now. If you have the required adapter then it's a useful tool to have.
