Replacing main drive battery

[JonPaul]

I'm in the UK. I think my Outlander PHEV (2018) needs a new drive battery. Despite its age it has only 28,000 miles on the clock, but the battery is now only giving me 20 miles on pure EV. Does a drive battery change have to be done by a main dealer, for an exorbitant price, or can others near me (HR9 postcode) do it?

I am told these guys do Outlander batteries - not used them myself so DYOR

You should check your battery using PHEV Watchdog with an OBD2 Dongle.
20 miles is probably par for your age of car. My 2016 gets about 20 miles in summer and only about 15 at this time of year. My battery is at about 73% of new capacity.

Is the 20 miles on ev only with the heater on and a cold hilly area? Thats not bad! Mine just did similar and returned 14 miles on a full charge. You will get nearer 30 in summer on flat surfaces around town.

2019 2.4l

2018 car is still in the 8 year 70% battery warranty. As suggested above get the PHEV watchdog and check capacity

20 miles sounds about right to me.

20 EV miles are very good for 2018 PHEV, mine 2018 only got 10 EV miles with 96k miles on her. You don't need to change the track battery at all.

Oh, come on, we've had unusually cold weather in the UK for the last 2 weeks and, if I recall in the 2018 model has the smaller battery.

Also the mileage is largely irrelevant to battery age in a hybrid, it is the number of recharges that wears it out. So if most of the driving has been on pure EV then the battery will be much older than a car only driven with the ICE for the same mileage.

But the other points about heater and hills are valid, as well.

Don't worry.
I have a 2018 model - It's the 2,5 liter with the slightly bigger battery (2018 was the switchover year so Mine is a 2019 MY even though it was first registered in 2018).
I'm at 86000 Km (53 000 miles)
Anyway, today I was geting 33 Km on the guessometer , that's about 20 Miles.
My SOH is around 73%, down from 75% a couple of years ago when I bought it.
Things will get better in the summer ! One day last summer I got a 50Km prediction on the GOM.

Don't worry about it, just drive it and enjoy !
In a 5 or 6 years time I'll start thinking of replacement cells, there's absolutely no hurry at the moment.

I don't think you have an issue with the battery. You should reset it. There were many posts to advise how to reset the battery. As someone said it is the winter. Wait until the cold season is over and reset it. 2018 is one of the best models. They have less issues than the newer models.

My 2019 2.5L with 51K miles has sat for 2 weeks since charging. Today it still showed 19miles on the GoM with climate turned on, no ECO mode etc. The aux battery showed 11.7v when power to ACC, no issues starting nor any odd alerts etc. Once in Ready mode, voltage to the aux rose to the usual 14.4v and gradually tapered down on the 38 mile journey. Still feel that the aux daily top-up doesn't keep up with the drain but even after 3 weeks sitting it's not caused any issues so far. I swapped out the OEM aux for a Optima yellow top a year or so back, lower capacity but supposedly deep discharge capable.

Worth getting the battery SoH/SoC checked before deciding to spend on replacing the battery, esp since 20 mile range at this time of year ain't bad at all. I'll see perhaps 23 miles in warmer weather but I don't drive it like my granny to 'improve' the range based on prior driving style ;-)
