If you really want to buy this one (I find the price quite high, but I don’t know the specific market in Norway), buy an OBD adapter and EVScanner app on iOS with the BMW module. You can check the SOH of the battery and the general state of it as the replacement could be quite costly (around 1500 per module and you could have to replace up to the six if all fail or the BMS). I’d guess the SOH would be at best around 85%, maybe less. The engine itself is pretty reliable as it’s a detuned B48 from the 330i. Go to the infotainment and check the stats from factory and the percentage of eDrive kilometers (full electric) compared to the total kilometers, it would give you an idea of how the car was used and how much charging it got. This specific model of car is great to drive if you can charge everyday and you drive mainly short distances. I do around 80 km daily, almost all highway and my average consumption on those drives is 3.5 liters and 10 kWh/100, so it’s about 2/3 of the cost of my previous car, while beeing a lot better to drive. I’d still buy a 320 or 330i instead because there will be less things that could fail and I would probably not want to get such a high mileage PHEV without knowing how it’s been previously used. Source: I have a 330e from 2021 with 112k km and the SOH of the battery is 90% with around 1400 cycles. Average consumption since factory is 4.9 l/100 km and about half of the distance have been made fully electric.
Owner reviews for battery
I started buying AC Delco, probably now made in Korea. Anyway, 9 years in my Kia Spectra, 7 years in our rarely driven ‘02 Accord, has another in there from a year or two ago. One that was in my wrecked Cobalt, still works but is sitting. Now one for the Cavalier that had a two year old premium Everstart. The place I get the AC Delco batteries from sells a lot of them so they refresh their inventory. And they are also cheap with my business account. Was $120 for the last one, got the better option they offer. But most have been under $90. Although prices have gone up everywhere throughout various product. Just saying, for whatever reason they have been the only ones I didn’t have to warranty out every 2-3 years. Maybe I’m just getting lucky with them for the last 12-13 years. But I got tired of SuperStart and Everstart batteries that I used to go for. Duracell had been good in customer vehicles.
I've had good results from East Penn Duracell at Sam's Club. I just replaced one nearly 8 years old.
The best way to check is to go with a multimeter and get the highest voltage/closest manufactured date. Duracell might just be EverStart rebranded BUT NO the Walmart battery will last around 1-2 years, maybe less. If you want to make sure your covered with a good battery, that’s when you go to Advance Auto or AutoZone and get the battery with 3 years of warranty and swap it out right before the 3rd year ends and I find the batteries last me forever.
I prefer Yuasa.
I replaced mine with a NOCO lithium. The stock one wouldn't start when it was below 40F anymore but worked perfectly when it was warmer.
I’ve had my id3 5 years now and had very few problems with the car or charging. I’ll get maybe 180 miles on the motorway but close to 240 miles cross country. Manchester to Sheffield to Nottingham and back to Manchester left me with around 50 miles range, but I can’t get from Manchester to London, or Manchester to Glasgow without charging.
Paid charging is problematic mainly because the T8 charges so slow. You'd have to leave your car at a charger for like 5.5 hours to fill the battery.
3 yrs on a Honda battery had me smh honestly.
However if you bought an Exide battery, 100% it's your issue: I have had three batteries replaced under warranty on my BMW until I said "basta" and bought a Yuasa out of pocket. The amount of weird issues those junky batteries caused was beyond belief.
