If you have read an overseas review of the Kia EV5, the battery it describes is not the one in the Australian car. The EV5 sold here is built in China with a lithium-iron-phosphate (LFP) pack of 64.2 kWh or 88.1 kWh — figures Kia Australia quotes without saying whether they are usable or gross. European usable-capacity figures do not apply to this car and should not be used to judge it.
The packs Australia got
| Variant | Years | Battery (as quoted by Kia AU) | Claimed range (WLTP) | Real-world consumption |
|---|---|---|---|---|
| Air Standard Range 2WD | 2025–2026 | 64.2 kWh — usable/gross not stated | 400 km | 18.2 kWh/100km — manufacturer claim |
| Air Long Range 2WD | 2025–2026 | 88.1 kWh — usable/gross not stated | 555 km | 18.0 kWh/100km — manufacturer claim |
| Earth AWD | 2025–2026 | 88.1 kWh — usable/gross not stated | 500 km | 21.9 kWh/100km — measured, AAA Real-World Testing |
| GT-Line AWD | 2025–2026 | 88.1 kWh — usable/gross not stated | 470 km | 21.0 kWh/100km — manufacturer claim |
The Earth figure is the one to trust. The Australian Automobile Association drove the car on real roads and measured 21.9 kWh/100 km — about 20% above Kia's own number for the same variant. On an 88.1 kWh pack that is roughly 400 km of real driving against a 500 km claim, and it tells you the AWD cars are thirstier than the brochure suggests.
Why the chemistry reverses the usual advice
LFP packs tolerate — and periodically need — a full charge. The battery management system estimates state of charge from a voltage curve that is almost flat across the middle of the pack, and it needs a 100% charge now and then to re-anchor that estimate. That is true of every LFP pack, and BYD and Tesla say so explicitly for theirs.
So on an EV5, "I always charged it to 100%" is normal and correct, not a red flag. And a car that has spent months at 30–70% may report a state-of-charge figure the BMS is less sure of, which can show up as odd range estimates rather than a degraded battery. It is one of the reasons a measured State of Health read is worth more than the dashboard range number on this car.
The warranty
Kia covers the high-voltage battery for 7 years or 150,000 km with a 70% capacity floor, transferable, on cars before model year 2027. That is a year and 10,000 km short of the 8/160,000 most rivals offer. Full terms: Kia battery warranty in Australia.
What to check before you buy
Which pack — 64.2 or 88.1 kWh, and whether the listing is quoting a European figure by mistake
Measured State of Health and cell voltage spread, because Kia does not publish a usable figure to compare against
When it last had a full charge, for the reliability of what the car reports
In-service date and odometer against 7 years and 150,000 km
