The GLC 350e carries a 25.28 kWh battery — one of the largest in any plug-in hybrid sold here — and claims 112 km of electric range on WLTP. What it does not have is a published Australian battery warranty position. Mercedes-Benz Australia's high-voltage battery sections cover the EQA, EQB, EQC, EQE, EQS and G 580. Plug-in hybrids are not mentioned.
The pack
| Variant | Years | Battery (gross) | Electric range | Cycle |
|---|---|---|---|---|
| GLC 350e | 2026 | 25.28 kWh | 112 km | WLTP |
A 25 kWh pack that can DC fast-charge is closer to a small EV battery than to a conventional hybrid's. It will do a full cycle most days for an owner who plugs in, and it makes the GLC 350e a car whose battery is worth a proper look rather than an afterthought.
What "not mentioned" means
It does not mean there is no cover. The battery is part of the car and falls under Mercedes' new-vehicle warranty, and the EQ Owner Protection Plan's 8-year, 160,000 km battery cover may or may not be extended to plug-ins by dealer paperwork we cannot see. What it means is that nothing published by Mercedes-Benz Australia tells you the term, the distance or any capacity threshold for this battery. We have marked all three unavailable rather than guess.
If you are buying a GLC 350e, get the high-voltage battery terms for that specific car in writing from Mercedes-Benz Australia or the selling dealer. A listing that says "8-year battery warranty" is making a claim the manufacturer's own site does not. Full detail: Mercedes-Benz battery warranty in Australia.
What the assessment covers
The pack's reported State of Health, cell-group voltage spread, temperature behaviour and any stored or pending high-voltage fault codes. With no published capacity floor, a dated independent reading is the only benchmark you will hold.
What to check before you buy
The battery warranty terms in writing, because they are not published
