Plug-in hybrids provide the perfect of each worlds—electrical driving to save lots of gas on brief journeys and a fuel engine to alleviate vary nervousness on longer journeys. Nonetheless, like all batteries, these in PHEVs degrade over time, regularly decreasing the time they will maintain a cost. There are inherent qualities and exterior forces that issue into battery degradation, which will be slowed (however not prevented) by way of habits, preservation, know-how and totally different designs. Estimates are {that a} battery will degrade about one- to two-percent per 12 months, with the typical usable lifetime of a battery spanning nicely past 10 years (although we do not know precisely how far past, but).
Most batteries are coated underneath guarantee for 8 years or 100,000 miles, so how nicely are you able to count on your PHEV’s battery to carry out by the point your battery goes off guarantee? That will depend on the mannequin and people elements we simply glossed over, and can clarify additional down. On the core, with out intending any pun, is having the fitting battery to do the right job, and proper now, there isn’t any different PHEV higher than this one, whose battery permits the longest vary proper now and 100,000 miles down the street.
With the intention to provide the latest and correct info potential, the info used to compile this text was sourced from varied producer web sites and different authoritative sources, together with the DOE, the EPA, and KBB.

Mercedes-Benz Raises The PHEV Bar With The 2025 GLC 350e
The $59,900 beginning worth for the brand new GLC 350e PHEV locations it above key rivals, however improved electric-only vary justifies it.
The 2025 Mercedes-Benz GLC 350e Is The PHEV With The Longest-Electrical Vary
The EPA Estimates Electrical Vary At 54 Miles, Decreasing To 47-50 Miles Of Vary After 100,000 Miles
The 2025 Mercedes-Benz GLC 350e is the present range-benchmark within the PHEV market, with an EPA-estimated 54-mile all-electric vary. This important accomplishment comes from a 24.8 kWh lithium-ion battery, which is sort of double that of many rivals. And though it wouldn’t have as a lot vary with a smaller battery, effectivity performs a key function, with Mercedes-Benz optimizing the electrical motor and powertrain integration, and making certain seamless transitions between electrical and hybrid modes.
In comparison with earlier GLC PHEVs, which had considerably decrease electrical ranges, the 2025 mannequin greater than doubles its predecessor’s functionality, making it way more sensible for each day electrical commuting.
How The 2025 Mercedes-Benz GLC 350e Holds Vary Higher Over 100,000 Miles
- Lithium-ion battery, identified for prime power density and sturdiness
- Mercedes-AMG System 1 battery liquid-cooling maintains optimum battery temperatures
- Battery Administration Methods (BMS) for charging and discharging cycles
Business knowledge signifies that trendy electrical car (EV) batteries usually retain 80- to 90-percent of their capability over a 10-year lifespan, averaging out to a degradation charge of one- to two-percent per 12 months. The EPA pegs common driving at 15,000 miles per 12 months, which might imply the odometer flipping over after about 80 months.
In all equity, the EPA ranking is the right situation, not the norm, and doesn’t keep in mind exterior forces like excessive temperatures, how typically the batteries are charged and discharged (and even the kind of charger used), or the way in which the proprietor drives the car. Nonetheless, with battery administration methods in place, average ambient temperatures and finest practices in driving, to benefit from preferrred acceleration and braking methods, the 2025 Mercedes-Benz GLC 350e 25.4 kWh battery ought to retain an electrical vary capability of about 47-50 miles after about 100,000 miles of driving, and 44-49 miles after 10 years.
The 2025 Mercedes-Benz GLC 350e ’s Strengths Past Vary
The 2025 Mercedes-Benz GLC 350e blends efficiency, luxurious, and effectivity in a manner few plug-in hybrids can. Its mixture of aerodynamic effectivity, turbocharged engine and permanent-magnet electrical motor, produces sturdy acceleration and easy energy supply, belying its 5,534-pound heft. It additionally handles nicely, because of the 4MATIC all-wheel drive system and an adaptive suspension. That spryness and accompanying engine be aware might result in drivers’ turning into extra exuberant of their driving, which could additionally take a toll on vary.
The car additionally helps 60 kW Direct Present quick charging, which might provide a cost to 80% in about half-hour, although PHEV homeowners hardly ever factor about that, since ideally they’d merely plug their automobiles in at dwelling, in a single day, although research point out many hardly ever plug their PHEVs in, if in any respect.

Lithium-ion batteries at present dominate the automotive utility market resulting from their excessive power density, light-weight design, and environment friendly cost cycles. As said above, they provide sturdy longevity, usually retaining 80- to 90-percent capability over 10 years, however are vulnerable to degradation resulting from temperature and poor charging practices.
Nickel-metal hydride (NiMH) batteries have been utilized in early hybrids and are nonetheless utilized in some self-charging hybrids. They’re heavier and fewer energy-dense, making them unsuitable for lengthy EV vary, however they’ve sturdy sturdiness and are much less vulnerable to excessive temperatures. Stable-state batteries are being developed by corporations like Mercedes-Benz, Samsung, and Toyota, and promise greater capability, an extended lifespan, and sooner charging with lowered degradation dangers.
EV Batteries Are Influenced By Geography, Charging Habits And Driving Kinds
Battery life and power retention are influenced by good power use (by way of manufacturing and software program), geographical local weather and terrain variations, quick charging practices, and regenerative braking and driving types.
Excessive warmth hurries up battery degradation, excessive chilly climate reduces effectivity, and hilly or mountainous areas require extra energy, which will increase put on. Quick charging, whereas handy, generates extra warmth, which accelerates battery degradation if steadily used. Regenerative braking recovers power and reduces pressure on the battery. Good power use, akin to preconditioning the battery and optimizing charging cycles, helps protect longevity.
Finest Practices For PHEV Battery Longevity
- Use Stage 2 (dwelling) charging when potential to attenuate warmth buildup.
- Regulate local weather publicity by parking in shaded or temperature-controlled areas.
- Use regenerative braking to get well power and never overwork the battery.
- Hold battery cost between 20- and 80-percent.
- Keep away from aggressive acceleration and high-speed driving.
