Renault 4 E-Tech Battery: Complete Guide
The Renault 4 E-Tech battery is a 52 kWh NMC pack (55 kWh gross) — the same battery used in the larger Renault 5 E-Tech.
It delivers 241–247 miles WLTP in the UK. DC fast charging peaks at 100 kW, completing 15–80% in approximately 30 minutes.
Standard equipment includes a heat pump, V2L (Vehicle-to-Load), and V2G (Vehicle-to-Grid) capability across all trims. The Renault 4+ launched in the UK in late 2025 — and is currently eligible for the £3,750 UK Government EV Grant, starting from £23,445 after grant.

The Renault 5 and 4: Same Platform, Different Body
The Renault 4 shares the AmpR Small (CMF-BEV) platform with the Renault 5 E-Tech. Both use the identical 52 kWh battery, 110 kW motor, and 100 kW DC charging system.
The key difference is body — the Renault 4 is approximately 12 cm longer with a more upright SUV stance, sliding rear bench, and 420-litre boot. The 4 was actually £500 cheaper than the equivalent 52 kWh Renault 5 at UK launch — despite offering more space. The Renault 4 achieved 5-star Euro NCAP in 2025.
V2G: Vehicle-to-Grid Bidirectional Capability
The Renault 4 E-Tech offers full V2G (Vehicle-to-Grid) capability via Renault’s Mobilize smart charging service. This allows the 52 kWh battery to export power back to the home electricity grid during peak tariff periods. The system can export at up to 3.6 kW — turning the car into a home energy asset. V2G at this price point is exceptionally rare — Renault 4 buyers under £27,000 are getting a feature typically reserved for higher-priced EVs.
Renault 4 E-Tech Charging Speeds
| Method | Power | Renault 4 (52 kWh) |
|---|---|---|
| Level 1 (standard outlet) | ~1.4 kW | ~40 hours full |
| Level 2 (7.2 kW) | 7.2 kW | ~7.5 hours full |
| Level 2 (11 kW optional) | 11 kW | ~5.25 hours full |
| DC Fast (100 kW peak) | 100 kW | ~30 min (15–80%) |
Real-World Range
- Warm weather, 25°C, mixed driving: 4.6 miles/kWh (Electrifying.com long-term test) — approximately 239 miles real-world
- Carwow efficiency figure: 4.8 miles/kWh — approximately 250 miles in ideal conditions
- Mixed driving, Renault’s simulator (20°C): Approximately 240 miles mixed; approximately 175 miles motorway at constant speed
- Cold weather: Standard heat pump significantly limits range loss vs cars without one — Electrifying.com estimates approximately 185–200 miles in cold winter conditions
The Plein Sud: Folding Canvas Roof, Same Battery
In June 2026, Renault unveiled the Plein Sud variant — adding a full-length electrically operated folding canvas roof. The Plein Sud uses the identical 52 kWh battery as the standard Renault 4, losing approximately 4 miles of WLTP range due to the roof’s aerodynamic and weight effects. It targets UK, German, and Dutch markets specifically. A Roland Garros edition with further upgrades is expected later in 2026.
Battery Warranty
Renault covers the Renault 4 battery with an 8-year / 100,000-mile warranty against capacity falling below 70% of original. The vehicle warranty is 3 years unlimited mileage (years 1–2) then 100,000 miles (year 3). Renault ranked 6th in the 2025 Driver Power owner satisfaction survey — a strong brand reputation for reliability. Annual NMC degradation is approximately 1.5–2.5% per year under normal use.
Renault 4 vs Competitors
| Model | Battery | WLTP Range | DC Rate | V2G? | Starting Price (UK, after grant) |
|---|---|---|---|---|---|
| Renault 4 E-Tech (52 kWh) | 52 kWh NMC | 247 miles | 100 kW | Yes | £23,445 |
| Renault 5 E-Tech (52 kWh) | 52 kWh NMC | 252 miles | 100 kW | Yes (52 kWh) | £23,995 |
| Ford Puma Gen-E (2026) | 46.8 kWh NMC | 259 miles | 100 kW | No | £26,245 (after grant) |
| Vauxhall Frontera ER (54 kWh) | 54 kWh LFP | 253 miles | 100 kW | No | £25,995 (after grant) |
Charging Tips for Renault 4 E-Tech Owners
- Set daily charge to 80%: NMC benefits from avoiding constant 100% — 80% of 52 kWh provides ~42 kWh covering 200+ miles daily
- Use battery preconditioning (Techno+ and above): Entering a charging station in the sat-nav activates preconditioning automatically — essential for achieving the full 100 kW DC rate in cold weather
- Use V2G to reduce energy bills: Set up V2G via Renault’s Mobilize service — export stored cheap overnight electricity back to the grid during peak tariff periods
- Claim the £3,750 UK grant before it changes: The Renault 4 qualifies for the full UK Government EV Grant — confirm current eligibility with your dealer as grant terms are reviewed periodically
Conclusion
The Renault 4 E-Tech battery delivers 52 kWh of NMC capacity, 247 miles WLTP range, 100 kW fast charging, a standard heat pump, and the rare V2G bidirectional capability — all in a practical, retro-inspired crossover from £23,445 after the UK grant.
The 4.6–4.8 miles/kWh real-world efficiency is excellent for the class. The 30-minute DC charge is competitive. The sliding rear bench, 420-litre boot, and 5-star NCAP rating complete a genuinely well-rounded affordable EV package. The Renault 4 E-Tech is one of the most compelling value propositions in the European compact electric SUV market in 2026.
