What battery fits the Renault Megane E-tech Suv Ev40?

Renault Megane E-Tech SUV EV40 (131 hp, electric, from 2021) takes a 50 Ah, 550 A EFB battery (207 × 175 × 190 mm), with the positive terminal on the right. Compatible batteries offer 50 Ah, 540-550 A (CCA), 12 V, case H4/L1, conventional flooded technology. Browse the compatible battery list below.

Does the Renault Megane E-tech Suv Ev40 need an AGM or EFB battery?

If your Renault Megane E-tech Suv Ev40 has start-stop, regenerative braking or many electrical accessories, you will need an AGM or EFB battery. Check your vehicle's technical specifications.

What type of battery does my car need?

You need the make, model and engine. If your car has Start-Stop (the engine switches off at traffic lights), it needs an EFB or an AGM battery, depending on what it came with: if it has an AGM, fit another AGM; if it has an EFB, another EFB or an AGM. On cars with battery management (BMW, Mercedes, VAG group…), moving from EFB to AGM requires coding the new battery. Without Start-Stop, a conventional battery is fine, or an EFB or AGM if you want a longer life.

What is the difference between AGM, EFB and standard batteries?

A conventional (lead-acid) battery is for cars without Start-Stop. An EFB is a reinforced conventional battery for basic Start-Stop. An AGM offers the highest performance and is fitted as standard on cars with advanced Start-Stop, regenerative braking or high electrical demand. Replacement rule: an AGM only with another AGM; an EFB with another EFB or an AGM; a conventional battery with any of the three. Never move down in technology.

How do I find the right battery for my vehicle?

📋 What we found

For your Renault Megane E-Tech SUV EV40 we found 6 compatible Start-Stop batteries.

⚡ Battery type for your vehicle

Your Renault Megane E-Tech SUV EV40 has no Start-Stop, but the manufacturer fits an AGM or EFB battery as standard because the charging system requires it. Choose one with the same technology.

🔋 Technology (AGM / EFB)

Do you know whether your car's current battery is AGM or EFB?

Check your battery label: "AGM" or "VRLA" means AGM; "EFB" means EFB. If it says neither, it is probably conventional: on a Start-Stop car, ask us before buying. Never fit a conventional battery on a Start-Stop car, nor an EFB where an AGM was fitted.

Before you buy: check 3 key points

Although the batteries shown are sourced from information provided by manufacturers, we recommend checking on your current battery:

Dimensions (length × width × height, including terminals and protrusions)
The dimensions shown are the maximum of the battery and include the height of the terminals, small ridges at the base and any lateral protrusions. Measure your current battery completely, from edge to edge. The new one must be the same size or slightly smaller — never larger, it would not fit in the housing.
Positive terminal (left or right viewed from the front — check the battery photo carefully)
Stand facing the battery, with the manufacturer's label facing you and the terminals on top. Locate the terminal marked with +: if it is on your right, it is "positive right"; if it is on your left, it is "positive left". Do not rely on how the battery is mounted in the car — the position is always measured looking only at the battery itself.
Technology (AGM, EFB or conventional — the same as your current battery or higher)
Depending on the manufacturer, the same technology may be labelled differently: AGM may also appear as VRLA, AGM Start-Stop or AGM Deep Cycle. EFB may appear as EF, EFB+ or Enhanced Flooded Battery. Conventional may appear as SLI, Lead-Acid, Wet or Standard. If your vehicle has Start-Stop, the battery must be AGM or EFB — never conventional.

If you have any questions, just ask us and we'll be glad to advise you with no obligation.
