Does the Eunos Roadster II 1.6 16v need an AGM or EFB battery?

If your Eunos Roadster II 1.6 16v 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?

To find the exact battery you need, you need to know the make, model, and engine. If your car has a Start-Stop system (the engine shuts off at traffic lights), you need an AGM or EFB battery. An AGM battery can only be replaced with another AGM battery. However, an EFB battery can be replaced with either another EFB or an AGM battery, as the latter is superior.

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

The standard battery is the conventional type. The EFB battery withstands start/stop cycles better. The AGM battery is the most durable and is mandatory in cars with Start-Stop and regenerative braking. Never replace an AGM battery with an EFB or standard battery.

How do I find the right battery for my vehicle?

Use the search tool by selecting your vehicle's make and model. Our system automatically filters compatible part numbers verified by our technicians. If you have any questions, contact us via WhatsApp.

What warranty do the batteries have?

All our batteries come with the legal guarantee provided by consumer law against manufacturing defects. If a battery has a manufacturing defect, it will be replaced at no cost to the user.

How long does it take for the battery to arrive?

Under normal circumstances, batteries usually arrive within 1 to 2 days of ordering. However, there are some cases where delivery may take a little longer: peak seasons (Black Friday, Christmas, etc.), palletized shipments, occasional stock shortages, etc.

Battery analysis for your Eunos Roadster II 1.6 16V

Quick answer Depending on the equipment, your car uses one of these two main batteries. The most common option is EFB 72 Ah (260×173×225 mm): we recommend VARTA N72. Other units use EFB 65 Ah (232×173×225 mm): VARTA N65. Before buying, check the Ah on your current battery's label or measure its length.

Based on the batteries we found for your vehicle, our experts help you pick the right one.

📋 What we found

For your Eunos Roadster II 1.6 16V we found 5 compatible batteries. This list includes 4 Start-Stop batteries and 1 conventional battery (non Start-Stop).

📏 Battery size

The list contains batteries in different sizes or capacities (Ah). In many cases both variants fit, but it's worth checking your compartment dimensions and the Ah of your original battery before buying. Choose the one with the same dimensions as your current battery: a bigger one may not fit the compartment or the hold-down. If several match your size, the higher capacity gives more headroom for cold starts.

⚡ Battery type for your vehicle

Does your Eunos Roadster II 1.6 16V have a Start-Stop system? It shuts the engine off at short stops (traffic lights, jams) and restarts it automatically when you release the brake/clutch. If your dashboard has an "A-OFF" button or an engine icon with a circular arrow, it has it.

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 — Start-Stop requires AGM or EFB)
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.

Start-Stop & high energy demand batteries

AGM or EFB battery for start-stop vehicles and for cars with high energy demand (many electrical consumers, frequent starts). More charge cycles, better charge recovery and longer service life.

Does your car have Start-Stop?

Start-Stop switches the engine off at traffic lights. If your car has it, it needs an AGM or EFB battery.

Measure your current battery before choosing. In every case the positive terminal is on the right. Compatible batteries offer 65-70 Ah, 630-650 A (CCA), 12 V, case D23, conventional flooded technology. Browse the compatible battery list below.
: If your Eunos Roadster II 1.6 16v has start-stop, regenerative braking or many electrical accessories, you will need an AGM or EFB battery. Check your vehicle's technical specifications.

: In mainland Spain and Portugal delivery takes 24 working hours if you order before 6:00 pm and the battery is in stock; for the Balearic Islands and other EU destinations allow 2 to 5 days. Batteries are shipped fully charged and ready to install.
: ⚠ Then you need a battery designed for Start-Stop (EFB or AGM). We have hidden the conventional batteries from the list: fitting them in your car would ruin the battery within months and could damage the alternator. The batteries below are built for the frequent charge/discharge cycles of Start-Stop. 💡 Great. You can buy either a conventional or a Start-Stop (EFB or AGM) battery: a Start-Stop battery is perfectly valid in a non-Start-Stop car and is actually more robust (longer life, better cold-start performance). It is just a bit pricier. On vehicles older than year 2000, an EFB is preferable to an AGM: legacy alternators charge at a fixed voltage without temperature compensation, and an AGM needs a more precise charging profile to avoid losing life quickly — an EFB tolerates the classic alternator profile better. 💡 If in doubt, play it safe: buy a Start-Stop battery (EFB or AGM). It works in Start-Stop cars and non-Start-Stop cars alike, lasts longer and avoids any risk. You only pay a few euros more than a conventional one.

Guides

: This vehicle uses a conventional flooded battery: no BMS registration is required, the alternator will charge it directly.
