Does the Austin MINI II 1100 Special need an AGM or EFB battery?

If your Austin MINI II 1100 Special 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.

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.
